These were collected by Cascadia Research and collaborators from the eastern North Pacific from 1975 through 2004 (data collection is continuing). The primary scope of this dataset includes waters off California, Oregon, and Washington from 1986 to 2004 which accounts for over 6,000 of the records. ... View entire text

Purpose: Data was gathered to document movements, population structure and abundance of blue whales in the eastern North Pacific (see Calambokidis and Barlow 2004, Calambokidis and Steiger 1997, Calambokidis et al. 1990).

SUPPLEMENTAL INFORMATION: Updated on March 30, 2006, expanding the dataset up to 2004.
