Fall Ice Drift in Nares Strait, as Observed by Sideways-Looking Airborne Radar

Abstract

From Sideways-Looking Airborne Radar (SLAR) imagery of sea ice obtained on three flights during the week of 19 to 26 Oct. 1976 it is possible to track floes throughout Nares Strait over periods of days and, on one occasion, hours. The data are interpreted in the light of available information on ice drift, winds, and currents. The results are believed to give a fairly typical picture of ice drift characteristics in periods of northerly air flow, which is the dominant pattern in this area. The suitability of the method for acquiring drift information in other areas is also demonstrated.
