This cruise follows Field Activity 2018-691-DD; however Amy Gartman will attend field work this year and collect samples, as opposed to 2018-691-DD, which had no USGS attendees and just donated samples. However location and sampling plan are the same.
Designed for operation from both RVs G.O. Sars and Kronprins Haakon (using the latter’s moon-pool when operating in ice-covered water).
RV “G.O. Sars” was delivered in 2003 and is owned by the Institute of Marine Research (75%) and the University of Bergen (25%). The main operating areas are the Barents Sea, the Norwegian Sea and the North Sea. The vessel has also carried out trips to the Mid Atlantic ridge and to the Antarctic. “G.O. Sars” is equipped for all types of marine research and can handle ROV Ægir 6000, AUV Hugin and Calypso giant piston corer.
