Grain-size distributions, End-member modelling and Th-fluxes of South Atlantic surface sediments ...
We present the characteristics of the lithogenic components of seafloor surface sediments covering the entire South Atlantic Ocean (from the equator to Antarctica). These samples were collected by multiple seagoing expeditions between 1988 and 2005. By using end-member modelling on the multi-modal g...
