Oceanographers study all aspects of the marine environment and how it interacts with and influences planet Earth including humankind. We do this in diverse environments – from coastal mangroves in the tropics to the ice-covered polar regions. Because the ocean is a hostile and challenging place, ocean scientists use a variety of approaches to study it, including satellite remote sensing, computer modeling, research ships, cabled observatories, and state-of-the-art instrumentation. As an Ocean Science major at Oregon State, you will be exposed to the tremendous breadth of the marine realm.
