This dataset contains fatty acid data expressed as mass percent of total fatty acids for several species potentially preyed upon by yellow-billed loons. These data were utilized in a quantitative fatty acid signature analysis to estimate the diet of yellow-billed loons nesting on the Arctic Coastal Plain of Alaska (Haynes et al. 2015).

This dataset contains fatty acid data expressed as mass percent of total fatty acids from Chukchi Sea polar bears.

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.

These data are in four tables relating to complete blood count (CBC), biochemistry, blood gas analysis, corticosterone, serum protein electrophoresis, and sample attribute data of adult Pacific (Gavia pacifica) and Red-throated Loons (G. stellata) breeding in northern Alaska in 2023.

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and contain diet data from Black-legged Kittiwakes (BLKI), Rhinoceros Auklets (RHAU), and Tufted Puffins (TUPU) located on Middleton Island in the Gulf of Alaska. This data release consists of seabird diet sample data and prey identification and morphometrics.

This data set contains food habits determined from stomachs of northern fur seals collected from pelagic waters during 1981-1985. Prey items were identified using hard parts including bones, otoliths, and cephalopod beaks.

This data release contains a mark-resight encounter history table for Pacific and Yellow-billed loons from the Arctic Coastal Plain in northern Alaska, 2011-2014.

This data set contains Steller sea lion diet data based on analysis of scats collected during summer (May-September) and winter (November-April) rookeries and haulouts in Alaska during 1990 to 2009. Prey items from 87 prey taxa were identified using hard parts including bones, otoliths, and cephalopod beaks. Frequency of occurrence was calculated for 375 site-year-season combinations, and used in the analysis published by Sinclair et al. (2013). This dataset includes the thirteen primary prey taxa (frequency of occurrence >= 5%) identified in the Sinclair et al. (2013) study.
