Alaska scientists send out underwater drone to follow fish

摘要

Tracking fish across Alaska's vast continental shelves can present a challenge to any scientist studying Alaska's seas. So, researchers at the University of Alaska Fairbanks have successfully tested a possible solution in the form of underwater gliders. Recently, Peter Winsor, associate professor of physical oceanography, and Andrew Seitz, assistant professor of fisheries, tested the use of autonomous underwater vehicles, called gliders, for tracking tagged fish. Winsor and Seitz suspended acoustic tags, usually implanted in fish, at different depths along a buoy line near Juneau. They then deployed two gliders fitted with an acoustic listening device to "hear" the signals from the tags.
