Oceanography also called oceanology or marine science, is the branch of Earth science that studies the ocean. It covers a wide range of topics, including marine organisms and ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within it: biology, chemistry, geology, meteorology, and physics as well as geography.
Humans first acquired knowledge of the waves and currents of the seas and oceans in

Job Duties of Oceanographers
Many job opportunities for oceanographers exist with scientific research institutions (universities) and various government agencies. Private companies who are engaged in searching for economic sea floor deposits, investigating areas for sea farming, and evaluating natural energy production from waves, currents, and tides also hire oceanographers. The job duties of oceanographers vary from place to place, but can be generally described as follows: | Geological oceanographers and geophysicists explore the ocean floor and map submarine geologic structures. Studies of the physical and chemical properties of rocks and sediments give us valuable information about Earth’s history.
