Marine sediment core data from De Long Trough, Siberian margin and slope, Arctic Ocean
Matt O'Regan
Sediment core data from four sites in the East Siberian Sea, Arctic Ocean. The cores were collected during the SWERUS-C3 expedition with icebreaker Oden 2014. The core data includes: 1. Physical properties measured at 1 cm intervals with a GeoTek Multi-Sensor Core Logger: PWave Velocity (m/s), Bulk Density (g/cc), Bartington loop sensor Magnetic Susceptibility (SI × 10⁻⁵). 2. Shear strength (kPa) measured at about a 30 cm interval using a fall cone device. 3. Ca/Ti ratios derived from an ITRAX XRF-scanner at a 2 mm downcore resolution. 4. Grain size measurements acquired at a 5 cm downcore resolution using a Malvern Mastersizer 3000 laser diffraction particle analyser. Data is averaged from 5 replicate measurements at each sample position. Data includes, % volume of sand, silt and clay, as well as the mean grain size and sorting.

Project
Swedish – Russian – US Arctic Ocean Investigation of Climate-Cryosphere-Carbon Interactions – The SWERUS-C3 Program – SWERUS-C3 is a multi-disciplinary program with base funding supported from by the Swedish Knut and Alice Wallenberg Foundation (KAW) aiming to investigate the linkages between Climate, Cryosphere (here: sea ice and coastal permafrost) and Carbon release from the sediment, with addition of greenhouse gases (GHG) to the atmosphere. SWERUS-C3 includes 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, the International Arctic Research Center (IARC) at University of Alaska, Center for Coastal and Ocean Mapping at University of New Hampshire and Rice University.
