Data sets

Benthic foraminifera census counts and compilation of the isotope, grain size, TOC, CaCO3 and XRF data records of sediment core SO236_052-4 Dorothea Bunzel, Gerhard Schmiedl, Sebastian Lindhorst, Andreas Mackensen, Jesús Reolid, Sarah Romahn, and Christian Betzler https://doi.pangaea.de/10.1594/PANGAEA.882514

Short summary

We investigated a sediment core from the Maldives to unravel the interaction between equatorial climate and ocean variability of the past 200 000 years. The sedimentological, geochemical and foraminiferal data records reveal enhanced dust, which was transported by intensified winter monsoon winds during glacial conditions. Precessional fluctuations of bottom water oxygen suggests an expansion of the Arabian Sea OMZ and a varying inflow of Antarctic Intermediate Water.
