Deepwater layer
| Морской словарь |
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.

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.

Lay, английский
- Position on the ground where a tree will fall when severed from the stump (10).
- The distance along a cable occupied by one complete helix of a strand or conductor. the direction of lay (left or right hand) is the direction of the helix looking away from an observer. also to arrange the wires or members of a conductor either by twisti
- To come and go, used in giving orders to the crew, such as "lay forward" or "lay aloft". to direct the course of vessel. also, to twist the strands of a rope together. to make it to a mark, buoy, or harbor, such as "we will lay the mark".
- [1] to aim a gun. [2] to plan a ship’s course. [3] to place a vessel in a specified position (e.g., lay alongside). [4] to order a person to go to a specific location (e.g., lay aloft, or lay below). [5] to drop an anchor. [6] to place strands together ready to be twisted into rope. [7] to twist the strands to form a rope. [8] the direction in which the strands have been twisted (see rope & hawser lay). lay aloft!: command for topmen to climb to their stations.
Lay (laid, laid), английский

Lay a gun, to, английский
So to direct it as that its shot may be expected to strike a given object; for which purpose its axis must be pointed above the latter, at an angle of elevation increasing according to its distance.

Lay boat, английский
A boat anchored for some specific purpose, such as marking a location. lay-by: a place where vessels can anchor away from traffic and out of the current.
Lay crossties, английский
Thermocline, английский
A transition layer of varying thickness forming a temperature gradient between the relatively warm epilimnion (mixed or surface layer) and the much colder hypolimnion (deep water layer). the thermocline varies with latitude and season, being permanent in the tropics and almost absent at the poles.
Circulating, английский
Nevertheless, английский
Тем не менее
Hypolimnion, английский
The lowest of three layers of sea water. see deep water layer.
