Oceanographers obtain information about the ocean through observations, surveys, and experiments. They study the biological, physical, and chemical composition of the ocean and the geological structure of the seabed. They also analyze phenomena involving the water itself, the atmosphere above it, the land beneath it, and the coastal borders. They study acoustical properties of water so that a comprehensive and unified picture of the ocean's behavior may be developed. A limnologist is a specialist who studies freshwater life.
