AUV “Ran” Missing

[GordMay]

The unmanned autonomous underwater vehicle [AUV], “Ran”, has gone missing, under the Thwaites glacier, in Antarctica.
The vehicle, owned by the University of Gothenburg, is one of three similar, in the world, that is used for research, and has contributed to important knowledge, about the so-called ‘Doomsday Glacier’.
During January of this year, Ran completed several successful dives under Thwaites, but during the last planned dive of the expedition, something went wrong.
After a long journey under the ice, the AUV did not appear at the programmed rendezvous point.
RV/IB "Araon" aborted the homeward journey and searches were conducted with acoustic search equipment, helicopters, and drones, without success. In the end, it was just a matter of realizing that Ran had been lost.
