Grain-size records from South Pacific (PS75/056-1) and South Atlantic (ODP Site 177-1090) ...

This dataset describes dust particle size of two marine sediment records in the Southern Ocean. The first record is South-Pacific core PS75/056-1 (55.16°S, 114.78°W; at 3581m water depth), recovered during R/V Polarstern expedition ANT-XXVI/2, PS75 (Gersonde, 2011). Samples from 0.07-9.93 m core dep...

Description
Summary:This dataset describes dust particle size of two marine sediment records in the Southern Ocean. The first record is South-Pacific core PS75/056-1 (55.16°S, 114.78°W; at 3581m water depth), recovered during R/V Polarstern expedition ANT-XXVI/2, PS75 (Gersonde, 2011). Samples from 0.07-9.93 m core depth were analysed (N=183), and grain sizes were analysed with the laser particle sizer Beckmann Coulter LS13 320 at NIOZ, The Netherlands. This record spans the last ~260 kyr. The second sediment record is ODP Site 1090 (42.91°S, 8.90°E, at 3702m water depth), recovered during the Ocean Drilling Program Leg 177 expedition (Gersonde et al., 1999). Samples from 0.00-4.84 m were analysed (N=333), and grain sizes for ODP Site 1090 were analysed with the laser particle sizer Malvern Mastersizer 2000 at ETH Zurich, Switzerland. This record spans the last ~160 kyr. For both records, grain-size analyses were performed on the isolated terrigenous fraction, after the biogenic components (organics, carbonates and biogenic ...
