the upper waters (above the metalimnion) of a thermally stratified lake.
The top layer of a lake.
The warmer, well-lit surface waters of a lake that are thermally separated from the colder (hence denser), water at the bottom of the lake when a lake is stratified.
The uppermost, warm, well-mixed layer of a lake (Gr. epi on, limne lake).
The upper, wind-mixed layer of a lake. This water is turbulently mixed throughout at least some portion of the day and because of its exposure, can freely exchange dissolved gases (such as O2 and CO2) with the atmosphere.
The epilimnion is the freely circulating surface water of a lentic (standing water) ecosystem
In a lake, the layer of warm, oxygen-rich water extending from the surface to a depth of 15'-30'. Separated from the cold, dense waters of the hypolimnion by the thermocline and only mixing during spring and fall turnover.
Most lakes form three distinct layers of water during summertime weather. The epilimnion is the upper layer and is characterized by warmer and lighter water.
see " Stratification."
topmost layer of water in a lake.
the water layer overlying the thermocline of a lake
The uppermost, warmest layer of a lake when a lake becomes thermally stratified in summer. The epilimnion lies above the metalimnion (thermocline). See also metalimnion, hypolimnion. [Gk. epi, on + limne, lake.
The upper layer of water in a thermally stratified lake or reservoir. This layer consists of the warmest water and has a fairly uniform (constant) temperature. The layer is readily mixed by wind action.
The upper, warmer, lighter layer of water.
The layering of water due to differences in density is stratification. Water's greatest density occurs at 39 Deg.F (4 Deg.C). As water warms during the summer, it remains near the surface while colder water remains near the bottom. Wind mixing determines the thickness of the warm surface water layer (epilimnion), which usually extends to a depth of about 20 feet.
an upper layer of warm water with high levels of dissolved oxygen.
Upper waters of a thermally stratified lake subject to wind action.
The topmost and warmest layer of water in an unfrozen lake. The epilimnion also contains the most oxygen of any part of the lake.
The upper water layer in a stratified lake that is more or less uniformly warm in the summer
The layer of water above the thermocline in a freshwater body.
Epilimnion is the top-most layer in a thermally stratified lake, occurring above the deeper hypolimnion. It is warmer and typically has a higher pH and dissolved oxygen concentration than the hypolimnion.
