Description
Summary:Radar backscatter measurements from sea ice during the fall freeze-up were performed from aboard the United States Coast Guard Icebreaker Polar Star as a part of the International Arctic Ocean Expedition (IAOE'91) in August-September, 1991. The US portion of the experiment took place on board the Polar Star and has been referred to TRAPOLEX'91 (Transpolar expedition) by some investigators. Before prematurely aborting its mission because of mechanical failure of her port shaft the Polar Star reached 84 degrees 57' N. latitude at 35 degrees E. longitude. The ship was in the ice (>50% coverage) from 14 August until 3 September and was operational for all but 6 days due to two instances of mechanical problems with the port shaft. The second was fatal to the ship's participation in the expedition. Prepared in cooperation with Ohio State University, Columbus, OH.
