Abstract

USCGC Healy cruise 1803 took place from 25 October to 18 November 2018, departing from and returning to Dutch Harbor, AK. The cruise was part of the project entitled “Monitoring the Western Arctic Boundary Current in a Warming Climate: Atmospheric Forcing and Oceanographic Response”, funded by the National Science Foundation as part of the Arctic Observing Network. The purpose of the cruise was to service the long-term mooring deployed in the Pacific Arctic Boundary Current on the continental slope of the Alaskan Beaufort Sea. In addition to recovering and re-deploying the mooring, the other primary objective of the cruise was to collect hydrographic measurements to further our understanding of the nature of the boundary current and its downstream evolution. A number ancillary projects were also carried out by independent investigators taking advantage of a ship of opportunity.
