Summary

This data set provides monthly (March–October) gridded density estimates for seabirds in lower Cook Inlet, Alaska. Gridded density estimates were produced by applying spatiotemporal modeling of at-sea survey data collected between 1975 and 2021 of seabird at-sea surveys available in the North Pacific Pelagic Seabird Database (NPPSD; Drew and Piatt 2015). We modeled joint dynamic species distributions of dark shearwaters (Ardenna spp., including A. grisea and A. tenuirostris), black-legged kittiwake (Rissa tridactyla), common murre (Uria aalge), pigeon guillemot (Cepphus columba), Kittlitz’s murrelet (Brachyramphus brevirostris), marbled murrelet (B. marmoratus), horned puffin (Fratercula corniculata), and tufted puffin (F. cirrhata).
