Maximum Thickness and Subsequent Decay of Lake, River and Fast Sea Ice in Canada and Alaska
Weekly measurements of the thickness of lake, river and fast sea ice made over a period of 10 to 15 years at 66 locations in Canada and Alaska are analyzed, and the portion of the data relating to maximum ice thickness and decay (i.e. the decrease in ice thickness) is examined. Ice thickness curves...
