Source apportionment results for <5 μm size fraction sediments of core PS75/056-1
This dataset contains the source apportionment results for the dust fraction (<5 µm size fraction) of sediment core PS75/056-1 from the South Pacific Subantarctic Zone (55.16°S, 114.78°W; 3581 m water depth) collected during R/V Polarstern expedition ANT-XXVI/2 (PS75 BIPOMAC) in 11/2009-01/2010 (...
