What Is a Marine Biologist?

If you're interested in a career in oceanography and marine sciences, you may have wondered, what does a marine biologist do? What is a marine biologist and what is their primary role in this field? To answer these common questions, it can help to look at a sample marine biologist job description and take a close look at some of the key roles and responsibilities of the typical marine biologist or ocean scientist. Marine biologists are responsible for performing various types of experiments and conducting research projects to study organisms in the ocean and marine life in different bodies of water. They are trained to use specialized equipment and research techniques to produce reports and collect data about specific organisms.

What Tasks Does a Marine Biologist Perform?

Marine biologists typically work in the field and may be at sea for extended periods of time. Others may work as research scientists in a lab and conduct various types of experiments on marine organisms and other animals. Observation and research are some of the key components of a marine biologist's duties, but some may work on rescue missions and other projects that involve spending long periods of time on the water.

Marine biologists are able to use their knowledge, skills and experience in a number of different ways. They may work in research centers to conduct tests and experiments with different labs, and can find jobs in both the private and public sector. Some choose to teach and will have a doctorate degree so that they can work at a college or university that offers a marine biologist program. Others may work as part of a rescue mission to support animals at sea and use their skills to help animals recover after injury.

Description of a Marine Biologist

Many people interested in a career as a marine biologist or ocean scientists wonder, what is a marine biologist? What exactly does this type of scientist or researcher study? Marine biologists are trained to study, observe, protect and manage different types of marine organisms from various types of marine environments. They study everything from microbes and marine animals, to small plants and fish populations. Marine biologists typically work in a variety of environments including wildlife preserves, lagoons, and protected ocean territory to collect organisms and sea sponges, search for bioactive drugs and also search for different types of ocean resources that can be used for other applications on land.

Some marine biologists are more focused on the research and theory side of marine biology, and work with theoretical models, lab-based research projects and simulations to explore marine life and observe various marine species. Others work to solve problems, such as why fish or marine species populations may be decreasing in a certain area, or why certain types of marine organisms are behaving in a certain way.

The nature of the marine biologist position makes this a fairly broad career path and offers a wealth of opportunities for those who are interested in research and practical applications of marine science.
