Lithogenic thorium fluxes into 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. This dataset describes the 230-Thorium-normalized...

Description
Summary: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. This dataset describes the 230-Thorium-normalized fluxes of 232-Thorium, and the calculated specific fluxes for the four end-members that were obtained for the grain-size distributions (as presented in doi:10.1594/PANGAEA.961711). In addition, we present dust fluxes from model simulations at the same stations as the direct observations.
