Deepwater, английский
Water sufficiently deep that surface waves are little affected by the ocean bottom. generally, water deeper than one-half the surface wave length is considered deepwater.
Deepwater circulation, английский
Movement below the upper layer influenced by surface currents is driven by density (a function of temperature and salinity) and by gravity which pulls the water downhill into ocean basins. these currents, which flow under the surface of the ocean, hidden from immediate detection, are sometimes called submarine rivers, but are properly named thermohaline circulation (thermo = heat, haline = salt), or meridional overturning circulation, or density-driven circulation. over a very long period of time, thermohaline circulation mixes the waters of all the oceans and turns them into a global system. it is this system that climatologists fear may be impacted by global warming and alter worldwide climates (see argo). popularly described as the “great oceanic conveyor belt,” it originates in the north atlantic where evaporation increases the salinity and hence the density of surface water, which is also cooled by water from the arctic ocean. sinking to the abyssal plain, it moves south along the coasts of the americas to antarctica, where it joins another deep current caused by evaporation in the drake passage off the southern tip of south america. this dense water then splits into two streams that cross the indian ocean and resurface in the pacific about 1200 years later. the colder, denser water eventually warms and returns to the surface layer.
Deepwater layer, английский
The water between the thermocline and the sea floor, representing some 90 percent of all ocean water. it is extremely cold (close to 0°c), non-circulating, and almost devoid of oxygen. nevertheless, recent studies show that it houses a wide range of living creatures and organisms. also called the hypolimnion.
