| Experiments were conducted in the epilimnion of a high-UV system at midday and in late afternoon. |
|
| The sampling depth of 1.5 m was near the midpoint of the epilimnion depth in each lake. |
|
| Further, on two dates we also measured Secchi depth and oxygen concentration in the epilimnion of each enclosure during midday. |
|
| The chemistry of the two parts of a freshwater lake, the epilimnion and the hypolimnion, is affected by biological processes and by circulation. |
|
| The mean acoustic size of rising bubbles decreased in the hypolimnion but increased in the epilimnion. |
|
| The amount of bacterial cells imported via the inlets in relation to bacterioplankton cells produced in the epilimnion of the lakes was also determined. |
|
| In a stratified lake, carbon, nutrients, and silica are extracted from the epilimnion during photosynthesis. |
|
| Secondary thermoclines may develop in the epilimnion, and these will migrate downward to the main seasonal thermocline. |
|
| Water samples were taken from the epilimnion and hypolimnion in the deepest portion of the lake using a Kemmerer sampler. |
|
| In summer the water of many lakes becomes stratified into a warmer upper layer, called the epilimnion, and a cooler lower layer, called the hypolimnion. |
|
| When a lake is thermally stratified, volume-weighted epilimnion, metalimnion and hypolimnion samples are collected in addition to the whole-lake sample. |
|
| Decreased concentrations of inorganic carbon in the epilimnion, resulting from increased rates of photosynthesis, are responsible for the precipitation of calcium with bicarbonate. |
|
| The lake was stratified throughout the summer, with the boundary between the epilimnion and the hypolimnion at a depth of 1 to 2 meters. |
|
| This process leads to reduced concentrations of nitrate, phosphate, and silica in these waters and, during times of maximum daylight organic production, supersaturation of epilimnion waters with respect to dissolved oxygen. |
|
| The warm layer is called the epilimnion and the cold layer is called the hypolimnion. |
|
| Finally, overlying the metalimnion is a surface layer of a warmer, lighter water is called the epilimnion. |
|
| In case of a difference in salinity, the hypolimnion and epilimnion are separated not by a thermocline but by a halocline, which is sometimes referred to as a chemocline. |
|
| Expressed more technically, the mere consists entirely of the epilimnion. |
|
| In August and September the ORP decreased to about 350 mV in the epilimnion, increased in the metalimnion to almost 400 mV, and remained at that level down to the bottom. |
