A Global Compilation of 14C/13C-Based Ocean Net Primary Productivity Dataset

This archive contains a global compilation of marine net primary productivity (NPP) measurements derived from bottle incubation experiments using radioactive or stable carbon tracers (14C or 13C). All NPP estimates are reported as depth-integrated values within the euphotic zone. The database includes sampling date, geographic coordinates, integration depth, depth-integrated NPP, measurement method, data source, and reference information. The dataset was compiled to support the evaluation and development of satellite-based and data-driven marine productivity models and to improve observational constraints on the global distribution of ocean primary productivity. Chen, X., Huang, Y*., Liu, H., Cassar, N., Liu, X., Wang, W., Chai, F., Kang, J., & Huang, B. (2026). Reduced estimate of global marine primary productivity and hemispheric redistribution over the satellite era revealed by an expanded global observational database.
