4. Satellite Telemetry

5. Biotelemetry Weddell Seal Work in the Antarctic

6. Telemetry Radiotelemetry: – transmitter size can be quite small (<1 g) – Transmission distance limited by geography – Relatively inexpensive ($150 per transmitter) – Can transmit location, movement, some physiological data Satellite Telemetry (GPS): – Larger transmitters (>30 g) – No limitation on transmission distance – Extraordinarily expensive ($10,000 per trans) – Can transmit location, movement, or physiological data Biotelemetry – Can record heart rate, depth, movement, speed – Usually the unit on the animal must be retrieved to download the data
