Mixed layer and thermocline
WebA thermocline is a lean but separate layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which warmth changes further quickly with depth than it does in the layers above or below. It is the change sheet between warmer mixed water at the ocean’s exterior and cooler deep water below. In the ... WebThis bathy's mixed layer and thermocline are clearly defined and are typical of warmer ocean regions. Figure 1a. Typical Eastern Pacific winter bathythermograph. Figure 1b. Sound velocity profile corresponding to the bathy shown in Fig 1a. In Fig 1 the isothermal layer extends down about 75m.

Web…the upper mixed layer (epilimnion) and the deep portion of the lake (hypolimnion). In shallow lakes or shallow portions of large lakes, the thermocline will eventually intercept the lake bottom so that no hypolimnion exists. Normally, as the heating season progresses, the thermocline intensifies and deepens. Secondary thermoclines may ...

Webthermocline: [noun] the region in a thermally stratified body of water which separates warmer surface water from cold deep water and in which temperature decreases rapidly with depth. WebIn addition to the thermocline stratification, the depth of the mixing layer (ML) and the presence of barrier layers (BL) are other key factors governing the seasonal flux of heat content...
WebSynoptic distributions of thermal surface mixed layer and thermocline were identified using four airborne expendable bathythermograph (AXBT) surveys (Septe Synoptic … Web22 dec. 2024 · In shallow, tidally energetic shelf seas, there can be two turbulent mixed layers, the surface mixed layer and the bottom mixed layer, separated by a thermocline. At a station in the western English Channel in August 1999, Sharples et al. (2001) found such a region with a thermocline at ~30 m.
Web1 nov. 2024 · At the simplest, macroscale level, these include, in oceans (lakes), a surface mixed layer (epilimnion), thermocline (metalimnion) and deeper, generally more quiescent layers (hypolimnion). This macroscale, three-layer structure is the classic example of a relatively strongly-stratified layer being found between two relatively well-mixed layers.
