In the middle of the 2010s, Erebus 2014 and Terror 2016 were found off King Williams Island in Canada, and now researchers with robots have entered one of the ships, HMS Terror. Thanks to a layer of sludge, the icy water and the lack of natural light, the wreck is in unexpected good condition - even though it has been underwater for a century and a half.
