Abstract
Abstract During January and February 1978, six ADRAMS (Air Deployable Random Access Measurement System) ice buoys were dropped by parachute onto five icebergs, four in the vicinity of Cape Dyer, Baffin Island, and one northwest of Disko Island on the west coast of Greenland. These ice buoys transmitted a signal to the NIMBUS-6 satellite which could be used to compute position and local temperature. The ice buoys were tracked for periods which ranged from 138 days up to 202 days. The four icebergs along the Baffin Island coast were aground from 8% to 88% of the time observed. Maximum daily average speeds ranged as high as 0.60 m/s while modal speeds were generally less than 0.15 m/s. The drifts were generally coastwise in a southerly direction. The iceberg near Disko Island was aground 25% of the time observed and had a maximum daily average speed of up to 0.20 m/s with a modal value of between 0.05 to 0.10 m/s. The drift of this iceberg began erratically with the final 40 days strongly offshore toward the west.
