Current Projects - Fish Tracking


In May 2010, we affixed a hydrophone to our glider to listen to acoustic tags in Auke Bay near Juneau Alaska. This pilot project was designed to determine if gliders might be used to track tagged fish. We deployed a mooring buoy affixed with a number of tags and hydrophones spaced vertically in the water column. The gliders acted as both fish and as hydrophone carriers while they swam by the mooring at various depths and distances. The data collected from this experiment has helped us determine the sensitivity of the tags to ocean stratification and separation distance to the hydrophone. This project was funded by the National Undersea Research Program and was kindly supported by the NOAA Marine Fisheries Lab at Auke Bay. Hydrophone
