Glider at Sea (image) Woods Hole Oceanographic Institution Caption Chief scientist Mark Baumgartner, Woods Hole Oceanographic Institution, secures a glider (with its wings removed) after it was recovered Dec. 4 from its three-week mission. The gliders are equipped with an underwater microphone and an iridium satellite antenna. The vehicle surfaces every few hours to get a GPS position and transmit data to shore-side computers.
