공공데이터포털

These morphometric data are in two tables from surfbirds (adults and chicks) captured at two locations in southcentral Alaska, 1997-1999.

Tracking Data for Surf Scoters (Melanitta perspicillata)

공공데이터포털

This data release includes 2 child items with tracking data for Surf Scoters, a seaduck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. Child Item 1: "Argos Satellite Tracking Data for Surf Scoters (Melanitta perspicillata) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Surf Scoters (Melanitta perspicillata) - Raw Data" -- All raw data collected from Argos satellite transmitters, provided for completeness of the archive. The quality-controlled, "Argos Processed Data" (Child Item 1) are better suited for most analytical purposes.

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.

Adult Shorebird Morphological Measurement Data

공공데이터포털

This dataset consists of three tables, 1) taxonomy, 2) contributors, and 3) shorebird morphological measurements collected from various species captured from 1977-2021. In addition, photographs of plumage patterns are available for several species. Researchers with the U.S. Geological Survey - Alaska Science Center, along with collaborators from many government agencies and research institutions, have studied shorebirds at numerous sites across North America, the Pacific Ocean, Australia, and New Zealand. This release includes over 10,000 observations relating to 35 shorebird species.

Marine Bird and Mammal Surveys in Gulf of Alaska Fjords, 2004-2011

공공데이터포털

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.

Aerial Surveys of Shorebirds at Pre-migratory Staging Sites in Western Alaska, 2018-2019

공공데이터포털

The data in this table document the numbers of four species of shorebird counted during aerial surveys of coastal sites in western Alaska. Survey regions encompassed coastline between the mouths of the Kuskokwim and Yukon rivers, and the northern coast of the Alaska Peninsula from the mouths of the Kvichak and Naknek rivers to Nelson Lagoon. Surveys were flown from 7-9 September 2018 and 20-22 August 2019. Also provided are two Keyhole Markup Language (KML) files with the start and end points of the aerial survey transect segments, and copies of the aerial survey images from which the counts were derived.
