As one descends from the surface of the ocean, the temperature remains nearly the same as it was at the surface, but at a certain depth temperature starts decreasing rapidly with depth. This boundary [..]

level or layer of a fluid depth where temperature changes more rapidly than the fluid either above or below it.

A vertical temperature gradient, in some layer of a body of water, that is appreciably greater than the gradients above and below it; also a layer in which such a gradient occurs. The permanent thermo [..]

a boundary marking a vertical change in temperature.

The boundary layer separating the near-surface warm waters from the colder, deeper layers of a body of water. Water temperature changes rapidly with depth within this layer. In the ocean, the thermocl [..]

Layer of water separating upper warmer and lighter water from lower colder and heavier water in a lake or sea; a stratum of abrupt change in water temperature. thermoconformer

A distinct layer of water where rising warm and sinking cold water meet but do not mix. It is a layer of water where the temperature changes at least one-half a degree per foot of depth. In many of ou [..]

area of rapid temperature change in the ocean. 

The layer of maximum vertical temperature gradient in the ocean, lying between the surface ocean and the abyssal ocean. In subtropical regions, its source waters are typically surface waters at higher [..]

a layer of water in an ocean or certain lakes, that separates warmer surface water from colder deep water. Temperature rapidly changes with depth in this region of the water column.

Depth zone within which temperature changes maximally

A layer in the ocean in which temperature changes rapidly with depth. This often occurs in the area directly below the ocean surface layer that is most warmed by the sun and well-mixed by wind-derived energy.

 Zone between the colder water of the ocean depths and warmer surface water. Large temperature variations occur with depth in the thermocline zone. Near the surface, however, where water is always in motion, and in the ocean depths where there is no source of heat, the water temperature is fairly uniform.  

A transition layer of water in the ocean, with a steeper vertical temperature gradient than that found in the layers of ocean above and below. The permanent ther- mocline separates the warm mixed surface layer of the ocean from the cold deep ocean water, and is found between 100- and 1000-m depths. The thermocline first appears at the 55 - 60 degre [..]

A thermocline is a region in the ocean with a strong temperature gradient. Oceanographers usually make a distinction between the seasonal thermocline (which is formed at the base of the summer mixed l [..]

The region separating the uppermost part of the ocean, whose waters are well mixed, from the colder deep ocean, where mixing is reduced and temperature changes are much slower to occur. Roughly 90% of [..]

Zone between the colder water of the ocean depths and warmer surface water. Large temperature variations occur with depth in the thermocline

A layer of water characterised by rapid changes in temperature  - separating the upper 'mixed-layer' of the ocean from the cooler deep water layer - both of which have generally little relat [..]

The middle layer of a thermally stratified lake or reservoir. In this layer, there is a rapid decrease in temperatures in a lake or reservoir.

The middle layer of a thermally stratified lake or reservoir. In this layer, there is a rapid decrease in temperatures in a lake or reservoir.

A layer in a body of water in which the water temperature changes rapidly with depth relative to the layers of water above and below.

The middle layer in a thermally stratified lake or reservoir. In this layer there is a rapid decrease in temperature with depth. Also called the METALIMNION.

An area in the ocean where there is a distinct change in the water temperature as you change depth.

A transition layer of water in the ocean, with a steeper vertical temperature gradient than that found in the layers of ocean above and below. The permanent thermocline separates the warm mixed surfac [..]

The middle layer in a thermally stratified lake or reservoir. In this layer there is a rapid decrease in temperature with depth. Also called the metalimnion.

Boundary in a body of water where the greatest vertical change in temperature occurs. This boundary is usually the transition zone between the layer of warm water near the surface that is mixed and the cold deep water layer

A temperature gradient within layer of a body of water that is notably greater than the temperature gradients above and below it.

As one descends from the surface of the ocean, the temperature remains nearly the same as it was at the surface, but at a certain depth temperature starts decreasing rapidly with depth. This boundary is called the thermocline. In studying the tropical Pacific Ocean, the depth of 20ºC water ("the 20ºC isotherm") is often used as a proxy fo [..]

fairly thin zone in a lake that separates an upper warmer zone (epilimnion) from a lower colder zone (hypolimnion).

The ocean phenomenon characterised by a sharp change in temperature with depth

A vertical temperature gradient in a water body appreciably greater than gradients above or below.

The layer of the water in a lake that lies between the epilimnion and the hypolimnion.

A vertical negative temperature gradient in some layer of a body of water which is appreciably greater than the gradients above and below it. In the ocean, this may be seasonal, due to the heating of the surface water in the summer, or permanent.

A vertical negative temperature gradient in some layer of a body of water which is appreciably greater than the gradients above and below it. In the ocean, this may be seasonal, due to the heating of the surface water in the summer, or permanent.

The region in the worldÕs ocean, typically at a depth of 1 km, where temperature decreases rapidly with depth and which marks the boundary between the surface and deep ocean.
