Tracking Data for Marbled Godwits (Limosa fedoa)

Science Center Objects

Available here are tracking data of Marbled Godwits, a large-bodied shorebird that, in Alaska, nests in the southwestern portion of the state. These data were collected to better understand the timing and patterns of migratory movements and seasonal use of different coastal areas in the Pacific region.

USGS Alaska Science Center scientists collect 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, and identify geographic areas repeatedly used by wildlife that may indicate sites of importance to species and populations. Tracking data from other wildlife species can be found at:

Data Packages

Marbled Godwit Telemetry Data

These data packages contain the data collected from satellite transmitters attached to free-ranging animals. The packages include both raw and processed location and sensor data. The raw data includes data as originally retrieved from the Argos System. The processed data have been filtered for location plausibility, and sensor data have been decoded into standard measurement units. For most users, the processed data will be preferred.
