Aquatic Animal Tracking with AUVs


The University of Delaware doctoral student, Danielle Haulsee, uses a Slocum glider to monitor acoustically-tagged sand tiger sharks along the U.S. east coast. The study represents the first measure of habitat selection by a marine animal using an AUV.

Autonomous Underwater Vehicles (AUVs), or gliders, are increasingly being used for marine and freshwater observations. OTN operates a fleet of four Slocum Gliders and one Wave Glider. Both types of gliders profile their environment and collect data from acoustically tagged animals that swim within range. OTN Slocum gliders have detected acoustically-tagged Atlantic bluefin tuna, blue shark, Atlantic salmon, and American eel.

The National Research Council of Canada (Canadian Science Publishing) now produces a journal covering the developments in the rapidly emerging international field of AUVs and their sensors.

The UDelaware work is supported by US IOOS, MARACOOS and NOAA Fisheries’ Proactive Conservation Program Award.
