Heat flow density measurements in the sediments of three lakes in northern Sweden

Abstract [en]

Heat flow density measurements in the sediments of three lakes, 36 m, 73 m and 99 m deep, were carried out during a period of 3-5 years. The gradient measurements were made from ice during the winter season with a Bullard-type probe with nine thermistors 0.5 m apart. The thermal conductivity was measured in situ. Corrections were made for the disturbing temperature wave in the horizontally stratified sediments caused by seasonal variations in the bottom water temperature. It is clearly shown that the differences in bottom water temperatures between different years can be fully corrected only by very long time series. The heat flow density values obtained are compared with measurements in boreholes and they seem to be correct to within 20-30%
