dc.description.abstract Pop-up satellite archival tags (PSATs) are now widely used to document the geographic and vertical movements of large pelagic fishes. These instruments record measurements of ambient light, depth and temperature at regular intervals and the light data are used to compute daily estimates of latitude and longitude. Several methods have been developed to improve those estimates, including the application of Kalman filter models and matching sea surface temperatures (SST) from tags with remotely sensed SSTs. Despite their widespread use, few studies have evaluated the accuracy of raw estimates of location from PSATs or quantified the improvements that may result from refinement techniques. To assess the accuracy of raw and refined estimates of locations from PSATs, we attached two PSATs and one Argos satellite-linked transmitter (SAT tag) to one whale shark (Rhincodon typus) at Ningaloo Reef, Western Australia. The root mean square error (RMSE) in raw estimates of location provided by the PSATs was 5.16 degrees latitude and 2.00 degrees longitude. Estimates were more accurate after processing the data with a Kalman filter (RMSE = 2.97 degrees latitude and 0.78 degrees longitude) and most accurate after processing with a Kalman filter model that integrates SST measurements (RMSE = 1.84 degrees latitude and 0.78 degrees longitude). We also assessed the precision of the PSAT-derived locations, and depth and temperature measurements by comparing the data from the two PSATs. Our findings support the use of archival tag data to reconstruct the large-scale movements of marine animals and demonstrate the significant improvements that may result from two refinement techniques.
