Autonomous Submarines Spend a Year in Antarctic Ice – TechCrunch



The frozen waters beneath the Antarctic glaciers and the lower side of the ice are of great interest to scientists … but who wants to go there? Leave it to the robots. They will not complain! Indeed, two autonomous submarines have been moving around the ice for a year, producing data unlike any other expedition she has ever had. With climate change affecting sea ice around the world, accurate measurements and studies of these frozen climates are more important than ever. Fortunately, robotic research technology has reached a point where long-term missions are possible under and around ice shelves.

The project will use a proven autonomous seagoing ship called Seaglider that has existed for some time but has been revised to carry out long-term operations in these dark, enclosed environments. None of the craft co-workers, Chris Li of UW, said about the mission at the time: "This is a high-risk test, proof of the concept of using robotic technology in a very risky marine environment."

paid, as the project update shows. Modified vessels have traveled hundreds of miles in one year of autonomous operation.

It is not easy to stay long on the coast of Antarctica for many reasons. But leaving the robots to work while resting somewhere else for a month or two, that is definitely feasible. in a UW message today. "Planners are able to orient themselves as they wish to explore the interior of the cavity … This is the first time that any of the modern platforms with long-lasting stability has made permanent measurements under the ice shelf."

You can see the paths of the robotic platforms below as they scout around the edge of the ice and then dive on journeys of increasing length and complexity:

Both are equipped with ice-cooling sensors above, water temperature and other interesting data points. the longest and potentially most fruitful. Seagliders are smaller, lighter and better equipped for long-term missions. One trip lasted 87 miles!

The mission continues, and two of the three original Seagliders are still working and ready to continue their work.
