Traditionally, we calculate these fluxes using a combination of linear sedimentation rates derived from age models and sediment density, known as age model-derived bulk mass accumulation rates (BMAR). However, BMAR and the resulting paleoceanographic interpretations may suffer from substantial errors if lateral redistribution of sediments is not considered. In fact, this is expected to be a common phenomenon in the Southern Ocean due to the strong bottom water circulation induced by the Antarctic Circumpolar Current. In the study associated to this dataset, we assess export production and its drivers over the past ~1.4 Myr near the Drake Passage entrance using BMAR of biogenic Barium, organic carbon, biogenic opal, calcium carbonate, and iron from sediment core PS97/093-2, all of which are corrected for lateral sediment redistribution (corr-BMAR). To quantify this correction, we explore the relationship between sortable silt as a bottom current strength proxy and 230Th-derived focusing factors as indicators of lateral redistribution of sediments, respectively. Therefore, this dataset includes the following data: Concentrations of export production indicators (opal, Carbonates, Fe, total organic carbon, and excess of Barium), dry bulk density, sortable silt (averaged between tie points), calculated focusing factors, and corrected and non-corrected accumulation rates of export production indicators of core PS97/093-2 over the past 1.4 million years.-70.27467-57.49917South Pacific OceanAustral University of Chilehttps://doi.org/10.13039/5011000098331500003FONDAP-IDEALGerman Research Foundationhttps://doi.org/10.13039/501100001659390741603EXC 2077: The Ocean Floor – Earth's Uncharted Interface
