This dataset consists of one table with annual counts from population plots of Black-legged Kittiwakes and Common Murres at two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska.

This dataset consists of one table with annual population counts (censuses) for Black-legged Kittiwakes and Common Murres at two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska.

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 Prince William Sound, Gulf of Alaska. The first table consists of information on seabird diet samples including the sampling method and number of prey types identified per sample ("seabirdDiets_foodSample_middletonIsland.csv"). The second table is similar to the first table, however, the samples have been subdivided by individual prey species ("seabirdDiets_samplePrey_middletonIsland.csv"). The third table consists of information specific to sampled prey items, such as prey taxa identification and morphometrics ("seabirdDiets_preyItems_middletonIsland.csv"). The fourth table consists of processed diet information and indices specific to Black-legged Kittiwake and Rhinoceros Auklet prey ("seabirdDiets_RHAU_BLKI_diets_middletonIsland.csv"). The fifth table contains prey species and seabird species taxonomy information ("seabirdDiets_speciesTaxonomy_middletonIsland.csv"). All samples included in the tables of this data release were collected during the spring and summer months from 1978-2022.

This data package includes 7 child items with data about the seabird abundance, productivity, predator disturbance, morphology of forage fish, and hydroacoustic characteristics at Lower Cook Inlet seabird colonies. Child Item 1: "Predation of Common Murre Eggs at Two Seabird Colonies in Lower Cook Inlet, Alaska". Child Item 2: "Forage Fish Morphology Data from Lower Cook Inlet, Alaska". Child Item 3: "Hydroacoustic Survey Data from Lower Cook Inlet, Alaska". Child Item 4: "Nesting Productivity of Black-Legged Kittiwakes and Common Murres at Two Seabird Colonies in Lower Cook Inlet, Alaska". Child Item 5: "Population Counts at Two Seabird Colonies in Lower Cook Inlet, Alaska". Child Item 6: "Population Plots at Two Seabird Colonies in Lower Cook Inlet, Alaska". Child Item 7: "Common Murre Disturbance Data on Gull Island, Kachemak Bay, Alaska".

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.

This data package contains two tables with habitat measurements from each sampling point used in avian point-transect surveys on the Seward Peninsula in 2012 and the locations of those sites. Measurements include percent cover and canopy height of alder (Alnus spp.), dwarf birch (Betula spp.), ericaceous shrubs (e.g., Empetrum, Vaccinium spp.), herbaceous, lichen (e.g., Cladonia spp.), and willow (Salix spp.).

These data describe marine bird and mammal surveys conducted in glacial fjords of coastal Alaska. Data were collected to document the at-sea distribution and abundance of marine birds and mammals in Glacier Bay National Park (2004), Prince William Sound (2010), Icy Bay (2011) and Yakutat Bay (2011). Following standard US Fish and Wildlife protocols for strip surveys.

This data package contains three tables: 1) avian point-transect survey data collected on the Seward Peninsula in 2012, 2) locations of all survey sites, and 3) an avian taxonomy table for reference.
