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.

(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.

These pelagics tend to school throughout the year with the largest schools forming during the cool months when a thermocline is not present.
The freshwater runoff from the river outflow increases the vertical salinity gradient within the ocean temperature mixed layer and suppresses turbulent heat flux from the ocean's thermocline to the sea surface, creating a "barrier" of heat exchange between these layers.
distinguenda was the dominant species at two stations in the Costa Rica Dome, with greatest concentrations at between 250 and 450 m during the day and night, but with an abundance peak at night above the thermocline (10-50 m).
The research, to explore what may be a deeper section of the Marianas trench, concealed by a thermocline cloud of hydrogen sulphide,is being funded by billionaire Jack Morris (Rainn Wilson).
A strong thermocline develops this time of the year and most fish hover just above it.
Apparently, there is what is called a thermocline, a layer in a body of water that separates different kinds of water temperature, a sort of thermal stratification.
Swordfishes are found in all tropical, subtropical, and temperate oceans of the world from the surface to depths of at least 610 m (2000 ft; Taylor and Murphy 1992), but are generally found above the thermocline, preferring temperatures of 18-24[degrees]C (Collette 1995).
In addition to annual migrations that may span thousands of kilometers in a single season, swordfish also exhibit daily vertical movements that transition from surface waters at night to those below the thermocline during the day (300-1,000 m; Carey and Robison, 1981; Carey, 1990; Sepulveda et al., 2010; Dewar et al., 2011).
In the discharge mode of the storage tank, cold water is drawn from the bottom of the tank, and warm water is returned to the top of the tank, at the design flow rate of the diffusers (low enough not to interrupt the thermocline).
There's nothing like seeing a raptor effortlessly circling on a thermocline. Shame we don't have the golden eagles and harriers in our region.
The eddies establish the formation of thermal and saline fronts and gradients as well as depth of the thermocline and mixed layer (Trasvina et al., 2003; Zamudio et al., 2006; Trasvina & Barton, 2008), which represent physical borders or advective mechanisms that shape and modify spatial patterns of species abundance (Moreno et al., 2009).
