All-weather ice information system for Alaskan Arctic coastal shipping

The paper describes an all-weather, near real-time ice information system designed to aid arctic coast shipping along the Alaskan North slope during August and September, 1976. The system utilizes an x-band "side looking airborne radar" (slar) mounted aboard a U.S. Coast Guard "HC-130B" aircraft. The requirements that an ice information system must meet are then summarized.
