(2019) The dataset is included in one xlsx file with 12 data sheets.</p> <p> The core data includes:<br /> 1. Relative foraminifera abundance counts in the >125 μm size fraction, and the occurrence of <i>Turborotalita quinqueloba</i> in the 63-125 μm. Relative abundance is defined as: Abundant (≥50% of sample), Common (>100 specimens), Few (50-100 specimens), Rare (< 50 specimens), Barren (0 specimens). Intervals where <i>T. quinqueloba</i> occurs are marked by an 'X'.</p> <p> 2. Grain size measurements acquired at a 1-2 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 fine, medium and coarse silt volumes.</p> <p> 3. Physical properties measured using a GeoTek Multi-Sensor Core Logger: Bulk Density (g/cc) and Bartington loop sensor Magnetic Susceptibility (SI × 10⁻⁵).</p> <p> 4. ITRAX XRF scanner data at a 2 mm downcore resolution.</p> <p> Spreadsheet tabs:<br /> LOMROG12_PC07_Foraminifera; AO16_5PC_Foraminifera; LOMORG12-6PC_Grainsize; LOMORG12-7PC_Grainsize; LOMORG12-12PC_Grainsize; MSCL Data; LOMROG12-3PC_ITRAX_XRF; LOMROG12-6PC_ITRAX_XRF; LOMROG12-7PC_ITRAX_XRF; LOMROG12-12PC_ITRAX_XRF; AO16-12PC_ITRAX_XRF; AO16-5PC_ITRAX_XRF The six sediment cores are:<br /> LOMROG12-3PC, 1607 m water depth, 87.7247°N, -54.4253°E;<br /> LOMROG12-6PC, 2923 m water depth, 88.2511°N, -46.3972°E;<br /> LOMROG12-7PC, 2953 m water depth, 88.1976°N, -55.6845°E;<br /> LOMROG12-12PC, 1366 m water depth, 88.1085°N, 134.6451°E;<br /> AO16-5PC, 1253 m water depth, 89.0780°N, -130.5470°E;<br /> AO16-12PC, 1269 m water depth, 87.8577°N, 136.9875°E
