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 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 included. Four Comma Separate Value (CSV) tables are included in the "processedData" folder of this data package: 1) the "GPS_filteredLocations" table contains one record for every GPS location obtained, accompanied by a binary flag that denotes an algorithm's plausibility check (based on a speed threshold of 35 m/s); ...
