Record number: 1, Textual support number: 1 CONT
Water's unique temperature-density relationship results in the formation of distinct layers within nonflowing bodies of water ... During the summer, a surface layer (epilimnion) is heated by solar radiation and, because of its lower density, floats upon the bottom layer, or hypolimnion. This phenomenon is called thermal stratification. 3, record 1, English, - hypolimnion

Dans une mer ou un lac [...] l'eau est homogène sur l'épaisseur d’une «couche de mélange» ou «couche homogène», brassée par le vent. L'homogénéisation concerne principalement la température [...], et la base de cette couche est marquée par une couche en général peu épaisse, dite thermocline, au sein de laquelle la température rejoint rapidement celle des couches plus profondes. [...] Dans le vocabulaire de la limnologie, la couche homogène localisée au-dessus de la thermocline est appelée l'épilimnion; la couche sous-jacente(relativement homogène elle aussi), l'hypolimnion. Cependant, la structure de la masse d’eau est souvent plus complexe encore puisque dans les lacs profonds, et surtout en mer, il n’ est pas rare d’observer plusieurs thermoclines à des profondeurs successives, séparant des couches d’eau homogènes. 4, record 2, French, - couche%20de%20m%C3%A9lange

The transition layer between the upper water body (epilimnion) and the lower water body (hypolimnion) in a stratified lake is referred to as the "metalimnion," whereas if a single depth is to be reported to represent the division between layers, the section of highest temperature gradient with depth within the metalimnion is often employed, and may be referred to as the "thermocline." 3, record 3, English, - metalimnion
