The freezing waters underneath Antarctic ice shelves and the underside of the ice itself are of great interest to scientists… but who wants to go down there? Leave it to the robots. They won’t complain! And indeed, a pair of autonomous subs have been nosing around the ice for a full year now, producing data unlike any other expedition ever has.
The mission began way back in 2017, with a grant from the late Paul Allen. With climate change affecting sea ice around the world, precise measurements and study of these frozen climes is more important than ever. And fortunately, robotic exploration technology had reached a point where long-term missions under and around ice shelves were possible.
The project would use a proven autonomous seagoing vehicle called the Seaglider, which has been around for some time but had been redesigned to perform long-term operations in these dark, sealed-over environments. ne of the craft’s co-creators, UW’s Chris Lee, said of the mission at the time: “This is a high-risk, proof-of-concept test of using robotic technology in a very risky marine environment.”
The risks seem to have paid off, as an update on the project shows. The modified craft have traveled hundreds of …read more
