Large amounts of measurements in space and time are always needed to give reliable estimates of mixing in a water body. One particular interest of this work concerns a dense survey of temperature microstructure at different times of year. This enables testing of the characteristics of the turbulence weather in the hypolimnion of the lake. 1, record 1, English, - temperature%20microstructure

In the oceans, this zone of rapid temperature change starts at 10–500 m below the surface and can extend down to more than 1500 m.... In thermally stratified lakes in summer the thermocline separates the warm surface waters(epilimnion) from the cooler deep waters(hypolimnion). 3, record 2, English, - thermocline

Record number: 3, 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 3, English, - hypolimnion

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.

... it was necessary to examine the magnitude of the increase in phosphorus loading to the lake. In this regard, several important factors such as phosphorus loading from other sources, flushing rate of the lake, capacity of the shoreline soils to bind phosphorus, and so on, required investigation. It was recognized that the critical link between phosphorus levels and effects on the trout population was the oxygen level(or more correctly, the oxygen deficit) in the hypolimnion. This oxygen level could be translated into carrying capacity for trout which determined the maximum trout biomass that could be supported by the lake. 2, record 5, English, - oxygen%20content
