Description
Summary:The subsatellite experiment “Thermal Front in Lake Ladoga, 2010” and its results are described. The experiment was performed at the initial stages of thermal bar existence at the end of May 2010. We estimated the horizontal gradients of water temperature and the front motion rate by two successive surveys carried out with a discreteness of four days. Cumulative heat flows coming to the lake surface were different on different front sides. The hydrochemical and hydrobiological parameters of the front zone were not characterized by any significant horizontal differences.
