"As part of the Canadian Ice Distribution Survey, the Geographical Branch has been collecting data on the condition and distribution of sea ice. This report is the result of the second ice reconnaissance survey carried out during the summer of 1957 when the northern supply ship C. G. S. d'Iberville made her annual voyage to the Eastern Arctic. The report of the 1957 ice reconnaissance survey is published to provide a picture of the nature, conditions and distribution of the ice encountered by Canadian Government ships on their annual re-supply mission. Its purpose is to record the special problems that ice presents to the ships engaged in this work in Canada's Eastern Arctic waters"--Preface. Issued also in print format. Sea ice Canada, Northern.
