Major Parts Of The Nervous System. The central nervous system (CNS) comprises of the brain and spinal cord. According to (Hull, 2011, p. 200) 'it has three functions: sensory, integrative and motor.' These functions are made possible through communication (sending and receiving messages) of the brain (mostly made up of interneurons) and spinal cord which sends information to the peripheral nervous system for distribution to the various parts of the body via motor neurons. Essays! The CNS senses and greece life, processes information, then responds to whatever message has been communicated. The peripheral nervous system (PNS) consists of nerves (brain, cranial, spinal, afferent and efferent) running to travelling, and from the CNS. It comprises of the somatic (SNS) and autonomic (ANS) systems. The SNS controls voluntary activities of the body (skeletal muscle contractions or conscious reactions to sensory information processed by the body such as reaction to pain ' a single pathway of neurons responding to activation by excitatory impulses). The ANS controls all unconscious automatic or involuntary activities of the body such as heart beat to remain alive, crying when emotional or sweating when we get hot. This is a double pathway response whereby neurons are activated by inhibitory and excitatory impulses. The ANS is i can do bad by myself subdivided into two further systems; the sympathetic and parasympathetic nervous systems. These two systems work in opposition to each other in order to maintain homeostasis.
The sympathethic system reacts to travelling, changes in the environment by stimulating activity and therefore using energy (Hull, 2011, p. 204). For instance if a person is confronted with danger, their immediate reaction is survival. They become tense, heart rate goes up, breathing becomes heavy etc as they prepare to react. This is the 'fight or flight' response. The parasympathetic system will do the opposite to the sympathetic system by placing the person into a state of rest, calm and relaxation.

Tortora, G. and Derrickson, B. eds., 2011. Principles of Anatomy Physiology. Asia: John Wiley Sons. Figure 2 ' The three main types of neurons. Neurons are nerve cells that carry information in the form of tiny electrical signals.
They are categorised into malaysia elections three different types, each fulfilling a different function. Sensory/receptor neurons (afferent) carry signals from the external environment using sensory organs (nose, tongue, eyes or skin) to the CNS (spinal cord and brain). Motor/effector neurons (efferent) carry signals from the CNS (spinal cord and brain) to the effectors. Effectors are muscles or organs of the body that enact the messages that have been passed on by the essays, brain. For example you might sense an itch on your arm and sbar nursing, your brain sends a message to your muscles to move your hand over to scratch the itch with your fingers (a voluntary action).
Relay neurons (interneurons) are found within the CNS and travelling, carry messages from receptor neurons to effector neurons or from one relay neuron to another. They connect two neurons together (sensory and letter scaffold, motor neurons). BBC GCSE Bitesize, 2014. The nervous system. [online].

Neurons are covered by cell membranes just like all cells and essays, are semi-permeable (allow certain substances to pass (permeate) through them).
The outside of the cell contains excess sodium ions the inside of the cell contains excess potassium ions (K+). Ions are atoms of an element with a positive or negative charge (Dummies, 2014). Neurons use electrochemical impulses to communicate with each other. If they are not stimulated (without impulse to carry or transmit) their membrane is polarized. Being polarized means that the sbar template, electrical charge on the outside of the membrane is positive while the electrical charge on the inside of the membrane is negative (Dummies, 2014). Travelling Essays! Negatively charged protein and nucleic acid molecules also inhabit the cell; therefore, the inside is negative as compared to the outside (Dummies, 2014). The cell is at its resting potential (a value of -70 minivolts (mV), see Figure 4. This changes when an action potential with strong excitatory strength reaches the synapse and causes the ion channels to open and allow sodium ions to elections, cross the cell membrane. K+ and Na+ pumps on the membrane allow these chemicals to still move back through the membrane allowing the travelling, cell to The Rise in Oklahoma, repolarise The more sodium ions enter the cell, the travelling essays, electrical potential of the cell changes so quickly that depolarisation occurs, meaning that the cell becomes positive again. Chemical synapses transmit chemical signals from the presynaptic neuron to the postsynaptic neuron in one direction only. An electrical impulse or action potential's arrival in the presynaptic neuron, is malaysia elections reaching the axon terminal.
It cannot cross the travelling, fluid-filled synaptic cleft, but neurotransmitters or chemical messengers can carry the message forward. Ions (charged particles that allow change of electrical properties across the membrane) allow the sbar report template, messages to travelling essays, move on from one neuron to another or to letter scaffold, an effector.

A synapse is a gap between adjacent nerve cells where impulses must be able to cross.
It comprises a presynaptic neuron (messengers), synaptic cleft (neurotransmitters) and post-synaptic neuron (receptors). Neurotransmitters pass across the gap causing depolarisation of the surface membrane of the travelling essays, target cell to occur. Figure 4 - Structure of the Synapse. Different types of stimuli will cause the synapse to be either inhibitory or excitatory to the impulses depending on their composition. For instance, if excitatory, the synapse will cause the neurons to become active and fire up the impulse for the receptors to receive it. For example; sound causes some ear receptors to respond. If inhibitory the synapse might cause the impulse to diffuse or deactivate. However, regardless of malaysia, what stimuli, the permeability properties of the cell's plasma membrane change very briefly (Marieb, 2009, p. 237). It is possible for neurons to have several action potentials travelling along their axons (route by which all impulses travel) at the same time.
However there are several factors that affect the speed at which the travelling essays, impulse travels. For instance; impulses travel faster in myelinated (covered in myelin sheath) neurons; temperature affects the speed of conduction of impulses; and impulses are generally faster in an axon with a larger diameter (Biology.net). The refractory period (rest period between signals) is also a speed determining factor. After the neurotransmitter has transmitted an impulse, it is b anthony poem released by the receptor and goes back into the synapse (Dummies, 2014). It is stored in the synaptic vesicles. Here the cell recycles the degraded neurotransmitter. The chemicals go back into the membrane so that during the next impulse (action potential), when the synaptic vesicles bind to travelling, the membrane, the complete neurotransmitter can again be released for another episode of report, impulse transmission (Dummies, 2014).

Thain (2009) describes the reflex arc as 'the neural circuitry involved in a motor reflex, comprising a sensory neuron, a motor neuron and usually one or more interneurons (excitatory or inhibitory) interposed between these two'. It is a rapid protective behaviour involving taking voluntary action such as pulling a finger away from exposure to sbar nursing report, a flame as shown in Figure 6. Here, a pain receptor in the finger transmits signals via a sensory neuron to the spinal cord where the travelling essays, message is received by interneurons, which respond by sending signals back to the affected area via a motor neuron with information about what response to activate. In this case the response is to contract the elections, muscles and move the finger away from the flame. This is a voluntary action where the brain makes a note of what happened and retains the travelling essays, information should it be required for any such experiences in the future. Thain, M., 2009.

About Of Earthquakes! eds., 2011. Principles of travelling, Anatomy Physiology: volume 1 2. Asia: John Wiley Sons. Metabolism is a process whereby nutrients become involved in an incredible variety of biochemical reactions inside the life style, body cells (Marieb and Hoehn, 2010, p.918). This is necessary to maintain energy levels and all bodily functions.
Enzymes in the digestive system break down the food we eat and essays, convert it into malaysia this energy. Metabolism occurs to balance our current needs against future needs of travelling, energy, knowing when to store or replenish it. Template! This is achieved via two processes: anabolism (constructive metabolism) which involves the building up of complex chemical substances from essays, smaller, simpler components; and catabolism (destructive metabolism) which is the breaking down of complex chemical substances into simpler components (Tortora and Derrickson, 2011, p. Susan Poem! 5-6). Travelling Essays! For example proteins are broken down into ancient greece life style amino acids and rebuilt to make new structures like muscle and bone through the catabolism and anabolism processes (Tortora and Derrickson, 2011, p. 7). There are many different chemicals in travelling cells and all have an effect on metabolism. The endocrine system produces certain hormones which play a greater role in the regulation of do bad, metabolism. These hormones include: Thyroxine (T4), Triiodothyronin (T3), insulin and glucagon. T4 and travelling essays, T3 are thyroid hormones which mainly regulate our basal metabolic rate (BMR) ' the speed of metabolism and is involved in the amount of energy the body requires to maintain function and stay alive e.g. movement and heart-beat. Susan! BMR increases as the blood levels of thyroid hormones rise.
The response to these changing levels is slow and takes a few days to show (Tortora and Derrickson, 2011, p.1049). Insulin is released in travelling the pancreas responding to raised levels of glucose after a meal. This signals cells to increase their anabolic activities i.e. increase glucose to transport receptors to the cell membrane as in contracting muscles or may mean the liver has an increased concentration of greece, glucose therefore releasing glycogen as a short-term response into the blood. Also, in the adipose tissues, glucose and free fatty acids bind together and store lipids long term. Travelling! This decreases blood glucose (a negative feedback loop in the parasympathetic system). Amongst other hormones, insulin can increase the Essay about in Oklahoma, metabolic rate by 5 ' 15% (Tortora and Derrickson, 2011, p.1049). In starvation or stress conditions the body is very active, blood sugar levels drop, prompting alpha cells in the pancreas to release glucagon which helps stop glucose travelling around the body and focuses on providing energy for essays, the brain.
Glycogen breaks down into amino acids and sbar, glycerol in the liver produces new glucose by gluconeogenesis or lipolysis. Fatty acids are catabolised by combining acetyl coenzyme A (coA) and oxaloacetate forming ketone fuels. Blood glucose levels increase as a result which can cause hyperglycaemia (diabetes) and low blood glucose levels (too much insulin) can cause hypoglycaemia (hypos). DLCentre, 2008/2010/2012.

The ear allows us to hear a range of travelling essays, different sounds as well as maintain our balance through head movement and i can do bad by myself, position. Although the two organs serving these two senses are structurally interconnected within the ear, their receptors respond to different stimuli and are activated independently of travelling essays, one another (Marieb and i can do bad, Hoehn, 2011, p. 574). It is connected to the brain by the auditory nerve and is subdivided into three major parts: the external (outer) ear, middle ear and internal (inner) ear. The outer and middle ear components are involved with hearing only and are simply constructed whereas the outer ear is more complex and is involved with hearing and balance control (Marieb and Hoehn, 2011, p. 574). The outer ear comprises the auricle (pinna), elastic cartilage covered with thin skin and travelling, hair sometimes. The auricle picks up sound waves (vibrations), feeds them to the auditory canal (external acoustic meatus) to end up on the tympanic membrane (ear drum).
Sebaceous and sweat glands in susan the auditory canal secrete cerumen (ear wax) which captures foreign particles and repels insects (Marieb and Hoehn, 2011, p. 574). Hearing is activated by sound waves (measured in hertz), as they hit the tympanic membrane (eardrum) causing vibration and in turn transferring the sound energy to the tiny bones of the middle ear also making them vibrate (Marieb and Hoehn, 2011, p. 574). The middle ear is located in essays the skull's temporal bone. Sound waves transfer from the middle ear (tympanic cavity) amplifying the vibrations from the tympanic membrane to the first of the auditory osscicles (bones). Do Bad By Myself! The malleus (hammer) connected to travelling essays, the tympanic membrane, passes vibrations onto the incus (anvil), the stapes (stirrup) and onto the oval (vestibular) window. The middle ear is air-filled and can sometimes be consumed with pressure (when on a plane) which can be released via the pharyngotympanic (auditory) tube linking the b anthony, middle ear cavity with the pharynx (throat) and the mucosa of the travelling essays, middle ear that lines the letter scaffold, throat (Marieb and travelling essays, Hoehn, 2011, p. 574). Swallowing or yawning opens the malaysia, usually flattened auditory tube to balance the pressure in the middle ear with external air pressure, important for travelling, the eardrum to vibrate freely without distorted sound (Marieb and Hoehn, 2011, p. 574). The internal ear (labyrinth), situated in the temporal bone comprises the cochlea, vestibule and semi-circular canals. Vibrations come from the oval window into the cochlea then fibres transmit electrical impulses via the malaysia, ganglia to the organ of corti which translate that stimulation into travelling essays nerve cell excitation and neurotransmitters transmit back to the auditory cortex of the brain along the auditory nerve (DLCentre, 2008/2010/2012). Life Style! Perilymph and essays, endolymph fluids conduct the sound vibrations involved in hearing and respond to nursing, the mechanical forces occurring during changes in travelling essays body position and ancient, acceleration (Marieb and Hoehn, 2011, p. Travelling Essays! 576). The vestibule is posterior to the cochlea, anterior to the semicircular canals and flanks the middle ear medially (Marieb and Hoehn, 2011, p. Susan! 576).
It is responsible for balance and posture. The utriculus and travelling, semicircular canal within detect tilting movements in relation to gravity and help keep the body upright. Communication to the brain is via the vestibular nerve. The eye lets us see by detecting visible light (part of electromagnetic spectrum ' wave energy that radiates from the sun). Visible light projects colour depending on its wavelength which is measured in nanometers (Tortora and Derrickson, 2011, p. 642). The eye comprises accessory structures (eyelids, eyelashes, eyebrows, the lacrimal (tear producing) apparatus and extrinsic eye muscles) that protect and sbar report, move the eye and essays, eyeball structures. The eyeball is divided into the anterior and letter scaffold, posterior chambers.
Three most visible components of the anterior chamber are: the pupil (dark dot at centre of eye allowing light onto retina); the iris (covers the pupil, colour pigmented and essays, light regulator); and sclera (orb-like shaped white, elastic substance encasing the cornea, moistened and protected by elections, conjunctiva), The cornea, (transparent, dome-shaped, and protruding from the sclera) helps direct and focus light. The aqueous humour (transparent fluid at front of lens) allows uninterrupted projection of light and maintains eye pressure. Travelling Essays! Other components include the sphincter and dilator muscles which control the size of the pupil, the ciliary body, suspensory ligaments and ciliary smooth muscles which support the lens. The posterior chamber contains components that give focus to an image. These are: the vitreous humour (transparent jelly) for pressure; the retina (layers of photoreceptors cells with rods and cones). Up to 130 million rod cells allow us to see in black and Essay about The Rise of Earthquakes, white, in dim or low light and assist with perception of objects. Travelling! Up to The Rise in Oklahoma, 10 million cone cells allow us to see in colour (blue, green and travelling essays, red) and bright, higher intensity light waves (DLCentre, 2008/2010/2012).
Having no photoreceptors at the optic nerve site creates 'the blind spot' (optic disc), The visual cortex is the final destination for visual information. Three main types of neurons that make up the neural layer (photoreceptors, bipolar cells and ganglion cells) are involved in generating action potentials (Marieb and Hoehn, 2011, p. Essay About The Rise In Oklahoma! 552). Processed information is then transported to the brain from the essays, optic nerve fibres through the optic chiasm, collecting and reducing the impulses in letter scaffold the optic tract towards the thalamus then the occipital lobe before interpretation of incoming signals occurs in the visual cortex.

Sometimes it’s the nursing report template, simple things in life that make the essays, best essays. Sbar Template? Some of my favorites have included essays that reflect on the daily subway ride to school, or what the family goldfish observed from the fishbowl perched on the family kitchen table. It doesn’t have to be a life-changing event to be interesting and informative. Don’t rely on “how to” books . Use them to get your creative juices flowing, but don’t adhere too rigidly to travelling their formulas, and definitely don’t use their example topics.

Forget the essay – play a sport and be really, really good at it. If you are also a decent student that will be your ticket. Letter Scaffold? Trust me — athletes have a huge competitive advantage in the college admissions game. Travelling Essays?

Travelling? If the violin section is a little off one night, or the lead in the play is a bit weak, it won’t really matter. I’m not cynical, just realistic.
I would avoid grammatical errors such as Martha’s “I can tell the difference between the voice of a 40-year-old and a high school senior” and greece style Mary’s (reader 1) double error: “As a faculty member who regularly catches students plagiarizing on class assignments, the travelling essays, application essay is a hint at that student’s future approach to writing assignments.” I’m certain that Martha meant “I can tell the difference between the voice of a 40-year-old and i can that of a high school senior,” and essays that Mary meant “As a faculty member who regularly catches students plagiarizing on susan, class assignments, I note that the travelling, application essay is a hint at students’ future approaches to writing assignments.” the best thing you can do is try out i can do bad a lot of ideas. Essays? my english teacher senior year made us write a different personal essay every day for poem, the first month of school. i never would have thought of my ultimately successful topic if i hadnt been for being forced to do so much writing. if you really feel you must start over the summer, try out travelling lots of ideas and dont commit. ask an english teacher or recent ivy grad for advice, your parents may not have the Essay The Rise of Earthquakes in Oklahoma, best sense of a relevant and not trite topic. once you have your topic, draft and fine tune. i went through at least 40 full drafts. luckily my topic answered every essay question i came across. finally, i think the mundane topics advice is risky.

As the parent of two college-aged sons, I could not agree with this advice more. I Can By Myself? One wrote about a challenge that he overcame and the other about being compassionate. Both essays were about events that happened in their everyday school lives. Both were written in active voice and were little windows into their characters. Neither used the words challenge or compassionate. I am convinced that it was the strength and sincerity of their essays that opened the doors at the top schools that said “Yes” to my sons.

She was accepted at every small college she applied. Rejected at Harvard, Yale, wait-listed at Columbia (and then told there is no place) and at Duke….but then, 25 of 26 applicants from her (public) school were rejected from essays, Yale…the one acceptance: a superb musician, triple-legacy, Presidential Scholar. She IS an athlete, but not good enough to play at i can do bad by myself the schools that rejected her (and plans to at the essays, small college she will attend). Oh…she’s upper middle class white (and competing in letter scaffold a major metropolitan area against many white legacy kids at these top schools). “been through it” might think himself realistic for advising that everyone get ‘really really good’ at a sport, but being a non-sports person with a non-sports kid, our (IMO rather more sure-fire) resolution to this particular problem is travelling essays, – – apply only to technical colleges; they do not require essays. Tongue only b anthony, partly in travelling essays cheek… Not all Ivy League admits use coaches or guides- I didn’t.
I took a risk in writing my application three years ago- I wrote a genuinely personal essay. It was frightening for of Earthquakes in Oklahoma, me to essays do bec it revealed things about malaysia elections my background that I wasn’t sure Harvard could handle. Travelling? But it was a risk that paid off. So, my perspective is- take a risk, expose yourself, share why admission truly matters to i can you. Thank you, Ms.

That is, just write it quickly with whatever comes into travelling essays your head (on the topic) without caring if the essay is good and bad.
Then let a trusted person compare the versions. Sometimes the latter turns out to have the better “flow,” and you can improve on malaysia elections, that in the editing process. It’s a little cynical to suggest that all Ivy League admits use coaches and guides. A friend currently at Yale was told by a college counselor that her essay was terrible (it read too much like a “story” and didn’t have a “message”), and she sent it anyway. I wrote my essay on my own and got into essays a school famous for its English program. Probably the do bad by myself, best advice is to stay far away from travelling, “moral of the story” lines.
I’ve seen plenty of letter scaffold, books that praise essays about the writers’ overcoming of obstacles, blah blah blah, with all their lines about travelling “through my experience, I learned…” I would get pretty darn bored of that if I were an admissions officer. Neither of b anthony poem, my children used a coach or had special classes. We checked the grammar and spelling on their essays and let them focus on their interests in and out of school. One is at an Ivy one is at a small, tier one school. I expect the one going to the small school will get the travelling essays, better education. Some advice that not every student would need, but could be helpful to malaysia elections many:
1 – Don’t try to travelling sound too “intellectual,” if that means stuffing the essay with high-brow vocabulary that you would never use in an ordinary conversation. If you sound like you’re trying to letter scaffold impress the reader with this vocabulary, you probably are – negatively. 2 – If you were sweating and essays stewing with your essay, try another draft version in letter scaffold a “devil may care” frame of travelling, mind.

Barbara’s #2 is a great solution to any time one gets ‘writer’s block’. Greece Life? From Thank You notes to funding proposals, it works.

What work of art, music, science, mathematics or literature has surprised, unsettled or challenged you? : A 64-slice CT scanner that the local hospital that I volunteered at travelling essays had just gotten. 2. What’s your favorite word and why?: Determination (Probably not the sbar template, “best” choice but it really is and I think I showed it was genuine) 3. Choose any topic of your choice: I wrote a descriptive essay of my trip to the Eiffel Tower and how I was blown away by the beauty and grandeur of the structure. And this was also an essay that I had used in travelling an English class for a writing contest and b anthony poem my teacher had rated the paper as an A+ so hey, it was probably my best writing. Currently at the University of Virginia as a 3rd year student. Admissions does sometimes seem like a lottery… And Doc? Does your daughter’s school mascot happen to be a rocket?

As someone who was admitted to some Ivy Leagues and travelling essays waitlisted at some Ivy Leagues, and letter scaffold who played a sport but was not recruited, I must say that the essay was probably the travelling essays, key in helping me stand out from the thousands of middle-class, white, suburban applicants. The essay is really one of the only aspects of the application in which you can show who you really are. Resumes are nice, but they show what you do–which is meaningless unless this provides insight into who you are and how your character’s been shaped by what you do. I’m sure many people would probably make blanket statements that are hard to understand…”don’t write about susan poem something too grandiose” “don’t write about something too mundane” “don’t make it too intellectual-sounding” “don’t make it sound like intellectualism is not a part of your life”–but the travelling, best advice I can give is figure out a writing style that works for do bad, you, and essays run with it. If you look hard enough, you will find people in your life who know you well enough to give you tips on i can, your writing style while staying true to yourself and making it genuine. Take this advice with a grain of salt.

They are looking for true insight into your character, and you should seize this opportunity to reveal what it is that makes you who you are.

Investigation of the travelling essays, Role of Segmentation and Magmatism in Continental Rifting Exploiting Diverse Seismic Datasets from the East African Rift System. For many years it has been accepted that continental breakup occurs by extension and ultimately rupture of the lithosphere. However, the emergence and early evolution of two fundamental characteristics of Essay about divergent plate boundaries, segmentation and magmatism, are not well understood because most studies focus on mature or successfully rifted margins. Additionally, there are few existing datasets that can be integrated to provide 3D constraints on rift architecture throughout the lithosphere, which are required to address these questions. My research focuses on investigations of the travelling essays, crust and uppermost mantle structure beneath two unique end-member study locations within the by myself, East African Rift System (EARS). The first component of essays my dissertation concerns the mature Main Ethiopian Rift and i can by myself, Afar Depression.
I used earthquake and continuous data from travelling, 100+ temporary seismic stations located in the region to investigate the shear velocity and radially anisotropic structure of the uppermost mantle. This investigation produced estimates of mantle temperature and melt content within the rift and also highlighted the potential location of report melt segregation along a steeply dipping lithosphere-asthenosphere boundary. The second component of my dissertation focuses on the relatively immature Malawi Rift located at the southernmost tip of the EARS. For this study I am using the travelling, recently acquired SEGMeNT active and passive source seismic dataset that comprises a 3D array of ancient life on-land and lake-bottom broadband and short period seismometers. Travelling Essays? With this data I plan to investigate the shear velocity structure of the uppermost mantle beneath the region using teleseismic and about The Rise, ambient noise seismic processing. The 3D active source dataset acquired by short period lake-bottom seismometers within Lake Malawi will provide high-resolution images of travelling shallow crustal velocity structure. Together these diverse datasets will yield novel constraints on the state of the Malawi Rift and the role of segmentation and magmatism in an immature continental rift setting.

In my first chapter, I examine the ancient greece life style, effect of travelling essays short-term tidal cycles in the ocean. Specifically, I assess triggering of seismic activity related to the true fortnightly and fortnightly modulations of diurnal and semidiurnal tides at the East Pacific Rise through a dataset from an sbar nursing template Ocean Bottom Seismometer array that was deployed from October 2003 to January 2007. Travelling Essays? The study is particularly focused on seismicity before and after a well-documented submarine eruption at this site, which culminated in a seismic crisis on January 22 nd , 2006. This study enables us to observe the fundamental change in the state of stress along a mid ocean ridge through a plate spreading event.
For my second and malaysia, third chapter, I am looking at the morphology, origin and travelling, evolution of Pleistocene submarine canyons at the New Jersey margin. For this purpose, I am using the 2D seismic reflection profiles collected on R/V Oceanus cruise 270 in 1995. Mapping the submarine canyons allows me to i can, study their progression in morphology through space and time. For a greater understanding of the effects of sea level change on a stratigraphic column, a 3D seismic volume was just acquired on the New Jersey continental shelf, aboard R/V Langseth in the summer of 2015.

Mineral dust lofted up into the atmosphere has both a direct and travelling, an indirect effect on the climate system. My research focuses on understanding the sbar report, ways that dust influences the climate system today, and how that influence has changed in the past. In particular, we can use dust as a tracer of past atmospheric circulation patterns: by travelling essays, comparing the radiogenic isotopic “fingerprint” of places where the dust might have come from with the signal we see in some climate archive, we know that storm systems transported that dust from that known source to our location of interest. Then, we can see how the source areas may have changed over time. My samples come from several ice cores in West Antarctica (WAIS), and we use Sr, Nd, and Pb isotopes to malaysia elections, identify the changing dust sources to WAIS on glacial-interglacial and millennial timescales, as well as during even shorter-term events such as volcanic eruptions.

Paleoceanographic-Proxy Development in Scleractinia (Stony Corals) Throughout the Pacific Ocean: Exploring the Variable Utility of Stable Isotopes and Trace Metals in Oceanographic Reconstructions. The geochemical signature in the aragonite skeleton of a coral can be used to travelling essays, decipher past climate. In particular, stable isotopes and The Rise in Oklahoma, trace metals are used to elucidate changes in sea surface temperature (SST), sea surface salinity (SSS), or coastal river discharge. My dissertation research is a compilation of projects aimed at essays, fine-tuning and exploring the bounds of coral paleoceanographic proxies. Using stable oxygen isotopes from letter scaffold, corals off the Pacific coast of travelling essays Panama I am reconstructing decadal precipitation patterns to better understand low frequency variability in the Pacific Basin. In conjunction with the susan poem, precipitation record, I am studying the viability of coral Ba/Ca as a terrestrial run off proxy in the same region to better understand the impacts of oscillating precipitation in travelling essays, the Eastern Tropical Pacific.
In addition I am developing Sr/Ca- and oxygen isotope-SST calibrations for susan poem corals in the Great Barrier Reef. This calibration will be applied to fossil corals dating back to the Last Glacial Maximum to help us understand SST change in the Great Barrier reef during the most recent glacial to interglacial transition. Ultimately, my research explores the various types of coral paleo-proxies and essays, how their applicability can vary in different oceanographic settings.

In particular, I use IR imagery to study micro breaking, momentum, heat and gas exchange at the air-sea interface.
IR imagery not only provides a measure of skin temperature, but can also be used to infer surface currents. Structures and variations in the skin temperature arise from disruption of the thermal boundary layer (TBL) as a result of wind forcing at the air-water interface and/or due to turbulent eddies generated within the water column. The TBL makes up top few micro meters of the about of Earthquakes in Oklahoma, water column and the key intermediate between the ocean and atmosphere, which plays a crucial role in heat and gas exchanges. My studies aim to travelling essays, infer subsurface and bulk water column characteristics such as turbulent kinetic energy dissipation, and water depth from non-intrusive surface measurements of the susan b anthony poem, thermal boundary layer.

Understanding the global freshwater cycle is letter scaffold of tremendous importance in order to understand and travelling, adapt to poem, future climate change. The ocean is inherently linked to the global freshwater cycle. Positive net evaporation (evaporation - precipitation) constantly remove freshwater from the travelling, surface in the subtropics creating a local maximum in sea surface salinity while the tropics are freshened by excess rainfall. To balance the loss in freshwater in the subtropics, ocean processes need to b anthony poem, mix in surrounding waters laterally and vertically. The mainly wind driven shallow overturning circulation, defined by poleward Ekman drift at the surface, subduction in the subtropics and upwelling in the equatorial regions carries the salty surface signature beneath the surface creating a subsurface salinity maximum. Recent advances in remote salinity observations and a comprehensive field campaign (NASA-SPURS) enable us to study the influence of mesoscale eddies for the surface salinity maximum as well as the subsurface salinity maximum in the North Atlantic. My dissertation aims to quantify the essays, importance of mesoscale turbulence to the surface salinity maximum in the North Atlantic and identify links to large scale climate variables using a mix of observational data and simplified model experiments. Further more I aim to identify key processes that influence the subsurface salinity maximum once isolated from the nursing report, surface forcing, hence influence the travelling essays, heat/salt transports through the The Rise of Earthquakes in Oklahoma, shallow overturning circulation. Specifically the role of double diffusive processes for travelling essays the salinity core layer and associated transports will be evaluated. Finally these results will be compared to the shallow overturning circulation and salinity maxima in other ocean basins and evaluated whether they can explain regional differences and account for The Rise inter annual variability.

Advisory Committee: Cane, Ting, D. Chen. Integrated evolution of the atmosphere-ocean coupled modes. El Nino and the Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), and Atlantic Multidecadal Oscillation (AMO) are a few significant modes of climate variation from interannual to multidecadal time scales identified from sea surface temperature (SST). It is travelling well known that ENSO dynamics involves tropical atmosphere-ocean (AO) coupling. As to the PDO and AMO, they are also viewed as the outcome of coupling, yet there is no well-accepted theory about the mechanism involved. Thus, one aim of this thesis is to explain this low frequency AO coupling and how it leads to susan, the observed climate variation.
Based on the heat budget equation, the essays, temperature variation or tendency is determined by the horizontal heat advection (by ocean gyre circulation), vertical heat advection (by upwelling or downwelling), and dissipation (interior ocean mixing) as well as the AO interface heat flux. In order to look into the ocean’s role, estimation of the b anthony, relative significance of travelling each term will be done using the output from coupled climate models. The time variation of each term will also be investigated using time series analysis tools and other statistical methods (linear inverse model) to assist the explaining of the mechanism. The basic assumption in this work is that the coupling is not a local phenomena but on a basin wide or global scale, which is fulfilled through the oceanic and atmospheric circulation. By studying this topic, we attempt to style, understand the fundamental question of how heat is transported through AO coupling within the climate system. Further question to be addressed will be how the modes of coupling will change under the global warming condition. Date Orals Passed: 4/12.
Advisory Committee: Norell, Meng, Flynn. Fossils, Morphology, Molecules: combined analyses of salamander phylogeny. Urodela (salamanders) are a major group of modern amphibians (Lissamphibia), with a long evolutionary history that can be traced back to the Mezozoic dinosaur time. Phylogenetic studies of salamander evolution have revealed sharp conflict between the hypotheses based on morphological data and/or molecular data. The proposed research intends to travelling essays, conduct combined analyses incorporating phylogenetically significant early fossil taxa, all available morphological and molecular data; a method herein termed “Fossils-Morphology-Molecular Approach” (FMM approach). Such an approach has the advantage in resolving or relaxing the morphology/molecular conflicts, and obviously the advantage in obtaining phylogenetic hypotheses with the ultimate power of scientific explanation. Nursing Report? Fossil discoveries from the Middle Jurassic to Early Cretaceous beds in northern China have provided the key material for understanding the travelling essays, origins and early evolution of modern salamander clades. The fossil material found includes the earliest known fossil record of Essay two major salamander clades (Cryptobranchoidea and Salamandroidea), and essays, the basal taxa of several modern salamander clades. These fossils, together with other Mesozoic fossils worldwide, not only increase the taxon sampling for the phylogenetic analysis to be conducted, but also represent new combinations of anatomical characters, many of which are ancestral to susan b anthony, salamander evolution. Morphological data used will include characters of salamander osteology, soft anatomy and ontogenetic development from various sources.
Characters are drawn both from careful examination of real specimens and from published literature. Molecular data from GenBank will include more than 20000 base pairs coming from complete mitochondrial genomes, ribosomal RNA and various nuclear DNA. Essays? These data will be analyzed both separately and combined. Analyses of smaller dataset (morphological dataset with/without fossils) will be performed using PAUP, whereas analyses of morphology/molecular combined dataset (with/without fossil taxa) will be performed using more powerful tools, including MrBayes and POY. Phylogenetic results of parsimony analysis will be compared with that of malaysia Maximum Likelihood and Bayesian analysis. Cladograms will be calibrated using geological time scale and the first occurrence datum of fossils (FOD).

Subglacial hydrology is one of the main controlling factors in the spatial and temporal evolution of ice flow: how the water drains underneath an ice sheet has important implications for the basal sliding condition. However, subglacial water drainage is essays dynamic in space and time and varies in a complicated manner coupled to surface hydrology. Despite recent conceptual advances, relatively little is nursing report template known about how the surface hydrology interacts with the subglacial drainage system and how it affects effective pressure and ice flow. Currently, I am working on building a 2D numerical model of subglacial drainage to investigate the coupling between drainage of surface melt water and glacier motion.
A synthetic glacier geometry is used to obtain the steady-state solutions for water pressure and subglacial conduit sizes. The water pressure solution is applied to a sliding law to calculate ice flow speed. The goal is to apply this model to essays, a real outlet glacier in West Greenland and understand how glacial hydrology affects ice motion on a catchment scale. Date Orals Passed: 4/13.

Constraining Chemical Environment and Processes in do bad by myself, the Protoplanetary Disk: Perspective from Populations of Calcium- and Aluminum-rich Inclusions and Metal-rich Chondrules in Carbonaceous Ornans-type and Renazzo-type Chondrites Respectively? On Earth, petrologic and geochemical analyses provide insight into the Earth’s bulk composition as well as the interior and essays, exterior processes that have been operating throughout Earth’s history as a planet. To understand the origin of the Earth and other terrestrial bodies, the chemical construct and dynamic processes operating in the solar nebula, a cloud of cooling gas and dust existing after sun formation, need to be constrained. The history of the early solar system is preserved in the various components in chondritic meteorites. Chondrites have never experienced the significant planetary process of differentiation, which separates metals from silicates, and remixes chemical components. Thus, they can be considered aggregates of objects formed in the dynamic, cooling solar nebula. Ca- and Al-rich inclusions (CAI) are some of the highest temperature solids formed and preserved in chondrites.
Chondrules are varied in letter scaffold, mineralogy but those containing discrete metal layers record unique conditions relating to the heating and deformation history of the chondrules with which they are associated. The chemistries , textures, and mineral crystal orientations of CAIs and chondrules directly reflect the conditions and processes in their formation in the nebula. While many previous studies have chosen to travelling essays, focus on a few objects in detail, my study aims to examine many inclusions to better understand chemical, mineralogical, and textural variations and correlations. ? A majority of my research focuses on poem high resolution, x-ray element map analysis of individual CAIs and other objects in carbonaceous Ornans-like (CO) chondrites using custom-made image analysis software. But, to obtain a more complete understanding of complementarity, or the concept that bulk CO chondrite has a solar composition while individual components do not, I am analyzing the rare-earth element (REE) ratios in individual components. Determining the relationship between object mineralogy, texture, and REE ratio will yield insight into the occurrences of various components and their relative proportions that must combine to essays, maintain solar composition within the bulk chondrite. Greece Life? This broad survey of CAIs and other objects in CO chondrites will help constrain astrophysical models, refine the order in which minerals condense from the solar nebula, and essays, further improve the formation criterion necessary to produce the observed variation. ? Chondrule formation hypotheses are many but poorly constrained. The chondrules in carbonaceous Renazzo-type (CR) chondrites have associated metal in elections, both the chondrule core and near the rim. Electron backscattered diffraction (EBSD) permits determination of metal crystal orientation. Determining the relationships between the travelling, crystal orientation and chemistry of metal nodules within and among the nursing, chondrules could yield insight into chondrule formation and travelling, deformation. Altogether, the results of this thesis work will contribute to our understanding of our solar system as solids began to form and ancient life, the journey these solids took before becoming asteroids or planets.

Advisory Committee: Class, Goldstein, Hemming. Melt depletion and essays, geochemical evolution of the susan, subcontinental lithospheric mantle in the West Antarctic Rift System. The subcontinental lithospheric mantle (SCLM) undergoes compositional changes during tectonic events such as continental rifting, subduction, and orogeny, with each event leaving behind a geochemical imprint. Geochemical mapping of the travelling, lithosphere allows us to gain a better understanding of how the continents are structured, and enables us to piece together the tectonic evolution of the continents. Here we look at the Western Ross Sea area of the West Antarctic Rift System (WARS) as a case study. My thesis focuses on using these geochemical imprints to unravel the geochemical and tectonic evolution of the SCLM in the WARS: Os isotope ratios can be used to date the melt depletion events in the asthenosphere that are considered to be equivalent to the stabilization age of the lithospheric mantle.
In this study, mantle xenoliths entrained in susan, Cenozoic basanites were collected in a transection from the rift shoulder and into the rift basin in the western margin of the WARS. Analyses of these samples provide a recent snapshot of the lithospheric mantle after major episodes of rifting. If we can trace the age of the lithospheric mantle across this margin, we can begin to understand its behavior in essays, response to rifting and subsequent structure. We repeatedly observe. 1.7 Ga depletion events across the rifted margin, indicating the i can by myself, widespread Paleoproterozoic stabilization of the travelling, lithosphere and report, dynamic thinning of lithosphere across the western margin of the WARS. Trace elements provide another means to access the depletion history of the SCLM, however the mobility and travelling, fractionation of these elements can obscure ancient depletion signatures. Nevertheless, we can exploit the behavior of these trace elements. For example, melt depletion is characterized by light rare earth element (LREE) depletions, however we observe LREE enrichments in our 1.7 Ga xenoliths. Metasomatism, the chemical alteration of a rock via melt and/or fluid, can overprint the trace element composition of a rock, leaving behind diagnostic signatures of the metasomatizing agent (e.g. LREE re-enrichment by a carbonatitic melt).
Sr-Nd-Hf-Pb isotopes can be used to constrain the role of the SCLM in the formation of letter scaffold WARS volcanism. It has been proposed that Cenozoic basaltic volcanism in the Northern Victoria Land (NVL) region of East Antarctica originated from a SCLM source that had been metasomatized during an essays extensional event in by myself, the WARS during the Late Cretaceous. Additional studies demonstrate that Nd and Sr isotope ratios plot near the HIMU field, yet Pb and Hf isotope ratios plot between HIMU and DMM. This can be accounted for by varying proportions of lithospheric mantle source that has experienced Paleozoic to Mesozoic modification due to subduction related fluids and flux melting which can incorporate fluid mobile elements such as Pb from the mantle wedge. By measuring these same isotope systems on essays mantle xenoliths, we can begin to address whether SCLM is a source for the widespread Cenozoic volcanism in the WARS. Date Orals Passed : 4/14.

Recent observational and modeling studies have shown that wintertime variability of the stratospheric circulation is dynamically coupled to anomalous weather regimes in the troposphere. The fundamental source of the coupling is planetary-scale waves which are primarily generated in the troposphere and couple vertically with the stratosphere when the zonal-mean winds are westerly. My research focuses on understanding the elections, dynamics of extreme stratospheric planetary-scale wave events and travelling essays, their coupling to the stratospheric and tropospheric circulations. My results show that the lifecycle of i can do bad upward wave propagation/downward wave reflection events are associated with vertically deep planetary wave structures that exhibit largely equal but opposite-signed time integrated impacts: a net deceleration/acceleration of the stratospheric polar vortex and an equatorward/poleward shift of the North Atlantic tropospheric jet. Downward wave reflection events are found to travelling, play a key role in the formation of strong vortex events showing that they both represent true dynamical events with strong wave-mean flow interaction. Together with the connection between upward wave propagation and weak vortex events, the results illustrate a clear dualism in stratospheric wave-mean flow interaction. Planetary wave events are focused in high-latitudes and produce large amplitude tropospheric impacts and hence represent a key dynamical pathway through which Arctic variability can impact the midlatitude circulation. My current research aims to address the question of why stratospheric planetary wave events become extreme in high-latitudes. Several mechanisms have been proposed in the literature such as stationary-transient wave interactions, instability and resonance.
A better understanding of the dynamical mechanisms responsible for ancient life planetary wave events is the subject of current research using idealized modeling. Date Orals Passed: 4/15.

This is one of the youngest and most rapidly extending continental rifts in susan b anthony, the world, and is an intriguing locality for investigating how continents break apart. The D'Entrecasteaux Islands, at the heart of this rift, comprise metamorphic core complexes that contain the world's youngest ultra-high pressure coesite eclogite, exhumed from 100 km depth in essays, just 5 Ma. B Anthony? I have applied a variety of travelling seismological techniques to investigate this region, using data from a temporary array of broadband seismometers installed by members of the LDEO seismology dept. that ran from 2010-2011.? My analysis of shear-wave splitting, using core-traversing teleseisms, shows strong anisotropy beneath this rift, attributed to crystallographic fabric in the shallow mantle caused by susan b anthony, the rate and extent of continental rifting. I have related anisotropy and travelling, shear strain in the shallow convecting mantle to predict shear-wave splitting times that are very close to the splitting times I observe, bolstering our hypothesis that the anisotropy arises from mantle fabric related to rifting. These findings shed light on how mantle flow transitions as a rift matures from letter scaffold, a small-scale extensional regime to a large-scale divergent boundary.? We conducted a body-wave tomography study in the same region, using teleseismic P- and S- wave arrivals, and essays, taking a finite-frequency approach to relate differential travel times to sbar, 3D velocity heterogeneities. The isotropic velocity model reveals a localised rift structure evident to travelling, ?180 km depth, as well as an apparent slab remnant that contains the first intermediate depth seismicity observed in this region, discovered last year by members of our research group.
Building upon this work, I developed a new method to jointly invert for anisotropy and velocity variations in this rift by simplifying the geometry of the anisotropic fabric based on the rift geometry and susan, the SK(K)S splitting results. Travelling Essays? This work revealed that the rift axis contains anisotropic material with spreading-parallel fast axis, that is breaking upwards through lithosphere that has spreading-perpendicular fast axis (aligned with the trend of recent orogenies). This exciting result demonstrated that we can actually image lithospheric breakup from the anisotropy signal. ? My next project will entail a change in direction: we are using OBS and on-land seismic data from the Cascadia Initiative’s Amphibious Array to study attenuation of the susan b anthony, Juan de Fuca plate from ridge to trench to arc. Using differential t* measurements we can investigate the variation of essays attenuation associated with plate ageing to answer questions about the nursing, plate’s thermal structure, the travelling essays, distribution of melt/volatiles, and the fate of the b anthony, asthenosphere upon subduction.

Advisory Committee: Shillington, Tolstoy, Carbotte. Controls on nursing surface processes, fluid flow, sedimentation, and faulting on active and passive. margins from multi-beam sonar and multi-channel seismic reflection data. My thesis will include at least three chapters: The first chapter is travelling focused toward gaining an understanding of surface processes, fluid flow, faulting/compaction, and sediment physical properties outboard of the deformation front at susan poem, the Cascadia Subduction Zone.
To obtain this goal, I am using 2D multi-channel seismic (MCS) and multi-beam sonar (MB) data collected offshore Oregon and Washington during the Cascadia Ridge to Trench survey in 2012. I first performed detailed p-wave velocity analysis to achieve. sub-surface perspective on seafloor surface related fluid flow features (e.g. pockmarks). Travelling Essays? I then used the derived velocities to both depth-convert the MCS data in order to measure fault offset/dip within the sediment section and provide porosity information, which I then use to decompact the sedimentary units in order to uncover the embedded tectonic signal i.e. intra-plate faulting. As an additional project, I mapped large-scale scour marks on the distal Astoria Fan and. then inverted for the source process azimuth. The azimuths all point toward the by myself, Astoria canyon, which is the essays, extension of the sbar template, Columbia River, and therefore, may be indicators of travelling essays seafloor erosion due to late Pleistocene outburst flooding events. The second chapter involves mapping amplitude variations along with specific surface seismic attributes across sub-surface paleo-channels and related rift-block bound basin unconformities within the Galicia 3D MCS dataset collected offshore Spain in the summer of 2013. The 3D volume is. 20km x 67km and has been processed to pre-stack time migration. I am then relating the amplitude variations/surface seismic attributes to current seafloor reflectivity derived from the poem, MB backscatter data in order to better constrain channel morphology and abyssal plain sand distribution as it relates to tectonic and climatic forcing processes from the travelling, Miocene to present.

As oceans redistribute massive quantities of heat across the letter scaffold, Earth’s surface, changes in their circulation are often invoked as playing an important or perhaps driving role in these past climate changes. Many high-resolution climate records, generated over the past two decades, have provided glimpses into these past climate events; however, the equivalent, detailed record for changes in the oceans overturning circulation remains elusive. My thesis research focuses on refining, Pa/Th, a proxy that will help us generate a more detailed understanding of the relationship between climate and changes in ocean overturning. Protactinium and essays, thorium are two elements produced through the radioactive decay of ancient greece style uranium in seawater. As the concentration of uranium is well known and relatively homogenous in the ocean, the disparate chemical properties of these two elements help us to understand the strength of the travelling, oceans’ circulation regime, elucidating the role of the oceans in global climate change.
Abrupt shifts in letter scaffold, the Atlantic’s circulation regime have been inferred from carbon isotopes within benthic foraminfera, geostrophic gradient shifts captured in oxygen isotope data from benthic foraminifera, and the change in essays, burial rate of 231Pa/230Th in bulk sediment.

The position of the Intertropical Convergence Zone (ITCZ) is hypothesized to play an important role in tropical circulation, in linking the climate of the northern and southern hemispheres and in predicating important changes in ocean overturning, particularly on deglacial timescales.

The Cascadia subduction zone, where the travelling essays, Juan de Fuca plate subducts beneath the North American plate, has historically produced large, approximately M9, megathrust earthquakes. Improved knowledge of the structure of the subducting crust and mantle can help us better understand the processes that control subduction, including those related to megathrust earthquakes. In Oklahoma? We use three seismic datasets to image different properties of the essays, region at different scales. (1) Wide angle ship-to-shore reflection data from the 2012 Ridge-to-Trench and COAST cruises record variations in the reflection character of the subduction interface offshore central Washington.
An approximately 35 km long region of high amplitude reflections has been observed perpendicular to letter scaffold, strike spanning the essays, coastline. These may be explained by differences in physical properties, ray geometry or a combination thereof. (2) Receiver functions calculated from the Cascadia Initiative (CI) dataset image thickness and shear wave velocities of the crust. Thus far results have imaged a low velocity zone offshore central Washington, which may indicate a weak thrust zone. (3) Surface waves (also from the CI) are used to susan, calculate the phase velocities down to upper mantle depths across the entire Juan de Fuca plate and essays, along the coast of the overriding North American plate. This will be used to look for velocity anomalies potentially associated with hydration of the mantle, segmentation of the plate along strike, or other heterogeneities. These data are complimentary to the receiver function images of the crust and will be used in a joint inversion to determine both the crust and mantle structure. In addition, many of elections these data are from instruments deployed in travelling, an offshore environment. In particular, receiver functions have been challenging to calculate at ocean bottom seismometers (OBS) in the past due to interference from the water column. Part of this research has involved characterizing the susan b anthony, noise spectra of these instruments deployed at different depths to understand the frequency dependence of different noise sources. Since studying subduction zones requires both onshore and offshore observations, this improved understanding of using OBS data is instrumental in future studies of subduction zones.

Current seismic behavior and variation of seismic reflectivity signature for sbar nursing template megathrust in the Alaska/Aleutian Subduction zone.
Great earthquakes occur in the seismogenic portion of subduction zone megathrusts. Although most subduction zones show small to moderate interplate thrust earthquakes during the intervals between great earthquakes, a few show only seismicity within the downgoing slab, not on the plate interface, even at megathrust depths. The different patterns of seismic behavior could reflect different levels of material heterogeneity on travelling essays megathrust. Letter Scaffold? Downdip of the seismogenic zone, the megathrust changes from stick-slip behavior to stable sliding. Competing models suggest that the transition is controlled by temperature or the essays, intersection of the megathrust with the susan, serpentinized forearc mantle wedge.
In some subduction zones, changes in behavior appear to be accompanied by changes in seismic reflection signature. The Alaska/Aleutian subduction zone is one of the best places to study the relation between megathrust property and seismic hazard. During the 20th century, virtually the entire Alaska-Aleutian subduction interface has ruptured in large to travelling, great earthquakes. The 1964 Mw 9.2 Earthquake ruptured some onshore area, allowing us to deploy a broadband seismic network (MOOS array) to study the poem, details of the current seismic behavior. Further west, the rupture zone of 1938 Mw 8.2 Earthquake lies completely offshore and essays, is fully accessible to marine profiling. Susan? The megathrust of the Alaska/Aleution subdction zone also exhibits large variations from locking to freely sliding along strike from recent GPS study. My thesis focuses on the seismic behavior and travelling essays, reflectivity of the megathrust in the Alaska/Aleutian subduction zone and do bad, consists of: 1. A detailed study of travelling essays seismicity recorded by the MOOS array. Letter Scaffold? We generated a seismic catalog with 8,308 earthquakes down to magnitude 1.0 with high precision and calculated 117 focal mechanisms from the data recorded by MOOS array. Travelling? Most microearthquakes are showing normal faulting mechanisms, and the direction of the T axes generally follows the dipping direction of the b anthony, slab, indicating that they lie inside the subducting slab under down-dip extension or result from plate bending.
Interplate thrust events are absent on the megathrust within the travelling essays, 1964 great earthquake rupture area. 2. Letter Scaffold?

We trace the reflections of the plate interface from the travelling essays, trench to place 140km landward on the dip profile across the rupture zone of the about The Rise of Earthquakes in Oklahoma, 1938 Mw 8.2 earthquake. Large variations in the reflection response are observed with depth. The plate interface is marked by a single, simple reflection within the rupture zone. Travelling Essays? Farther landward, 120 km from the trench, the megathrust reflection changes to a brighter and wider ( 12 s twtt) zone of reflectivity, where more abundant intraslab seismicity as well as episodic tremor and slip occur.
The change in susan poem, the megathrust reflection response appears to occur where it intersects a shallower band of reflectivity, which we tentatively interpret as the continental Moho.

Anthropogenic aerosols remain one of the largest sources of Essay about in Oklahoma uncertainty in our understanding of and ability to project present and future climate. I examine the effects of anthropogenic aerosols on regional climate in the United States, with a focus on extreme events and the southeast U.S. “warming hole”. I examine changes in travelling, frequency, magnitude, and duration of extreme temperature, precipitation and letter scaffold, stagnation events. Extreme atmospheric stagnation events, characterized by persistent weak winds and lack of precipitation, are of travelling particular concern for air quality and human health. The lack of letter scaffold ventilation and travelling, scavenging by letter scaffold, precipitation allows pollutants to build up to dangerous levels in the boundary layer. This creates a potential feedback between air pollutants (atmospheric aerosols) and essays, the meteorological conditions that contribute to extreme pollution events. Using the GFDL-CM3 chemistry-climate model, I find that aerosols have reduced the sbar nursing, frequency and magnitude of travelling essays high temperature extremes over the U.S. between 1860 and 2005, while decreasing the frequency and magnitude of letter scaffold extreme precipitation, particularly in the eastern U.S.
As a result, aerosols have largely cancelled out the travelling essays, effects of greenhouse gases over the historical period. However, emissions of anthropogenic aerosols are projected to decrease in elections, the future, unmasking the essays, impacts of greenhouse gases during the next few decades.? The modeled spatial response pattern of extreme temperatures to nursing template, both aerosols and greenhouse gases is characterized by a strong response in the western U.S., moderate responses in the central and northeast U.S., and essays, a weak or absent response in the southeast U.S., collocated with the observed “warming hole”, one of the few regions across the globe which has not warmed significantly over the twentieth century. Ancient Greece Life Style? I find that the weak temperature response in travelling essays, this region is tied to changes in the moisture budget, driven by changes in regional circulation patterns and the westward extent of the Essay of Earthquakes, Bermuda High. I will use results from multiple global climate models to evaluate how the frequency, intensity, duration, and spatial extent of U.S. stagnation events change in response to forcing from anthropogenic aerosols. Essays? I will use observations of U.S. air stagnation from greece, NCDC in conjunction with GFDL-CM3 to examine specific large-scale stagnation events (such as summer 2012) and identify key atmospheric drivers (such as changes in the Bermuda High).

The west Antarctic Peninsula (WAP) is bordered by the Antarctic circumpolar current (ACC), which flows adjacent to the continental shelf.
Below the permanent pycnocline, the ACC advects upper circumpolar deep water (UCDW), characterized by temperature and nutrient maxima. Understanding the transport of UCDW onto the WAP shelf is important for travelling essays two main reasons. Essay About The Rise Of Earthquakes In Oklahoma? Firstly, the available heat of circumpolar deep water is believed to be partly responsible for recent increased melt of marine glaciers. Secondly, as a nutrient-maximum (macro, but more importantly, micro), the transport of UCDW onto the WAP shelf influences the local ecosystem. One of the essays, primary goals of my research is to understand the processes of letter scaffold shelf-slope exchange along the WAP margins. To date, I have identified that intrusions of UCDW to the WAP shelf are episodic with a frequency of about 3-4 per travelling, month and a size on the order of the first baroclinic Rossby radius. Nursing Report Template? There is a mesoscale structure to the UCDW boluses which is travelling shown to originate in the baroclinic instability of the shelf-break current upstream. The advective component of the intruding current is susan poem coherent with the along-slope wind stress in the weather-band and intrusion sites are tied to travelling, bathymetry at the shelf break (both cross-cutting canyons and seaward-veering isobaths). Malaysia Elections? I am now testing the hypothesis that nonlinearity of the weakly stratified flow induced by wind bursts facilitates the crossing of linear potential-vorticity conserving contours and allows episodic penetration at these topographically-determined sites.
The hope is to isolate essential dynamics so as to travelling essays, extend these findings to regions of similar shelf-break and current configuration around the Antarctic continent. Topographically-independent exchange of a yet-unquantified amount may occur as well via interleaving. A parallel goal of my research is to quantify the modification (by vertical and lateral mixing) of the susan poem, intruding water mass. Since there are no microstructure observations on the WAP shelf, this largely involves parameterizations (Richardson number-based and internal wave shear/strain-based) and inversion methods applied to budgets of travelling conserved properties.

The process of travelling essays continental rifting is fundamental to modern tectonic theory, yet details of the emergence and early evolution of about in Oklahoma continental rifts are still poorly known. I use geochemical tools to reconstruct the sources and timing of rift magmas as part of an integrated study that examines magmatism segmentation - two fundamental features of nascent divergent plate boundaries. The southern East African Rift exhibits pronounced segmentation and crustal thinning despite being nearly devoid of magmatic activity. The Rungwe Volcanic Province in Tanzania is the only volcanic region in the southern 1000 km of the rift. Physical models require magmatism at the onset of continental extension, but Rungwe is too small volume and located in the wrong place to serve this purpose. A detailed investigation of the timing and travelling essays, chemistry of Rungwe eruptions could shed light on the role of these volcanoes in initiating and elections, sustaining regional extension. A number of geochemical approaches are employed to better understand how existing volcanoes developed at Rungwe. Eruption ages, obtained using Ar-Ar isotopic ratios in the rocks, help track the initiation and frequency of travelling eruptive activity in the context of regional tectonic extension. Isotopic fingerprints of these lavas give context of how the mantle source here relates to letter scaffold, sources around the globe. Petrological models of lava compositions give context of the conditions at the source of melting.

My research focuses on travelling essays the physical mechanisms and potential predictability associated with climate extreme rainfall events in South East South America (SESA), at multiple temporal scales (sub-seasonal to seasonal). I use an approach known as weather-within-climate that identifies persistent weather types through cluster analysis to of Earthquakes in Oklahoma, describe climate events with particular characteristics. I analyze the relationship between these synoptic circulation types and extratropical cyclones, meso-scale convective systems and enhanced moisture advection events (e.g., low-level jets or atmospheric rivers), also exploring different sources of potential predictability (e.g., El Nino-Southern Oscillations, Southern Annular Mode, Atlantic Meridional Mode, Southern Atlantic Dipole, Madden-Jullian Oscillations and the South Atlantic Convergence Zone behavior) for travelling these events at different temporal scales.
I have found that these weather types are not only useful to understand the physical mechanisms and identify potential predictors related to extreme events, but that they are “sensitive” to cross-timescale interactions between the different climate drivers. This led me to explore the impact of the so-called Cross-timescale Interference Conjecture on extreme rainfall events. My analysis indicates that considering cross-timescale interactions increases extreme events’ seasonal predictability in malaysia, approximately 50%-70% with respect to the more traditional approach.

A year after the earthquake, an ocean drilling expedition sampled the fault zone that slipped during the Tohoku-Oki earthquake.
I have used trace element geochemistry to essays, develop a detailed stratigraphy of the plate boundary fault zone, which gives insight into the distribution of deformation in this region. The degree of localization of slip can have significant implications for the stress state required for this shallow slip. I am also developing a biomarker thermal maturity indicator (using alkenones and n -alkanes) to life, determine whether faults in the decollement region have experienced a significant temperature rise (inferred to be the result of frictional heating). This allows us to determine which faults inferred from the stratigraphy were likely to have slipped seismically. Through a series of hydrous pyrolysis experiments, I also constrain the kinetics of the biomarker thermal maturation to estimate the temperature rise on these seismic faults. This allows us to put constraints on the maximum earthquake each of these faults may have experienced.

Here I used a kinematic model in greece life, a moving reference frame to identify overturning vortices that form in the lower portion of the ice column above a moving sticky patch. The dimensions of the vortex depends on the regional sliding velocity and on the propagation velocity of the patch. I used three example observed radar folds to constrain model parameters using data. Submitted to JGR-Earth Surface in August 2015. Basal freeze-on: Mechanisms and volumes. This chapter explores the conditions necessary to produce large basal freeze-on structures inside ice sheets. I explore the dominant factors controlling both conductive cooling and supercooling, as well as the travelling, ice flow conditions that encourage the of Earthquakes in Oklahoma, formation of essays large basal structures. I conclude with a discussion of the water supply and glaciological settings that promote basal freeze-on, as well as the Essay in Oklahoma, settings that promote traveling slippery and sticky patches.

Advisory Committee: Goldstein, Pena, B. Anderson. Neodymium isotope composition in deep waters can be considered as a water mass tracer. My research interest is to study modern and past ocean circulation using Nd isotopes and concentration. It consists of the following components: 1. The high Nd isotope ratios of North Pacific Deep Water (NPDW, ?Nd = -4) have been difficult to reconcile with the inputs as reflected in travelling, surface waters (e.g. Jones et al.
EPSL 2008). An additional volcanic component has been suggested. By Myself? In order to constrain the sources of Nd in the North Pacific, samples from the INOPEX Cruise (2009) have been analyzed for Nd isotopes. Below 2500m in travelling essays, samples from the Aleutians-Kamchatka and East Asia margins, the ?Nd values are convergent at. -3.6, consistent with NPDW. However, samples above 2500m from Aleutians-Kamchatka show higher ?Nd than corresponding depths near East Asia, consistent with higher volcanic contributions near the Aleutians-Kamchatka. In the shallowest 500m the ?Nd trends to susan poem, more positive values toward the surface (to -1.5) near the Aleutians-Kamchatka, and travelling essays, toward lower values near East Asia (to -4.6), also consistent with volcanic contributions at Aleutians-Kamchatka. The highest ?Nd at Aleutians-Kamchatka coincides with a previously reported Fe concentration maximum, interpreted as Fe mobilization from reduced marginal sediments (Lam and Bishop GRL 2008), which may also be a means of mobilizing REE.
2. Over the letter scaffold, past several years, studies have increasingly focused on the potential of external addition of Nd along water mass transport paths (for example through “boundary exchange” with particulates or addition from groundwaters), thus challenging the travelling essays, idea that Nd isotopes behave “quasi-conservatively” in the oceans. The SW Atlantic, with the major water masses involved in the AMOC (southward flowing NADW, northward flowing AAIW and AABW), is i can do bad by myself arguably the best place on Earth to evaluate how well Nd isotopes trace water mass mixing, in order to clarify its value for following the travelling, AMOC through time. We will report Nd isotope ratios of seawater collected on the SW Atlantic meridional transect of the NIOZ West Atlantic GEOTRACES Cruise Leg 3 (RRS James Cook 057), which sampled seawater profiles and elections, the sediment surface at 18 stations between 0-50°S. Most stations are sampled in the open ocean, providing a test of whether Nd isotopes show quasi-conservative mixing systematics away from continental margins. The cruise section also provides several opportunities to test the potential effects of external Nd input. 3. The modern Southern Ocean has significant input from NADW, which is reflected in Nd isotope compositions of the Southern Ocean, and when the Atlantic meridional ocean circulation weakens, so will the travelling, North Atlantic signal. I Can? Thus, present and paleo-records of the water mass distribution in the Southern Ocean will help to understand the changes of ocean circulation. Using Nd isotopes in modern seawater and fossil fish debris from sediments will help to characterize the present day and past evolution in the Southern Ocean Nd end-member composition.

The Late Pleistocene Evolution of the Black Sea. The Black Sea is a large, deep, and essays, semi-enclosed body of sbar nursing template water that lies at the interior of a series of basins connected to the Mediterranean Sea via two shallow sills characterized by an estuarine-type circulation. This hydrologic setting changed in essays, the past. Over the last 3 million years, the Black Sea alternated between two environments: a freshwater lake and a brackish-to-marine basin. The factor that controlled the preferential state is the form of the connection with the Mediterranean Sea.
The entry of salt water is limited by the height of the global sea level relative to the threshold depth of the sill in do bad, the Bosphorus portal. The last time the travelling, Black Sea connected to the Mediterranean occurred approximately 7,150 years ago as a consequence of the rising global sea level from deglaciation. This led to large changes in the basin which include salinization, sapropel deposition, anoxia, and fauna turnover. This event is clearly seen in both shelf and slope cores. Prior to the connection, the Black Sea remained very fresh and the bottom waters were more oxygenated.
Turnover occurred at malaysia elections, times the surface waters became dense enough to break the stratification. During the last glacial maximum, the Black Sea sediments have a series of sulfide spots implying that turnover was reduced. These spots disappeared when a series of meltwater pulses appear in the cores, which have a distinct brownish color and record hyper-pycnal floods. Plumes of freshwater brought oxygen to the black sea and travelling, hence, formation of Essay The Rise iron sulfide did not occur. I am studying the series of travelling these events, how they are reported in the sediments, how one dates them, and the connections between the shelf and the slope cores. I am also thinking about how these events in do bad by myself, the Black Sea connect to global and the possible implications.
