Gridded Seabird Density Estimates in Lower Cook Inlet, Alaska
공공데이터포털
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). Together these species compose 77% of all birds counted on surveys in lower Cook Inlet

Data from the Capture and Collection of Non-Die-Off Seabirds Across Alaska
공공데이터포털
This data package contains one table with morphometric and diet information for "non-die-off" seabirds captured and collected in southcentral and southwest Alaska. Data pertains to birds captured (live) or collected (lethally) including, bird identification numbers, sampling dates, geographic locations, body measurements, diets (from either stomach contents or regurgitated prey), and sex and age of the bird when discernible. Common Murres (Uria aalge) and Black-legged Kittiwakes (Rissa tridactyla) were captured from their breeding colonies in lower Cook Inlet, Alaska, 2016-2023. Kittiwakes, murres, Glaucous-winged Gulls (Larus glaucescens) and Horned Puffins (Fratercula corniculata) were collected in Prince William Sound, Cook Inlet, and Unalaska.
