Abstract : Detailed wind and temperature profiles up to a height of 4 meters have been obtained at 30-sec intervals for a period of 20 days in March 1970 from an ice field drifting in the Gulf of St. Lawrence in Canada. Wind speeds were measured with fast-response cup anemometers at heights of 37.5, 50, 100, 200, and 400 cm, and temperatures were measured with shielded copper constantan thermopiles at heights of 12.5, 25, 50, 100, 200, and 400 cm above the ice surface.
