Description: Special Report
Abstract: This seventh in a series of reports on lake and river ice and land-fast sea ice presents ice thickness measurements observed throughout the North American Arctic and subarctic during the 1970-71 and 1971-72 winter seasons. Information on surface ice conditions, dates of first ice, freeze-over and breakup, and detailed measurements of ice thickness across Alaskan rivers are also included. Some reports from the Alaska National Guard network on ice thickness measurements in remote areas of western Alaska are also presented Analyses were made of maximum observed ice thicknesses reported during the two winters, and deviations from the mean ice thickness measured across rivers. and creeks in southeast Alaska between 1965 and 1972. A tabulation of the dates when maximum ice was observed at 25 locations in Alaska, 44 in Canada and 1 in Greenland during each year from 1961 to 1972 is also given. Computations of the average annual date of maximum ice at all the stations and an isoline map showing the results for northern North America is presented.
