Studies in the Marginal Ice Zone of the Chukchi Sea: Analysis of 1972 Data
The report is a summary and analysis of studies in the Marginal Ice Zone of the Chukchi Sea in 1972 by the Applied Physics Laboratory of the University of Washington. A camp on an ice floe was established and occupied for two weeks during the summer. Temperature profiles of the water under the floe...
