(2019) The dataset includes: 1. Age model of core SWERUS-L2-31PC on the Greenland Ice Core Chronology 2005 (GICC05) timescale. 2. Physical properties measured at 1 cm intervals with a GeoTek Multi-Sensor Core Logger: Porosity (%), Bulk Density (g/cm³) and Magnetic Susceptibility (MS1, SI × 10⁻⁵) 3. Organic carbon content (Corg, % wt) of the sediment. The dataset is included in one spreadsheet (xlsx) file with three data tables. The same data are also included in three comma-separated values (csv) files. File content: ###### Age model * Depth (m) * Weighted mean age (GICC05 years b2k) * Median age (GICC05 years b2k) * Upper 99% credible interval (GICC05 years b2k) * Lower 99% credible interval (GICC05 years b2k) ###### Physical properties * Core * Section * Interval (cm) * Depth (m) * Weighted mean age (GICC05 years b2k) * Porosity (% vol) * Bulk Density (g/cm³) * MS1 (SI × 10⁻⁵) ###### Organic carbon * Depth (m) * Weighted mean age (GICC05 years b2k) * Corg (%) Code for missing values: NA The core was collected from 79.91° N, 143.23° E in 1120 m water depth. The age model is on the GICC05 timescale ([Rasmussen et al. 2006]( A new Greenland ice core chronology for the last glacial termination. J. Geophys. Res., 111, D06102). Note that credibility intervals do not include maximum counting uncertainty associated with the ice-core chronology, but only consider the uncertainty associated with the alignment between the 31-PC porosity data and GISP2 δ¹⁸O data.
