CAGE, OAFS and Paleo-CIRCUS cruise to Northwest Norway, Jan Mayen and East Greenland aboard R/V Helmer Hanssen
Chief Scientist: Tine L. Rasmussen
Co-Chief Scientist: Kasia Kamelcyzk
Introduction
From the morning of June 23rd to the morning of July 7th 2013, the Department of Geology of the University of Tromsø, Norway, arranged a scientific cruise aimed at investigating the western Northern Norwegian margin and the central Nordic seas and east Greenland margin| on R/V “Helmer Hanssen”. Investigated areas were (in order of visiting sites on the cruise): the northwestern Norwegian Sea margin to north of Jan Mayen, and the western Greenland Sea north and off Scorebysund. The scientific sampling was done within the framework of ongoing projects at the Department of Geology, University of Tromsø: “CAGE (CoE): Arctic Gas Hydrate, Environment and Climate”, hereunder the projects “OAFS-Ocean Acidification Fram Strait” and “Paleo-CIRCUS”.
A total of 12 gravity cores, 5 piston cores and 9 multi-cores (with a total of 27 sub-coresretrieved), 15 plankton net casts and 20 CTD (conductivity-temperature-depth) casts were performed at the western Barents Sea slope, and the Barents Sea.
>44 chirp profiles and multibeam echo sounder lines were acquired during transits and during surveys of potential core sites.
