Oceanographers study all aspects of the marine environment - Marine Biologists research the many diverse habitats and the plants and animals that live in the sea. Overfishing, pollution and global warming threaten many critical habitats and there is increasing awareness of the need for conservation effort in many cases.
Working from boats, diving in submersibles, using scuba gear, or simply collecting from the sea shores - professional scientists and amateur enthusiasts are building a picture of this alien world. We still know more about the surface of the moon than we do about the deep ocean!
