From the morning of May 26th to the morning of June 1st 2013, the Department of Geology of the University of Tromsø, Norway, arranged a scientific cruise aimed at investigating the western Barents Sea margin and the western Barents Sea on R/V “Helmer Hanssen”. Investigated areas were (in order of visiting sites on the cruise): the western Barents Sea slope to northwest of Bjørnøya, and the western Barents and north Norway. The scientific sampling was done within the framework of the ongoing project at the Department of Geology, University of Tromsø: “OAFS-Ocean Acidification Fram Strait”.
A total of 3 gravity cores, 1 box-core, 5 multi-cores (with a total of 15 sub-cores retrieved), 13 plankton net casts and 13 CTD (conductivity-temperature-depth) casts were performed at the western Barents Sea slope, and the Barents Sea.
>17 chirp profiles and multibeam echo sounder lines were acquired during transits and during surveys of potential core sites.
