Abstract:	This data consists of productivity from sediments collected during the ODP Expedition 112m borehole 680A at the Peruvian Margin. Depths are from samples analyzed in Gueguen et al. (2016) and in https://doi.pangaea.de/10.1594/PANGAEA.973695. Productivity was interpolated to the depths using a qualitative curve published by Schrader and Sorknes (1991). Values are qualitative and dimensionless.
