Abstract
Ice conditions during mid-January 1974 in the Gulf of St. Lawrence and in the estuary as far upstream as Rimouski are described based on SLAR, IR and phot ographic imagery. The interpretations are verified by simultaneous surface ob servations on the ice by investigators operating from the CSS Dawson. The ice examined was undergoing rapid drift and deformation and showed a wide variet y of features typical of thin ice (0-40 cm) that has formed under the influen ce of strong winds and currents. These observations should serve as a guide to imagery interpretation in other similar ice areas where ground truth is not available.
