Oceanography is the science of all aspects of the oceans, in spite of its etymology. The term, oceanography, however, implies the interrelationships of the various marine sciences of which it is composed. This connotation has arisen through the historical development of marine research in which it has been found that a true understanding of the oceans is best achieved through investigations based on the realization that water, its organic and inorganic contents, motions, and boundaries are mutally related and interdependent.
The study of the ocean. The physical properties of the ocean - currents and waves (physical oceanography), the chemistry of the ocean (chemical oceanography), the geology of the seafloor (marine geology), and the organisms that live in the oceans (marine biology and marine ecology).
Oceanography (from Ocean + Greek Î³ÏÎ¬Ï†ÎµÎ¹Î½ = write), also called oceanology or marine science, is the branch of Earth Sciences that studies the Earth's oceans and seas. Oceanographers study 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.
