Seasonal variability of thermal regime in a shallow ice covered lake

Maher, OA and Malm, Joakim LU (2003) In Nordic Hydrology 34(1-2). p.107-124
Abstract
A systematic study was conducted over six years (1994-1999) on a shallow ice covered lake in the Russian Republic of Karelia with the aim of developing better understanding of some physical processes occurring in shallow ice-covered lakes. The average ice-covered period was 182 days while the longest ice-covered period was 193 days. The average lake water temperature at ice formation was 0.5-10degreesC, while the average water temperature just before ice break-up was close to 4degreesC. The heat flux from water to ice was low during early winter but could increase above 5 Wm-2 (daily average) during the last month before ice break-up. The heat flux from sediment to water was the main source of heat to the water body during early to mid... (More)

The heat flux from water to ice was low during early winter but could increase above 5 Wm-2 (daily average) during the last month before ice break-up. The heat flux from sediment to water was the main source of heat to the water body during early to mid winter being about 2-6 W.m-2 during early winter but decreasing to about 1-2 Wm-2 during early spring.
