This dataset concerns information on the living (rose Bengal stained) benthic foraminifera that was compiled from four independent datasets.They comprise 53 samples from the Peruvian continental margin from water depths of 48 to 2092 m between 1°45'S and 17°28'S that were collected during independent expeditions; in 1998 during Panorama Expedition, Leg 3a, with R/V Melville, in 2008 during R/V Meteor expeditions M77 Leg 1 & 2, in 2009, 2010 and 2011 onboard R/V SNP 2 and José Olaya Balandra and in 2017 during R/V Meteor expedition M137. The surface sediment samples in all studies comprise the topmost 10 or 30 mm. Dataset also presents in situ measurements of bottom water oxygen content and calculated values of Particulate organic carbon rain rates.
