HROV images of the Karasik Seamount seafloor collected during POLARSTERN cruise PS101
On the 30th September 2016 the Hybrid-Remote Operated Vehicle (HROV) 'Nereius Under Ice' (NUI) was used to conduct a ~12 hr dive to image in high resolution a 500 m x 500 m area of the Karasik seamount with a pair of cameras. These cameras were a bespoke system consisting of a down-looking...
