For this year’s exercise, the Coast Guard and University of Cambridge deployed a Gavia Scientific AUV equipped with side scan sonar and obstacle avoidance radar. This allowed the device to map underneath ice ridges and provide underwater imagery which will help researchers to better understand the topography of ice floes.

But perhaps the most noteworthy point of all, looking ahead, is the AUV. Buried in the Methods section of the paper is this, describing an incident part-way through the field campaign: “… the AUV lost track of the rugged ice-shelf basal topography, ascended into a crevasse, collided with the ice and executed avoidance manoeuvres that prompted it to abort its program and take a direct route to the recovery waypoint. After minor repairs, …”. Putting it another way, the world is now a little bit smaller, but not less dramatic, than it used to be.

Underneath the glacier, the explorer’s acoustic instruments found a huge ridge that rises about 1,300 feet up from the rest of the seabed upon which the glacier rests. But the relatively warm ocean water has been cutting away the glacier’s underside. According to co-author Pierre Dutrieux, that ridge can help explain why ice loss accelerated so recently.

The discovery of an underwater ridge in West Antarctica could help explain why there has been an acceleration in the ice flowing from a glacier in the area. Researchers suggest that the base of Pine Island Glacier once sat on the ridge, but recently became detached from the feature. The team made the discovery during surveys that used a unmanned submarine to examine waters under the glacier.
