This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 92 satellite transmitters attached to adult Yellow-billed Loons on their breeding range in Arctic Alaska and Canada, 2002-2017. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) contain the raw Argos DIAG (Diagnostic) data, one in the legacy verbose ASCII format and one in a tabular Comma Separate Value (CSV) format. Two other data files (with identical content) contain the raw Argos DS (Dispose) data, one in the legacy verbose ASCII format and one in a tabular CSV format. The fifth file, "deploymentAttributes", contains one record for each transmitter deployment in a CSV formatted table. The deployment attributes file contains information such as when the transmitter was attached to the animal, when tracking of a live animal ended, and a variety of variables describing the animal and transmitter. This table is identical to the "deploymentAttributes" table in the "processedData" folder of this data package.

This metadata document describes the data contained in the "processedData" folder of this data package. This data package contains all data collected by the Argos System from 92 satellite transmitters attached to adult Yellow-billed Loons on their breeding range in Arctic Alaska and Canada, 2002-2017. The raw data were processed to accomplish two goals: flag implausible location estimates and decode raw sensor data. Three Comma Separate Value (CSV) tables are included in the "processedData" folder of this data package: 1) the "diag_filteredLocations" table contains one record for every location estimate collected, accompanied by a binary flag that denotes an algorithm's plausibility check. Each record also includes a 'Tracking_Status' variable that denotes whether the location was collected from a live animal, a dead animal, or shed transmitter, 2) the "decodedSensor" table contains decoded sensor data such as a transmitter's temperature, battery voltage, and motion (activity), and 3) the "deploymentAttributes" table contains one record for each transmitter deployment in a CSV formatted table. The deployment attributes file contains information such as when the transmitter was attached to the animal, when tracking of a live animal ended, and a variety of variables describing the animal and transmitter. This table is identical to the "deploymentAttributes" table in the "rawData" folder of this data package.

This data release includes 1 child item with tracking data for Pacific Loons, a species that breeds throughout much of Alaska and winters throughout the Pacific Ocean basin, along the coasts of East Asia and North America. Child Item 1: "Argos Satellite Tracking Data for Pacific Loons (Gavia pacifica) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters.

This data release includes 2 child items with tracking data for Red-throated Loons, a species that breeds in coastal areas throughout Alaska and winters along the Pacific coasts of North America and Eurasia. Child Item 1: "Argos Satellite Tracking Data for Red-throated Loons (Gavia stellata) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Red-throated Loons (Gavia stellata) - 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.

This data release includes 2 child items with tracking data for Whimbrels, a shorebird found throughout tundra and boreal habitats of Alaska during the summer and winters along the coasts of the continental U.S., and central and South America. Child Item 1: "Argos Satellite Tracking Data for Whimbrels (Numenius phaeopus) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Whimbrels (Numenius phaeopus) - 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.

Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research studies and management decisions. Since the mid-1980s, the USGS Alaska Science Center has collected data from wildlife tracking devices to: determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on various behaviors, determine timing of life cycle events, and identify geographic areas repeatedly used by wildlife that may be of significance to other species and populations. These datasets are a collection of the USGS Alaska Science Center wildlife tracking data arranged by species or closely allied species groups. Details of tracking projects, devices, methods, and data can be found within each species directory.

This data package contains location data collected by the Argos System (CLS America, Inc.) from satellite transmitters attached to 116 Lesser Yellowlegs captured at multiple sites across their breeding and nonbreeding range in North America, 2018-2021. The raw data were processed to accomplish two goals: 1) flag implausible location and 2) remove locations within Joint Base Elmendorf-Richardson (JBER) and Eielson Air Force Base boundaries. Removal of locations in military land boundaries is required due to federal guidelines by Department of Defense (DoD) Public Affairs office and DoD Partners in Flight. Due to data sharing constraints of participating agencies, not all the locations (i.e., latitude and longitude) have been released. Two Comma Separate Value (CSV) tables are included in this data package: 1) the "lesserYellowlegs_USFWS_argosGPS_deploymentAttributes.csv" table contains one record for each transmitter deployment and 2) the "lesserYellowlegs_USFWS_argosGPS_processedData.csv" table contains one record for every Argos location estimate collected.

This data release includes 1 child item with tracking data for Black Brant, a goose species that breeds in coastal areas of Alaska, northwestern Canada, and northeastern Russia and winters along coastal areas of North America from western Alaska to Mexico. Child Item 1: "Light-Level Geolocator Tracking Data for Black Brant (Branta bernicla nigricans)" -- Tracking data collected from light-level geolocator attached Black Brant at breeding areas in Alaska, 2011-2014.

This data release includes 2 child items with tracking data for Spectacled Eiders, a seaduck species that breeds only in Alaska and Russia and spends the winter exclusively in the Bering Sea. The Alaska breeding population is listed as threatened under provisions of the Endangered Species Act. Child Item 1: "Argos Satellite Tracking Data for Spectacled Eiders (Somateria fischeri) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Spectacled Eiders (Somateria fischeri) - 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.

This data release includes 2 child items with tracking data for Bar-tailed Godwits. One of the subspecies, Limosa lapponica baueri, nests in Alaska and spends the nonbreeding season in New Zealand and eastern Australia whereas L.l.menzbieri nests in Siberia and spends the nonbreeding season in western Australia. Child Item 1: "Argos Satellite Tracking Data for Bar-tailed Godwits (Limosa lapponica) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Bar-tailed Godwits (Limosa lapponica) - 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.
