[{"name":"oden-swerus-2014-sediment-de-long-1","title":"Marine sediment core data from De Long Trough, Siberian margin and slope, Arctic Ocean","summary":"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 \u00d7 10\u207b\u2075). 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.","citations":"O'Regan, M., Backman, J., Barrientos, N., Cronin, T. M., Gemery, L., Kirchner, N., Mayer, L.
