This database contains counts of Steller sea lion pups on rookeries in Alaska made between 1961 and 2015. Pup counts are conducted in late June-July. Pups are counted from the ground (by walking along the rookery), from cliff-side overlooks, and from aerial images (oblique and vertical orientation). Pup counts conducted in late June-mid July are considered to represent a complete census of pups produced at each site during the year.
