Researchers at the Center of Ocean Technology programmed a torpedo-shaped glider to detect and map fish sounds along the West Florida Shelf. As the glider blends in with the ocean dwellers, it samples ocean sounds every five minutes.
"The glider also recorded location data and measured seawater temperature, salinity, and depth over the course of 1 week. By comparing the grunts and whistles on their recordings to known fish calls, University of South Florida researchers found red grouper (Epinephelus morio) and toadfishes (Opsanus spp.) were the most frequent fish sounds recorded, the team reports this month in Marine Ecology Progess Series."
By tracking our underwater neighbors, researchers hope to better understand species distribution and likely breeding areas, which will help guide conservation efforts.
