Marine biologists do a lot of different things, depending on what specific question they’re studying. A friend of mine who is a marine biologist goes scuba diving on reefs in Okinawa, Japan, every summer. She collects a specific kind of fish, and notes where they are and their numbers. In the winter, she watches how those fish interacts with a specific bacteria in study tanks in the lab, and runs experiments on them. Her question is about how those bacteria transmit from fish to fish. Other marine biologists might collect seawater samples from boats, or survey the catch of fishing boats.
