2. Biologist: A biologist can study many different arenas associated with the marine environment. They study microscopic organisms, land plants, coastal plants, aquatic plants, fish, invertebrates, mammals, reptiles, birds, and earth processes. A bachelor's degree is required to work in laboratories, for parks, for environmental organizations, as a teacher, etc. A master's degree may increase a student's options for jobs as well as pay better. With a doctorate, they can teach and do research at a major university.

3. Geologist: Geologist: There are many things a geologist can study, since geology relates to all processes that make up the Earth. Marine geologists may study the sediment on the ocean floor, the minerals and rocks in the oceans, the oil reserves below the oceans, or coastal processes that influence human and wildlife distribution.

As with a biologist, the more degrees a student pursues, more opportunities and better pay will become available.

4. Chemist: Chemist: As a marine chemist, you would be interested in the chemicals, nutrients, minerals, etc. that are in the water and at the bottom of the seafloor. Chemists study where these things come from and how they interact with the marine life and Earth processes.

5. Physicist: As a marine physicist, you would study the movement of water, what causes it, and what effects it has on marine life, chemicals in the sea, and coastal effects. Physicists may also work with meteorologists to predict hurricanes and problems associated with them, such as storm surge, to calculate coastal areas that are in danger.
