Research Abstract

In the observed results, the bottom layer of Lake Ikeda was under anoxic condition for 21 years from 1990 to 2010. In the middle of February 2011, when the mean air temperature from January to February decreased by 8°C, the lowest since 1987, vertical mixing due to surface water cooling occurred and consequently a uniform vertical dissolved oxygen (4.5 mg/L) profile was attained. The overturn was achieved for about 50 days during December to February. The lake water temperature and dissolved oxygen dynamics under the warming trends were investigated by the vertical one-dimensional numerical model. The numerical analysis reveals that 1984, 1986 and 2011, in which the values of lake stability index were negative, correspond to the years of the overturn.
