An MS in Marine Biology is usually required to get good jobs and to be able to publish on your own. You also have to be interested in biology, math and science overall. Communications is also becoming more and more vital, therefore learning to write and communicate well is highly recommended. Everyone needs a calm and friendly personality to go with their top-notch skills. Also, be respectful and effectively you will earn respect.

You need to be very interested in science because that is a fundamental base in the area of marine biology. If you are interested that means the more effort will be put into your work and that shows. Salary Salary The marine biologist salary is dependent on writing successful grant proposals.

A grant proposal is ideas that marine biologists present to the government to perform experiments that can help the environment, and if the government approves of it, the government provides the funds for the experiments.

It takes them about 2 months to write a proposal. Their proposals take on average 5 months. The official rate of pay might be k a year, which sounds attractive, but that is only if you are determined to work for it. Education is much better and covers the bulk of the marine biologist salary. To become a faculty member at a research institution, you need to earn a Ph. This takes about 5 years of additional education after an undergraduate degree, 4 years. Working Conditions Working Conditions The working environment for a marine biologist changes from one day to the next.

Most marine scientists have a laboratory where they can conduct their observations and experiments. They may spend their whole day in this lab or they may use it only part of the time. When not in the lab, marine biologists work outdoors. Their day can be influenced by such things as the weather or by the animals they study. Marine biologists may travel to outside sites to handle certain aspects of research or experiments directly.

Marine biologists may be called upon for marine-animal rescue missions, such as after oil spills, to which they may have to travel. They may present their findings at conferences or workshops. This is usually not a job that involves a lot of stress, and the benefits may include the possibility of working outdoors in attractive locations. Develop and maintain liaisons and effective working relations with groups and individuals, agencies, and the public to encourage cooperative management strategies, or to develop information and interpret findings.

They also program and use computers to store, process, and analyze data, collect and analyze biological data about elationships among and between organisms and their environment, study aquatic plants and animals and environmental conditions affecting them, such as radioactivity or pollution. They also communicate test results to state and federal representatives and the general public. They identify, classify, and study structure, behavior, ecology, physiology, nutrition, culture, and distribution of plant and animal species.

Begin this TED Study with a fascinating read that gives context and clarity to the material. In the late s, the Apollo Mission captured images of Earth from space for the very first time. These iconic photos gave people around the world a fresh perspective on our home planet — more specifically, its vast and dazzling expanses of blue.

It's perhaps unsurprising that science has subsequently established the key roles that the ocean and its marine organisms play in maintaining a planetary environment suitable for life. While the Apollo astronauts were sending back pictures of our blue planet, a scientist at the Jet Propulsion Laboratory in California was searching for ways to detect life on other planets such as Mars. James Lovelock's investigations led him to conclude that the only way to explain the atmospheric composition of Earth was that life was manipulating it on a daily basis.

In various publications, including his seminal book Gaia: A New Look at Life on Earth , Lovelock launched the Gaia hypothesis, which describes how the physical and living components of the natural environment, including humankind, interact to maintain conditions on Earth. During the same period, marine scientists including Lawrence Pomeroy, Farooq Azam and Hugh Ducklow were establishing a firm link between the major biogeochemical cycles in the oceans and marine food webs, particularly their microbial components.

In the late s and s, large-scale research programs like the Joint Global Ocean Flux Study JGOFS explored ocean biogeochemistry and established the oceans' pivotal role in the Earth's carbon cycle. Research efforts like these underscored the oceans' critical importance in regulating all the major nutrient cycles on Earth. It's now widely recognized that the ocean regulates the temperature of Earth, controls its weather, provides us with oxygen, food and building materials, and even recycles our waste.

It seems remarkable that until fairly recently many scientists believed that life was absent in the deep sea. Dredging in the Aegean Sea in the s, marine biologist Edward Forbes found that the abundance of animals declined precipitously with depth. Despite evidence to the contrary, scientists supported the azoic hypothesis, reasoning that conditions were so hostile in the deep ocean that life simply could not survive.

Extreme pressure, the absence of light and the lack of food were viewed as forming an impenetrable barrier to the survival of deep-sea marine species. But others were already proving this hypothesis wrong. During this expedition, Ross and Hooker retrieved organisms from sounding leads at depths of up to 1. Ross remarked, "I have no doubt that from however great a depth we may be enabled to bring up the mud and stones of the bed of the ocean we shall find them teeming with animal life.

The findings of these expeditions, which Wyville-Thomson published in his book The Depths of the Sea , confirmed the existence of animal life to depths of fathoms — including all the marine invertebrate groups — and suggested that oceanic circulation exists in the deep sea. In part, the expedition's purpose was to survey potential routes for submarine telegraph cables, and so the links between scientific exploration and human use of the deep sea were established in the very early days of oceanography.

The Challenger expedition was a watershed for deep-ocean science, establishing the basic patterns of distribution of deep-sea animals, and that their main food source was the rain of organic material from surface waters. In the s, the Danish Expedition Foundation's Galathea voyage established that life occurred at depths of more than 10km in the Philippines Trench. In marine explorers Auguste Picard and Don Walsh reached the bottom of the Challenger Deep in the Marianas Trench, at a depth estimated to be 10, meters--the deepest part of the ocean — where they observed flatfish from the porthole of their pressure sphere.

This feat was not repeated until when James Cameron visited the bottom of the Challenger Deep in the submersible Deepsea Challenger. While working at Woods Hole Oceanographic Institution in the late s, scientists Howard Sanders and Robert Hessler developed new types of deep-sea trawls called epibenthic sleds that featured extra- fine mesh in the nets.

When the new trawls were tested, they recovered an astonishing diversity of species from the deep sea. It became apparent that the species richness of deep-sea communities actually increased with greater depth to a peak somewhere on the continental slope between 2, and 4, meters depth. Beyond these depths, diversity appeared to decrease but not everywhere , or the pattern was unclear.

How to explain this amazing diversity in the deep sea? Initially, scientists credited the species richness to the stability of environmental conditions in the deep ocean, which would support extreme specialization of the animals and thus allow many species to coexist.

This is known as the stability-time hypothesis. Some scientists considered that small-scale variations of the sediments of the deep ocean, including reworking of seabed by animals, was important in maintaining microhabitats for many species. In the late s other scientists suggested that conditions in shallow waters allow competitive exclusion, where relatively few species dominate the ecosystem, whereas in deeper waters environmental factors associated with depth and a reduced food supply promote biological communities with more diversity.

Fred Grassle and Nancy Maciolek added substantially to our knowledge of deep-sea biodiversity when they published a study of the continental slope of the eastern coast of the USA in the early s. Grassle and Maciolek based their study on quantitative samples of deep-sea sediments taken with box cores. These contraptions retrieve a neat cube-shaped chunk of the seabed and bring it to the surface enclosed in a steel box. Scientists then sieve the mud and count and identify the tiny animals living in the sediment.

In a heroic effort, Grassle and Maciolek analyzed box cores, an equivalent of 21 square meters of the seabed, identifying 90, specimens and species. They estimated that they found approximately species per km along the seabed they sampled.

Extrapolations of this figure suggested that there may be 1 - 10 million macrofaunal species in the deep sea. What's more, some scientists argued that Grassle and Maciolek's estimates represented only a small part of the species diversity in the ocean depths. Dr John Lambshead of London's Natural History Museum pointed out that Grassle and Maciolek had not examined the smallest animals in sediments — the meiofauna — made up of tiny nematode worms, copepods and other animals.

These are at least an order of magnitude more diverse than the macrofauna, suggesting that as many as million species may inhabit the deep ocean. However, given that the latest approximation of the Earth's biodiversity is 10 million species in total, Lambshead's number appears to be an overestimate.

Scientists have since realized that there are major problems with estimating the species richness of large areas of the deep sea based on local samples. Today we understand that species diversity in the deep ocean is high, but we still don't know how many species live in the sediments of the continental slope and abyssal plains. We also don't understand the patterns of their horizontal distribution or the reasons for the parabolic pattern of species diversity as it relates to depth.

Evidence suggests, however, that the functioning of deep-sea ecosystems depends on a high diversity of animals — although exactly why remains open to conjecture. In , German scientist Alfred Wegener put forward his theory of continental drift to address many questions that engaged the geologists and biologists of his time.

For example, why do the continents appear to fit together as though they had once been joined? Why are many of the large mountain ranges coastal? And, perhaps most intriguing, why do the rocks and fossil biotas combined plant and animal life on disconnected land masses appear to be so similar? Wegener's theory provoked a major scientific controversy that raged for more than 50 years between "drifters" and "fixists. In the search for an alternate mechanism to explain continental drift, British geologist Arthur Holmes suggested that radioactive elements in the Earth were generating heat and causing convection currents that made the Earth's mantle fluid.

Holmes argued that the mantle would then rise up under the continents and split them apart, generating ocean basins and carrying the landmasses along on the horizontally-moving currents. Following World War II, scientific expeditions employing deep-sea cameras, continuously recording echo-sounders, deep-seismic profilers and magnetometers lent support to the arguments of Holmes and his fellow "drifters. These ridges were characterized by fresh pillow lavas, sparse sediment cover, intense seismic activity and anomalously high heat flow.

Scientists found geologically-synchronous magnetic reversals in the rocks of the ocean crust moving away from either side of the mid-ocean ridges. Added to this was the fact that nowhere could scientists find sediments older than the Cretaceous in age. Together, these findings suggested that new oceanic crust was being formed along the mid-ocean ridges, while old oceanic plates are forced underneath continental plates and destroyed along the ocean trenches.

By the late s, the bitter scientific debate between the "fixists" and the "drifters" was finally settled. During the next decade, scientists investigating volcanic activity at mid-ocean ridges became interested in the associated phenomenon of hot springs in the deep sea. Anomalously high temperature readings over mid-ocean ridge axes led scientists to mount an expedition in to the 2.

From the submersible Alvin, the scientists observed plumes of warm water rising from within the pillow lavas on the seabed. Living amongst the pillows were dense communities of large vesicoyid clams, mussels, limpets and giant vestimentiferan tube worms Siboglinidae.

Subsequent investigation confirmed that the giant tube worms, clams and mussels actually hosted symbiotic sulphur-oxidizing bacteria in their tissues. The discovery caused huge excitement in the scientific community. Here was life thriving in the deep sea, where primary production — the basis of the food web — was independent from the sun's energy.

Written by the educators who created The Deep Ocean, a brief look at the key facts, tough questions and big ideas in their field.

Wildlife biologists get the privilege of studying and spending time with these animals as their everyday life. I should be a wildlife biologist so I can study land mammals. Wildlife biology is a field of biology in which land animals are studied. It deals with all animals with backbones and studies individual species of wildlife, their habitats, and surrounding ecosystems Fitzgerald. It also studies how animals may interact with their ecosystem.

Even working at a department store requires sone knowledge. You need to be able to work with customers and be up to date with everything that involves the store. During my visit to mothers job I acquired some knowledge on how to manage a store. My mother works at Nordstrom as a Retail Assistant manager. Most of the time she was on the go and extremely busy. Customers had issues that she needed to solve. My mother had to fire and even hire many.

I wanted to learn because my father and step-brother were both able to juggle and I was so amazed at how easy and effortless it appeared to be for them. My father taught me standing over my bed, so the balls would not roll all over my room. I started with one ball, then added one more, and finally all three at one time.

Quickly, I found out that juggling is not an easy talent to perform. It takes constant practice, dedication, and perseverance. I accomplished. Being an aquatic biologist comes with many crazy experiences, some in college, others with diving, and some with preserving the environment. Growing up and being an aquatic biologist isn't something you would ever. From a young age, I have always been encouraged by my parents to take advantage of every educational opportunity that I could.

My mother was the first in her family to go to college, and my father was educationally gifted from his youth, so they instilled their beliefs of the importance of education in me. In the third grade, I was accepted into the Center Based Gifted CBG program, and was surrounded with other educationally driven people from that time until I graduated from middle school. My goals in life are to get a first enlist in the Navy, hope to get a job as a diver in the special operations program.

After my first enlistment is up, I want to be a diver at an aquarium where I can feed the animals; Meanwhile, I would like to attend Rosenstiel School of Marine and Atmospheric Science at The University of Miami and earn a doctorate degree in Marine Biology to become a Marine Biologist. I've always been fascinated with animals, especially aquatic life. Although, I wasn't dead-set on becoming one at first, over spring break I made my final decision.

Thinking about the studies of protecting and preserving of the ecosystems in oceans and seas and interactions among organisms and their environment just gets my full attention. I could sit for hours and hours and listen to anybody talk about these subjects and they would have my full attention, one-hundred percent. This subject has never, and never will lose my interest. As I've researched, marine biologists must achieve at certain skills, such as: public speaking, science, critical thinking, reading comprehension and active listening.

They need to be able to measure salinity, acidity, light, oxygen content, and other physical conditions of water to determine their relationship to aquatic life. Marine biologists also need to identify, classify, and study structure, behaviour, ecology, physiology, nutrition, culture, and distribution of plant and animal species. To be a marine biologist, the best subjects to study would be prerequisite subjects. Assumed knowledge, in one or more of English, maths, biology, chemistry and physics are normally required.

Because there are so many topics one could study within the field of marine biology, many researchers select a particular interest and specialize in it. Specializations can be based on a particular species, organism, behavior, technique, or ecosystem. For example, marine biologists may choose to study a single species of clams, or all clams that are native to a climate or region. Marine life is a vast resource, providing food, medicine, and raw materials, in addition to helping to support recreation and tourism all over the world.

At a fundamental level, marine life helps determine the very nature of our planet. Marine organisms contribute significantly to the oxygen cycle, and are involved in the regulation of the Earth's climate. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. References to the sea and its mysteries abound in Greek mythology, particularly the Homeric poems "The Iliad" and "The Odyssey".

However, these two sources of ancient history mostly refer to the sea as a means of transportation and food source. It wasn't until the writings of Aristotle from BC that specific references to marine life were recorded. Aristotle identified a variety of species including crustaceans, echinoderms, mollusks, and fish. He also recognized that cetaceans are mammals, and that marine vertebrates are either oviparous producing eggs that hatch outside the body or viviparous producing eggs that hatch within the body.

Because he is the first to record observations on marine life, Aristotle is often referred to as the father of marine biology. The Dominican Republic. Trace Evidence. Seattles Suburbs History.
