Robot Submarine Maps World's Deepest Sinkhole

holy_calamity writes "The world's deepest water-filled sinkhole has finally been mapped — by a robotic submarine whose descendants may one day swim on one of Jupiter's moons. The last attempt to find the bottom resulted in the SCUBA diving depth record and the death of a diving legend. The sub's sonar found that the divers had descended to only about 10m from the floor. The sub's mapping also indicated that the sinkhole, which is over 300m deep, could connect to even deeper caves."

Re:Why not for this one?

Its not the depth, its the fact that its a sinkhole. uncharted at that, you need a ROV that can work in an enclosed space and create a map to know where it is accurately and how to get back.
