230Th excess, U isotopes, elemental data together with microfossil data and their stable isotopes ...
This dataset comprises previously published and new data on the composition of sediment cores from the Arctic Ocean. New data are supplied for cores PS51/038-4, PS72/396-5 and PS72/396-3: For PS51/038-4 and PS72/396-5, we provide data on 230Th excess, 238U, 234U/238U together with bulk Ca, Mn and S...

| Summary: | This dataset comprises previously published and new data on the composition of sediment cores from the Arctic Ocean. New data are supplied for cores PS51/038-4, PS72/396-5 and PS72/396-3: For PS51/038-4 and PS72/396-5, we provide data on 230Th excess, 238U, 234U/238U together with bulk Ca, Mn and S concentrations. For PS72/396-3, we provide data on planktonic foraminifera, their oxygen and carbon isotopic composition, allochtonous forminifera fractions and the abundance of Cibicides lobatulus subsp. grossa. Thorium and uranium isotopes were measured on a sector-field ICP-MS (Element2) via isotope dilution; elemental concentrations on an ICP-OES iCAP; foraminfera abundances after freeze-drying and sieving of a mean sample size of 87 g; and stable isotopes on a Finnigan MAT 251 isotope ratio gas mass spectrometer directly coupled to a Kiel I automatic carbonate preparation device; all at the Alfred Wegener Institute. 230Thex was calculated by subtracting the activity of 234U from 230Th.Existing data comprise ... |
