Despite the obvious power and advantages of the Argos system to track animals by satellite, the data generated are difficult for many biologists to exploit. A broad range of skills is required to efficiently download, collate, filter and interpret Argos data. Integration of animal movements with other physical (eg remote sensing imagery) and anthropogenic (eg fishery distributions) datasets presents additional technical and computing challenges. The Satellite Tracking and Analysis Tool (STAT) is a freely available system designed for biologists who work on animal tracking; it includes a set of standardized tools and techniques for data management, analysis, and integration with environmental data. STAT logs in to the Argos computer network each day and downloads all available locations and associated data for each user. These data are parsed and stored in a relational database and automatically backed up to an …
