The reliability of VHF telemetry data for measuring attendance patterns of marine predators: a comparison with Time Depth Recorder data
Abstract: VHF radiotelemetry data has been used for over thirty years to monitor the behavior ... patterns of otariid seals. These data have been used in a wide variety of ways, from characterizing the ... attendance patterns. Yet the accuracy of VHF data has never been appropriately evaluated. Our study compares ... -collected Time-and-Depth Recorder (TDR) data used as the ‘true’ measurement of time spent onshore. Within ...
