HYDROPHONE RETRIEVAL

Expedition Aboard DISCOVERY Yacht Fugitive
March 2016

SeaKeepers and the University of Miami Shark Research Center teamed up to retrieve and redeploy hydrophone receivers from Tiger Beach, Bahamas, onboard D/Y Fugitive and its tender, Vigilante. The hydrophones are secured underwater to pick up acoustic signals from tagged sharks swimming in proximity. About once a year, these hydrophones are picked up, cleaned, data downloaded, and then reinstalled. The data retrieved from the hydrophones provide information about shark behavior and migration, which in turn can be used towards protecting these threatened species.
