| Abstract | RV Tangaroa voyage FOCUS-AUV (TAN2011) took place over 29 days with the primary objective of deploying the University of Gothenburg HUGIN 3000 AUV. Due to the COVID-19 pandemic travel restrictions none of the international scientists named in the Eurofleets+ proposal were able to participate in this voyage. A revised programme and science team was developed to account ensure a successful campaign. A total of 14 dives were completed out of 17 planned dives. The survey areas had to be modified to allow for weather conditions, however the final overall operations and survey coverage are considered highly successful. Instrument issues meant that not all dives include the full data suite but the main instrument, the EM2040 multibeam echosounder, operated well on all surveys. In between AUV dives operations included multicoring, gravity coring, video tows, acoustic surveys, and lander and mooring deployments. A significant amount of media outreach meant that the science of the voyage was widely publicized and achieved very good coverage. There are exceptional opportunities in this new dataset to gain scientific insights into the processes of canyon formation, the sedimentary processes associated with canyon flushing, and how submarine landslides and canyons interact. |
