This report includes data from two efforts to satellite tag beluga whales. The first was conducted by the Alaska Beluga Whale Committee (ABWC) through NOAA grant NA67FX0197, the Alaska Department of Fish and Game (ADF&G), the National Marine Fisheries Service (NMFS), the North Slope Borough (NSB), and the Village of Point Lay. This was the first time belugas in Alaska were instrumented with satellite tags. Ten belugas were tagged in 1998-1999. The second took place in 2000-2002. It was initiated by the ABWC and further supported by Minerals Management Service (MMS) through the Coastal Marine Institute. Other cooperators included NMFS, ADF&G, the NSB, the Village of Point Lay, and Alaska Marine Ecosystems Research.
