Brief description

This dataset consists of location points obtained from GPS data loggers and Satellite Platform Transmitter Terminals (PTT) attached to dugongs to determine large and fine scale movement patterns within the Shark Bay World Heritage Property (SBWHP). The length of deployment for each animal ranges from 10 days to 11 months with all locations falling within the boundaries of the SBWHP.
