Consultants often specialize in one area, such as waste management, water quality, or air quality, and each specialty may require certification. A degree in environmental studies, chemistry, geology, or another related subject is enough to get entry-level work, but you will have more career options with a Master’s or Ph.D. degree.
To work in marine biology, you will eventually need an M.S. or Ph.D. College graduates who have hands-on experience in the field or laboratory tend to have an advantage when seeking entry-level work or admission to a graduate program, so try to get an internship or volunteer position during college. Marine biologists work for research institutions, universities, government agencies, television production companies, conservation groups, and more.
