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...

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)...
