The short film TAGGED-YOU'RE IT! takes viewers beneath the surface of Gray's Reef National Marine Sanctuary, and reveals how researchers are using technology to learn more about the habits of the fish species that spend time in the sanctuary. Click here to view the video

On June 11, 2010, NOAA divers returned to Gray's Reef to visit a site where ten tagged fish had been released during the 2010 Gray's Reef R/V NOAA Ship Nancy Foster research cruise the month before. The purpose of the trip was to attempt to locate the tagged fish using a VEMCO Diver Swim Board (DSB) that can detect their acoustic transmitters. Each fish had been surgically implanted with an acoustic tag that emits a unique signal that the DSB can identify. During the dive, the DSB detected seven of the ten fish, and divers observed several of them (identified by the yellow "spaghetti" tag that is attached near their dorsal fin). The videos below depict several tagged fish, as well as divers using the DSB to track their movement.
