A Season at the Sørsdal: Operating an Autonomous Underwater Vehicle beneath an Antarctic ice shelf
The University of Tasmania’s world-leading polar Autonomous Underwater Vehicle (AUV) and its support crew have returned home after a successful first deployment in Antarctica.
The $5 million AUV, named nupiri muka, is the first untethered Australian AUV to dive under an ice shelf and joins those from the UK and Sweden as the only AUVs in the world with this capability.
Funded by the Australian Research Council (ARC) through the Antarctic Gateway Partnership, nupiri muka was successfully deployed under the Sørsdal Glacier ice shelf during the summer Antarctic season with support from the Australian Antarctic Program.
Peter King, from the University’s Australian Maritime College, led a support team of engineers and scientists who have opened the way for more ambitious polar research projects under ice shelves and sea ice in the future.
nupiri muka allowed them to study variables such as water temperature, salinity and current as well as the profile of both the seabed and the underside of the ice, while at the same time collecting sonar imagery and potentially data on the internal structure of the ice.
These large amounts of data will shed new light on the way in which Antarctic ice shelves melt.
This forum provides you with an opportunity to hear about this important expedition and view video from beneath the ice shelf.
