| Summary: | Piston core HH15-1252PC was collected in Vestnesa Ridge in the Western Svalbard margin. The core was logged with a GEOTEK Multi Sensor Core Logger and color imaged with a Jai L-107CC 3 CCD RGB line scan camera installed on an Avaatech XRF. One cm thick slices at 1 to 5 cm intervals. Samples were weighed, freeze-dried, and weighed again. They were subsequently wet-sieved over mesh-sizes 63 μm, 100 μm and 500 μm. The residues were dried at 40°C and weighed and weight percent of each grain size was calculated. Oxygen and carbon isotopes were measured on up to 20 pristine benthic (Cassidulina neoteretis and/or Melonis barleeanus; 150 to 250 μm size fraction) and planktic foraminifera (Neogloboquadrina pachyderma 100 to 500 μm size fraction). For trace element analyses, 10 to 30 pristine C. neoteretis (150 to 250 μm size fraction) or M. baleeanus (150 to 350 μm size fraction) were picked, crashed between two glass slides and cleaned following the oxidative-reductive approach (Boyle and Keigwin, 1985/1986; Pena et ... |
