Examples
-
They found synchronous changes in lake biota and sedimentological parameters that seemed to occur in parallel with the increasing mean annual and summer temperatures starting around the 1850s, and hypothesized that the rising temperature had increased the metalimnion steepness and thermal stability in the lake, which in turn supported increasing productivity by creating more suitable conditions for the growth of plankton.
Historical changes in freshwater ecosystems in the Arctic 2009
-
Nitrite (NO2) rarely accumulates except in the metalimnion and hypolimnion of eutrophic lakes.
-
The resulting positive heterograde oxygen curve is usually caused by extensive photosynthetic activity by algae in the metalimnion.
-
The metalimnetic oxygen maximum distribution occurs when the oxygen content in the metalimnion is supersaturated in relation to levels in the epilimnion and hypolimnion.
-
During the stable summer strati fi cation period the 30-60 m every 2 m; 60-100 m every 5 m; 100-5 m from the epilimnion, metalimnion and hypolimnion are about 15, 20, bottom every 10 m; and from 5 m-bottom at least every 1 m and up to 120 m thick respectively, depending on the depth (Fig. 3).

(hypolimnion) and the transition layer (thermocline or metalimnion).
