Counts of Steller sea lion pups collected from terrestrial, aerial, ship, and unoccupied aircraft surveys of rookeries and major haulouts in Alaska during the Steller sea lion aerial survey project from 1961-06-22 to 2019-07-04 (NCEI Accession 0128189)

As part of the Steller sea lion research project, the Alaska Fisheries Science Center (AFSC) conducted surveys of Steller sea lions in Alaska from 1961-06-22 to 2019-07-04. This dataset contains counts of Steller sea lion pups on rookery and haulout sites collected by observers from terrestrial, aerial, ship, and unoccupied aircraft surveys. Pups were counted from the ground (by walking along the rookery), from cliff-side overlooks, from near-shore vessels, and from aerial images. Pup counts conducted in late June-mid July are considered to represent a complete census of pups produced at each site during the year.
