Usage: Scientists call the transition zone between balmy surface water of a lake and the cold deep water region "metalimnion." Also called thermocline. thermocline: a boundary layer, found in lakes or enclosed seas, between warm upper water and cooler lower water, that is usually maintained only under calm conditions in summer. In the thermocline, temperature decreases rapidly from the mixed upper layer of the ocean (called the epipelagic zone) to much colder deep water in the thermocline (mesopelagic zone). a comic character, usually masked, dressed in multicolored, … RELIGIONS With the onset of autumn, the epilimnion cools and the water becomes denser, sinking and mixing with the hypolimnion. Typically stratified lakes show three distinct layers, the Epilimnion comprising the top warm layer, the thermocline (or Metalimnion): the middle layer, which may change depth throughout the day, and the colder Hypolimnion extending to the floor of the lake.
