Description: The BWHALE_VOL2 depicts known beluga whale habitat areas in four environmentally sensitive areas along the Southcentral coast of Alaska. This data was digitized from mylar original maps from the Alaska Habitat Management Guides (1986), special areas management plans and updated bluelines from area biologists (1997) and updated in 1999 (Matt Eagleton,National Marine Fisheries Service). Data for the following categories were captured: Known spring/summer/fall concentration areas: Areas where concentrations of beluga whales have been observed during more than one year (assumed feeding) Data exists only for those 1:250000 quads that contain four specific sensitive areas identified as MESAs with beluga whale data; data are not continuous along the coast. For a complete list of MESA areas with beluga whale data please see the metadata section on data quality.
