[{"name":"oden-swerus-2014-expedition-1","title":"Data from expedition SWERUS-C3, Arctic Ocean, 2014","summary":"The SWERUS-C3 (Swedish \u2013 Russian \u2013 US Arctic Ocean Investigation of Climate-Cryosphere-Carbon Interactions) expedition was carried out during the summer of 2014 in the Arctic Ocean with the Swedish icebreaker Oden serving as the research platform.\r\nThe expedition consisted of two 45-day legs. Leg 1 started on July 5 from Troms\u00f8, Norway, and worked along the Siberian continental shelf towards Barrow, Alaska, where both scientific personnel and crew were replaced. Leg 2 departed from Barrow on August 21, and took Oden farther out from the Siberian continental shelf and slope into the deep central Arctic Ocean. Leg 2 ended on October 5 in Troms\u00f8, Norway.\r\n\r\nSWERUS-C3 was a multi-disciplinary program aiming to investigate the linkages between climate, the cryosphere (sea ice and coastal permafrost) and carbon release from the sediment, leading to addition of greenhouse gases to the atmosphere.\r\n\r\nData provided in the database here comprise biogeochemistry (biomarkers and organic carbon), marine geophysics (bathymetry\/seafloor topography and marine sediment properties), oceanography (physical and chemical properties of ocean water), and meteorology (weather station, micrometeorology, trace gas measurements).\r\n","citations":"\n  The SWERUS Scientific Party, 2016, Cruise report SWERUS-C3 Leg 1, Meddelanden fr\u00e5n Stockholms universitets Bolin Centre for Climate Research No 1, Stockholm, 200 pp.\n\n  The SWERUS Scientific Party, 2016, Cruise report SWERUS-C3 Leg 2, Meddelanden fr\u00e5n Stockholms universitets Bolin Centre for Climate Research No 2, Stockholm, 190 pp.\n\n  Martens, J., Wild, B., Pearce, C., Tesi, T., Andersson, A., Br\u00f6der, L., O'Regan, M., Jakobsson, M., Sk\u00f6ld, M., Gemery, L., Cronin, T.
