Two cores, GeoB18303-2 and 18304-1 were collected using a marine vibrocorer during cruise M102 offshore Durban, South Africa in December 2013. These were collected under the auspices of the joint German-South African project Regional Archives for Integrated Investigations (RAIn), in order to examine climate changes on the east coast of South Africa. Core GeoB18303-2 was acquired at 29° 49,84' S 31° 9,73' E in a water depth of 67.9 m. Core GeoB18304-1 was acquired at 29° 49,14' S 31° 7,62' E in a water depth of 39.2 m. The cores were analysed for downcore elemental chemistry and grain size trends using a Panalytical Epsilon 3 XL XRF machine at the University of Bremen, Germany. Both terrigenous and bulk grain sizes were analyzed using a Coulter laser particle sizer LS 13 320 at the MARUM, University of Bremen, Germany. The quantitative XRF data for Cores GeoB18303-2 and GeoB18304-1 are displayed as weight percentage (wt%) at 5 cm intervals with depth down core. The grain size (bulk and clastic) data for Cores GeoB18303-2 and GeoB18304-1 are displayed as phi values at 5 cm downcore sample resolution.

This dataset has been carefully reviewed and curated in accordance with PANGAEA's exceptionally high quality standards. However, due to discontinued communication from the authors' side, it did not receive the usual formal approval by the authors and therefore lacks final scientific validation.
