Abstract: In Santala Bay, a small sheltered bay close to Hanko in the Gulf of Finland area in the Baltic Sea, ice properties were investigated during three winters from winter 1998-1999 to winter 2000-2001. Santala Bay freezes every winter and is in a coastal landfast ice region. Measurements include ice cover structure and evolution, ice temperature profiles, under ice water temperature profiles and currents and meteorological data. Heat flux from water through ice cover to atmosphere was calculated and how it was affected by different ice cover properties. Also ice surface albedo variations under different conditions were calculated from short wave radiation measurements.
