Related to thermocline: halocline


1. An intermediate layer of oceanic water in which temperature decreases more rapidly with depth than in the layers above and below it.
2. A layer in a large body of water, such as a lake, that sharply separates regions differing in temperature, so that the temperature gradient across the layer is abrupt.


(Physical Geography) a temperature gradient in a thermally stratified body of water, such as a lake


(ˈθɜr məˌklaɪn)

a layer of water in an ocean or certain lakes, where the temperature gradient is greater than that of the warmer layer above and the colder layer below.

2], with or without parameterization, since there was no thermocline.
The story begins with Henry and Aria Lindstadt on a honeymoon diving trip in the Bermuda Triangle finding a thermocline, which is the passage to another dimension.
However during the summer, when the lake was stratified, sedimentation rates in traps below the thermocline were essentially constant and less than fluxes in the uppermost trap.
The thermocline is also a stable pycnocline, a zone where water density increases with depth in response to changes in temperature and that, for precisely this reason, can be crossed by internal waves.
Thus there is a layer of ocean in which the sound, reflected in turn between the thermocline and the zone of increasing pressure, can travel for a significant distance.
Many animals, driven to maintain a constant body temperature, live within a certain thermocline, avoiding others.
The most common approach is to improve the initial ocean conditions by assimilating observations of sea surface temperature, thermocline (region of rapid temperature decline) depth, or sea level into an ocean model prior to coupling it with an atmosphere model.
The tailings are discharged below a thermocline and, being deaerated, the tailings will not diffuse.
Due to its shallow depth, one of the lakes (Lake Abborrtjarn 2) has only a weak thermocline.
But the thermocline rose rapidly during May and June in the eastern Pacific, says Kousky.
A larger density difference between the cold water and warm water in the storage tank will result in a thinner thermocline allowing a higher figure of merit (FOM), which is used as a measure of the amount of cooling available from the storage tank.
