Read our privacy policy Hoping to collect data on the Southern Ocean’s Ross Sea, scientists deployed Marlin, an autonomous underwater vehicle, two years ago. Marlin helped the University of East Anglia researchers to reveal the impact of warming ocean waters on a major Antarctic ice shelf. The glider was supposed to travel northward into the open water - but Marlin became caught in a southward-moving current and got stuck underneath the Ross Ice Shelf.
