| Abstract: | Thermodynamic processes of lake ice in three lakes and landfast sea ice around Zhongshan Station,east Antarctica were investigated in 2006.The growth and decay processes of lake ice were compared with those of landfast sea ice on the basis of in situ data.The responses of lake-ice and landfast sea-ice temperatures at varying depths relative to the time series of the local surface air temperature were explored.The vertical conductive heat fluxes at varying depths of lake ice and sea ice were derived from the... |
