| Abstract | The prediction or the annual runoff to be expected from snow covers and glaciers, of the rate of ice growth under various conditions or the maximum ice thickness to be expected at a given site, are problems of particular interest to Canadians. Consideration of these problems has resulted in a growing interest in the exchange of heat between the atmosphere and snow and ice covers. Because the period of interest is usually winter, the time when this heat exchange is at a minimum, the accur.ate measurement of some components or the exchange is very difficult. Observations are often undertaken without an appreciation of the magnitude of the quantities to be measured, the difficulties or measuring such quantities in winter and the limitations of instruments and techniques now available. In response to the growing interest in the heat exchange and snow and ice surfaces, and the need for information on measuring this exchange, the Snow Bnd Ice Subcommittee of the Associate Committee on Soil and Snow Mechanics sponsored a one-day conference at which the results and experience of those making observations could be presented and discussed. Information was presented on the heat exchange at the surface of snow covers, fresh water and sea ice and glaciers, as well as on instruments used in making measurements and some of their limitations. The papers presented at the conference, or a summary of those published elsewhere of those published elsewhere, and the ensuing discussion, are presented in this proceedings. |
