This dataset provides planktonic foraminifera assemblage data from the high-resolution marine sediment core MD07-3100 recovered at 41°S in the Southeast Pacific Ocean. The dataset includes relative abundances (%), fragmentation (%), and associated standard errors based on 109 samples analyzed at a temporal resolution of 0.1–2 ka. The record covers the last 20.7 ka. The sediment core was retrieved using a CALYPSO piston corer during the MD159 PACHIDERME cruise aboard the R/V Marion Dufresne. The data support paleoceanographic reconstructions of the last glacial–interglacial period.
