What goes into being a marine biologist?

Question

im only a freshman in high school but im really interested in science and i was wondering what kind of work a marine biologist does?

Answer 1

geo ..chem and biology

Answer 2

The field of marine biology -- the study of marine organisms, their behaviors, and their interactions with the environment -- is considered one of the most all-encompassing fields of oceanography. To understand marine organisms and their behaviors completely, marine biologists must have a basic understanding of other aspects or "disciplines" of oceanography, such as chemical oceanography, physical oceanography, and geological oceanography. Therefore, marine biologists and biological oceanographers study these other fields throughout their careers, enabling them to take a "big picture" approach to doing research.

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.

One area of specialization, the emerging field of marine biotechnology, offers great opportunity for marine biologists. Marine biotechnology research presents a wide range of possibilities and applications. One focus area is the biomedical field, where scientists develop and test drugs, many of which come from marine organisms. An example of an application of biotechnology research can be seen in industry or defense, where researchers have developed non-toxic coatings that prevent the build-up of fouling organisms, such as barnacles and zebra mussels. Such coatings are useful for ships and intake pipes used in power plants.

Molecular biology is a related area of specialization in this field. Researchers apply molecular approaches and techniques to many environments, from coastal ponds to the deep sea, and many different organisms, from microscopic bacteria, plants, and animals to marine mammals. For example, molecular biology can be used to identify the presence of a specific organism in a water sample through the use of molecular probes. This is very useful when the organism in question is microscopic or similar to other organisms. The study of disease in organisms has also been aided by the use of molecular techniques. Researchers have developed antibodies that are specific to a particular virus, so that when the virus is present in the organism, detection and diagnosis is easier and faster. Likewise, new molecular techniques help scientists identify whether or not an animal has been exposed to pollutants and, in some cases, can determine the source of those pollutants. The field of molecular biology is growing and will continue to see significant advances.
