Oceanographers collect and study data about the motions of ocean water (waves, currents, and tides), marine life (sea plants and animals), ore and petroleum deposits (minerals and oils contained in the nodules and oozes of the ocean floor), and the contour of the ocean floor (ocean mountains, valleys, and depths). Many of their findings are compiled for maps, charts, graphs, and special reports and manuals. Oceanographers may spend some of their time on the water each year gathering data and making observations. People who infrequently go to sea do additional oceanographic work on dry land. Experiments using models or captive organisms may be conducted in the seaside laboratory.
