Data from expedition SWERUS-C3, Arctic Ocean, 2014

Örjan Gustafsson, Martin Jakobsson, Andrey Koshurnikov, Igor Semiletov

The SWERUS-C3 (Swedish – Russian – 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.

The expedition consisted of two 45-day legs. Leg 1 started on July 5 from Tromsø, 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 Tromsø, Norway.

SWERUS-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.

Data 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).

Comments

The expedition formed the key component of the SWERUS-C3 research program with core funding from the Knut and Alice Wallenberg Foundation (KAW). The logistics of the expedition was financed by KAW and the Swedish Polar Research Secretariat.

The project was developed into a multi-disciplinary international research program investigating the contemporary and historical functioning of the climate-cryosphere-carbon (C3) system of the East Siberian Arctic Ocean and adjacent deep waters off the continental shelf.

SWERUS-C3 included principal investigators from Stockholm University, University of Gothenburg, Pacific Oceanological Institute, P.P. Shirshov Institute of Oceanology, Russian Academy of Sciences (RAS), National Tomsk Research Polytechnic University, International Arctic Research Center (IARC) at University of Alaska, Center for Coastal and Ocean Mapping at University of New Hampshire and Rice University.

Expedition participants were from Sweden, Russia, USA, Norway, Canada, UK, Germany, Belgium and the Netherlands.
