WHOI technicians Chris Basque (left) and Jim Ryder (center) wait with the Armstrong Bos’n (right) to get a position message from the GPS beacon (white cylinder). The OOI moorings are outfitted with several of these tracking beacons that report GPS positions back to shore via satellite. Prior to deployment, the beacons are turned on and tested.
