Their earlier paper from 2021 discusses some of the earlier mapping the submersible did of the Doomsday glacier: https://www.science.org/doi/10.1126/sciadv.abd7254 https://www.science.org/doi/10.1126/sciadv.abd7254
I was surprised by how complicated the topography is with these underwater currents. They cut upside down canyons and create some complicated caverns, overhangs, etc. just like rivers do overland.
- moffkalast 2y agoThat is genuinely surprising, one would imagine it being mostly flat. Also oof, they lost a Kongsberg MBES, those things are beyond expensive ($100k+). Probably dwarfs the cost of the rest of the AUV. Then again it's also a Kongsberg AUV so perhaps not... https://www.kongsberg.com/discovery/autonomous-and-uncrewed-solutions/auv/hugin https://www.kongsberg.com/discovery/autonomous-and-uncrewed-...
