The cold, deepest layer of a lake that is removed from surface influences (Gr. hypo under, limne lake).
The hypolimnion is the lower layer of a lentic (standing water) ecosystem
The bottom layer of lake water during the summer months. The water in the hypolimnion is denser and much colder than the water in the upper two layers.
lower layer of water in a lake.
the part of a lake below the thermocline made up of water that is stagnant and of essentially uniform temperature except during the period of overturn
The deep cold layer of a lake lying below the metalimnion (thermocline) during the time a lake is thermally stratified. See also epilimnion, metalimnion. [Gk. hypo, under + limne, lake.
The layer of water below the thermocline in a fresh water lake, as opposed to the epilimnion.
The lowermost, non-circulating layer of cold water in a thermally stratified lake; usually deficient of oxygen.
The lowest layer in a thermally stratified lake or reservoir. This stagnant layer of colder, more dense water, has a constant temperature.
The bottom, and most dense layer of a stratified lake. It is typically the coldest layer in the summer and warmest in the winter. It is isolated from wind mixing and typically too dark for much plant photosynthesis to occur.
The colder, dense, deep water layer in a thermally stratified lake, lying below the epilimnion and metalimnion, and isolated from surface influences.
Stratification is the layering of water due to differences in density. 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. The cold bottom water is the hypolimnion.
Bottom waters of a thermally stratified lake. The hypolimnion of a eutrophic lake is usually low or lacking in oxygen.
The cold stagnant deep-water layer of a lake.
In a lake, the layer of cold, dense waters extending below a depth of 15'-30'. Separated from the warm, oxygen-rich water of the epilimnion by the thermocline and only mixing during spring and fall turnover.
The layer of water in a thermally stratified lake that lies below the thermocline, is noncirculating, and remains perpetually cold.
The layer of water below the thermocline in a freshwater body.
The hypolimnion is the bottom and most dense layer of water in a thermally-stratified lake. It is the layer that lies below the thermocline. Typically, it is non-circulatory and remains cold throughout the year.
