This data release includes 2 child items with tracking data for three large-bodied gull species and hybrids (Larus species) utilizing coastal areas of Alaska. Child Item 1: "Argos and GPS Satellite Tracking Data for Three Large-Bodied Gull Species and Hybrids (Larus spp.) - Processed Data" Quality-controlled data collected from Argos and Argos-linked GPS satellite transmitters. Child Item 2: "Argos and GPS Satellite Tracking Data for Three Large-Bodied Gull Species and Hybrids (Larus spp.) - Raw Data" All raw data collected from Argos and Argos-linked GPS satellite transmitters, provided for completeness of the archive. The "Processed Data" (Child Item 1) are better suited for most analytical purposes. Version...

Child Item 1: Argos and GPS Satellite Tracking Data for Three Large-Bodied Gull Species and Hybrids (Larus spp.) - Processed Data

This metadata document describes the data contained in the "Argos GPS Processed Data" (Child Item 1) of this data release. This data release contains all data collected by the Argos System from 6 satellite transmitters attached to Glaucous-winged gulls on Middleton Island and 42 Argos-linked GPS satellite transmitters attached to three species of large-bodied gulls (genus Larus) and hybrids thereof, captured at landfills in southcentral, western and northern Alaska. The transmitters carried GPS receivers, so GPS tracking data represent the backbone of this data release. However, because the GPS locations were communicated through the Argos System, a time series of Argos (Doppler) tracking data also exists and is...

Tracking Data for Black Brant (Branta bernicla nigricans)

This data package contains all location data collected by light-level geolocators attached to 68 Black Brant at breeding areas in Alaska. The data include: a deployment attributes file with details of each brant at the time of capture, the raw light-level data in ASCII files as downloaded and decompressed, and twice-daily estimated locations.

Nesting Period Data for Black Brant (Branta bernicla nigricans) in Alaska

This data package contains one table with nest initiation and end dates and clutch sizes from Black Brant (Branta bernicla nigricans) at two breeding colonies in Alaska. Data include nesting period determined by either nest visits or light-level data recorded by geolocators attached tarsal bands.
