Preliminary results of a binational research cruise in the Western Arctic Ocean

Abstract

This paper is a condensed version of a report on the preliminary results of a research cruise under the direction of the U. S. Geological Survey, on board the United States Coast Guard Cutter Polar Star to Northwind Ridge and Canada Basin of the Western Arctic Ocean, during the period August 16‐September 15, 1993. Major objectives of the cruise were to: survey the geology of the North‐wind Ridge and Canada Basin; determine whether radionuclide contamination from disposal of solid and liquid nuclear wastes by the former Soviet Union in the Kara and Barents seas had penetrated the North American Arctic; acquire sediment cores in support of research on the history of glaciation in the region; and gain a better understanding of water structure and currents, sea‐ice physics, and sediment and nutrient transport.
