This dataset contains visual assessments and passive observations of North Pacific sei, humpback, and gray whales collected from the research vessel Yushin-Maru No. 2 in the North Pacific Ocean and Gulf of Alaska. The cruise had four main objectives: (a) information for the ongoing assessments of North Pacific sei, humpback and gray whales in terms of abundance, distribution and stock structure; (b) information on the critically endangered North Pacific right whale (NPRW) population in the eastern North Pacific; (c) baseline information on distribution, stock structure and abundance for a poorly known area for other cetacean species/populations, including those that were known to have been depleted in the past but whose status is unclear; (d) essential information for the development of the medium-long term international program in the North Pacific to meet the Commission’s long-term conservation and management objectives.
