Description
Summary: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 were taken simultaneously at four stations every hour to measure the character and change of the thermal microstructure in the water. At the same time, acoustic pulses were transmitted from one station to another to determine the effect of the thermal microstructure on acoustic propagation. Two 1-week cruises across the Chukchi Sea were made, one before and one after the ice floe occupancy, to study the intrusion of warm Pacific water which occurs every summer and to measure acoustic scattering from biological layers. Sponsored in part by DARPA.
