RSSTurning fish into audio pingers...
Turning fish into high-tech acoustic pingers, it's a like a real version of Electroplankton - "The scientists have designed a field study that uses acoustic telemetry technology to track continuously the movements and habitat use of red and black grouper in the Dry Tortugas National Park, the 46-square-nautical-mile marine reserve. The groupers will be fitted with transmitters or "pingers" that emit unique acoustic codes underwater approximately every 20 seconds...The scientists are arranging the hydrophone receivers in a grid array, so they can systematically obtain continuous, precise tracks of animal locations, including daily travels and frequently visited areas."
