Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean', and γραφή (graphḗ) 'writing'), additionally regarded as oceanology and ocean science, is the scientific find out about of the oceans. It is an essential Earth science, which covers a huge variety of topics, such as ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of quite a number chemical materials and bodily residences inside the ocean and throughout its boundaries. These numerous subjects replicate a couple of disciplines that oceanographers make use of to glean in addition expertise of the world ocean, along with astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography researches the records of the oceans in the geologic past. An oceanographer is a man or woman who researches many things involved with oceans, including marine geology, physics, chemistry and biology.
Branches
The find out about of oceanography is divided into these 5 branches:
 |
| Oceanographic frontal systems on the Southern hemisphere |
Biological Oceanography
Biological oceanography investigates the ecology and biology of marine organisms in the context of the physical, chemical and geological traits of their ocean environment.
Chemical Oceanography
Chemical oceanography is the learning about the chemistry of the ocean. Whereas chemical oceanography is particularly occupied with the find out about and perception of seawater residences and its changes, ocean chemistry focuses in particular on the geochemical cycles. The following is a central theme investigated by means of chemical oceanography.
Geological Oceanography
Geological oceanography is the learning about the geology of the ocean flooring along with plate tectonics and paleoceanography.
Physical oceanography
Physical oceanography researches the ocean's bodily attributes along with temperature-salinity structure, mixing, floor waves, inside waves, floor tides, interior tides, and currents. The following are central matters investigated with the aid of bodily oceanography.
Paleoceanography
Paleoceanography is the study of the records of the oceans in the geologic previous with regard to circulation, chemistry, biology, geology and patterns of sedimentation and organic productivity. Paleoceanographic research the use of surroundings fashions and one of a kind proxies enable the scientific neighborhood to determine the function of the oceanic techniques in the world local weather through the reconstruction of previous local weather at a number of intervals. Paleoceanographic lookup is additionally intimately tied to palaeoclimatology.
