The BENFEP_v2 database represents an upgraded version of the "BENthic Foraminifera quantitative database from surface sediments of the Eastern Pacific" (BENFEP_v1,https://doi.org/10.1594/PANGAEA.947086). In this new version we have added five new quantitative datasets and amended the geolocations of a few samples. The taxonomy of benthic foraminiferal species has been updated to World Foraminifera Database (Hayward et al., 2023, last access: 31 July 2023). BENFEP_v2 is presented in a long format. Column codes and column names can be found in the related manuscript (Diz et al.,2023).
