"The Canadian Ice Distribution Survey of the Geographical Branch has been collecting data on conditions of sea, lake and river ice for more than a decade. In addition the Branch has developed a program of glaciology during this period. This paper is related to both of these programs. It forms part of a study of ice conditions in the Canadian Prairies section of the Nelson River drainage system. It is a statistical treatment of break-up and freeze-up data in which hydrological and meteorological observations are related to river-ice conditions. The areal variability and rate of progress of ice formation and disintegration are analysed and mapped"--Preface. Issued also in print format. Includes abstracts in English and French.
