Oceanographers study the world's oceans, coastal waters, and ocean floor. They conduct research across many scientific disciplines to understand pollutants in the ocean, their effects on marine life, and how they are incorporated into ocean sediments over time. The work involves collecting samples from seas, planning expeditions, and teaching. There are several specializations within oceanography focused on specific areas of research like biology, chemistry, physics, and geology. Oceanographers require skills like withstanding isolation, working as part of a team, and strong communication abilities. Formal education often involves obtaining a B.S. in marine biology or related field, followed by a M.S. or Ph.D. in oceanography.
