Lake Turnover: Seasonal Nutrient Cycling in Lakes
Turnover is a phenomenon that occurs in terrestrial bodies of water, such as lakes and ponds, in which the water near the surface of the lake (epilimnion) is replaced with the water near the bottom of the lake (hypolimnion) to establish a homogenous mixture. Lake turnover occurs during both the fall and spring when the thermocline (temperature gradient relative to lake depth) is nearly uniform throughout the lake. (more…)
