Description:

The Eastern Bering Sea (EBS) beluga (Delphinapterus leucas) stock inhabits the waters of Norton Sound and the Yukon River Delta, Alaska, during the ice-free period from spring sea ice breakup to autumn freeze-up. During June, July, and August, belugas aggregate near the Yukon River Delta, where they feed on seasonally abundant salmon (Oncorhynchus spp.). EBS belugas are an important nutritional and cultural resource to Alaska Natives, and are harvested by more than 20 communities in Norton Sound and the Yukon. To collect data for an updated abundance estimate for EBS belugas, aerial line-transect surveys were conducted in Norton Sound and off the Yukon River Delta from 16 through 29 June 2017. During the 14-day survey period, 16 survey flights were conducted on 12 days, covering more than 8,500 km of transect effort.
