Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean' and γραφή (graphḗ) 'writing'), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology.
Fish stocks are subpopulations of a particular species of fish, for which intrinsic parameters (growth, recruitment, mortality and fishing mortality) are traditionally regarded as the significant factors determining the stock's population dynamics, while extrinsic factors (immigration and emigration) are traditionally ignored.

Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
Census scientists visited many parts of the global ocean to learn more about species ranging in size from the blue whale to minute zooplankton and microbes (bacteria and viruses); sampled from the world's coldest regions to the warm tropics, from deep-sea hydrothermal vents to coastal ecosystems; tracked the movements of fish and interrogated ...
Perspective view of the sea floor of the Atlantic Ocean and the Caribbean Sea. The purple sea floor at the center of the view is the Puerto Rico Trench.. Roughly 97% of the planet's water is in its oceans, and the oceans are the source of the vast majority of water vapor that condenses in the atmosphere and falls as rain or snow on the continents.
A mysterious "monster" fish with teeth washed up on shores of a California park in a "very rare" sighting on Friday, 13 October. Crystal Cove State Park posted images of the specimen on their ...
Altogether the ocean occupies 71 percent of the world surface, [4] averaging nearly 3.7 kilometres (2.3 mi) in depth. [27] By volume, the ocean provides about 90 percent of the living space on the planet. [4] The science fiction writer Arthur C. Clarke has pointed out it would be more appropriate to refer to planet Earth as planet Ocean. [28] [29]
