The scientific study sea

The scientific study of water and Earth’s water cycle is hydrology; hydrodynamics studies the physics of water in motion. The more recent study of the sea in particular is oceanography. This began as the study of the shape of the ocean’s currents[17] but h

as since expanded into a large and multidisciplinary field:[18] it examines the properties of seawater; studies waves, tides, and currents; charts coastlines and maps the seabeds; and studies marine life.[19] The subfield dealing with the sea’s motion, its forces,

and the forces acting upon it is known as physical oceanography.[20] Marine biology (biological oceanography) studies the plants, animals, and other organisms inhabiting marine ecosystems. Both are informed by chemical oceanography, which studies the behavior of elements and molecules within the oceans: particularly, at the moment, the ocean’s role in the carbon cycle and carbon dioxide’s role in the increasing acidification of seawater. Marine and maritime geography charts the shape and shaping of the sea, while marine geology (geological oceanography) has provided evidence of continental drift and

the composition and structure of the Earth, clarified the process of sedimentation, and assisted the study of volcanism and earthquakes.[18]
