This is an update of and extension of the MARGO compilation of planktonic foraminifera assemblages for the Last Glacial Maximum (19,000-23,000 ka BP). It includes all data previously compiled within the MARGO project, with some minor corrections (indicated in QCNote), data published since and new counts. The taxonomy has been updated and harmonised to be directly comparable with the ForCenS core top data set (https://doi.pangaea.de/10.1594/PANGAEA.873570; https://doi.org/10.1038/sdata.2017.109). Criteria for inclusion of new data followed those of MARGO, including the ranking of chronological confidence (https://doi.org/10.1016/j.quascirev.2004.07.017). All data pertain to the size fraction >150 µm. Absolute counts are provided whenever these were available; no attempt has been made to correct published relative abundance data when their sum deviated from unity. The data are made available in wide format with metadata with self-explainable headers.
