Description: Special Report
Introduction: The first report in this series (Bilello, 1961) describes the initiation and expansion of the ice thickness measurement network in Canada. By May of 1960, 30 locations throughout Canada were providing complete records and four stations in Alaska and Greenland were providing partial records. In the first report the ice measuring equipment and observational procedures were described, ice thickness measurements from 1958 to 1960 were tabulated, and isoline maps of maximum observed ice thicknesses for this period were presented. Ryder (1954) conducted a study on ice thickness in the Northern Hemisphere, in connection with construction and maintenance of airdromes on ice. His report contained a comprehensive bibliography on lake and river ice, a tabulation of ice thickness data from North America, and brief records on ice thickness for 41 stations in the U. S., 38 stations in Canada (only 6 of which were North of 54° N latitude), and 6 stations in Alaska. Attention was directed to the fragmentary nature of the little ice data available, and the need for a planned program for ice thickness observations was stressed. Williams (1963), using the data in Ryder's study and recent records of ice thickness in Canada, developed probability charts for predicting ice thickness on a regional basis. The charts can be used to obtain a reasonable estimate of the probable rate of ice growth and ice thickness in Canada, and to relate maximum ice thickness to the length of the period of ice growth. This second report prepared by USA CRREL is a continuation of the current observational program and presents data on ice thickness during the 1960-61 and 1961-62 seasons. The network has been expanded to Alaska during this period and some station changes have taken place. These changes are discussed and some supplemental ice thickness data for two stations on the east coast of Greenland are presented. The data are presented in their original form, as was done in the previous report, in order to make them fully available to potential users. Analysis has been limited to a study of maximum ice thicknesses.
