Nevertheless, and since ocean basins are interconnected, many oceanographers prefer to refer to one single ocean basin instead of multiple ones. Older references (e.g., Littlehales 1930) [4] consider the oceanic basins to be the complement to the continents, with erosion dominating the latter, and the sediments so derived ending up in the ocean ...
Ocean basin – geologically an ocean basin is a large geologic basin which is below sea level. Ocean currents – Oceanic currents can be divided into surface and deep ocean currents. Surface currents are generally wind driven and develop typical clockwise spirals in the northern hemisphere and counter-clockwise spirals in the southern hemisphere.
At such thickness, the SML represents a laminar layer, free of turbulence, and greatly affecting the exchange of gases between the ocean and atmosphere. As a habitat for neuston (surface-dwelling organisms ranging from bacteria to larger siphonophores), the thickness of the SML in some ways depends on the organism or ecological feature of interest.
A flat or very gently sloping area on the floor of a deep ocean basin. absolute dating The process of determining a specific date (in years or some other unit of time) for an archaeological, geological or paleontological site or artifact. accident A sudden discontinuity of ground, such as a fault of great thickness, bed or lentil of unstable ...
Ocean stratification is the natural separation of an ocean's water into horizontal layers by density. This is generally stable stratification , because warm water floats on top of cold water, and heating is mostly from the sun, which reinforces that arrangement.
Major continental divides, showing drainage into the major oceans and seas of the world. Grey areas are endorheic basins that do not drain to the ocean.. A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not ...
The following outline is provided as an overview of and introduction to Oceanography.. Thermohaline circulation. 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.
The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone.The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of ...
