2012: In January 2012, "Healy" escorted the Russian-flagged freighter "Renda" through pack ice to deliver an emergency supply of fuel to Nome, Alaska. Such a winter delivery had never been attempted before because the ice floes are thick during the winter season. The resupply was vital to the city, and was the first-ever winter fuel delivery from the water in Western Alaska. Over the course of Arctic West Summer 2012 (AWS12), "Healy" travelled over and conducted 687 science casts. "Healy" also added 25% more data to the bathymetric mapping project of the extended continental shelf through multibeam sonar bottom-mapping. This data was collected in support of the delineation of the American and Canadian continental shelves.
