Koweek (2022): Expected Limits on the Potential for Carbon Dioxide Removal From Artificial Upwelling

This work examines the question: Can pumping of nutrient-rich water from the deep ocean to the surface draw down CO2? The modelling study concludes that artificial upwelling is probably not likely to drawdown much CO2, resulting in very small estimates of CDR potential. Moreover, additional production supported by bringing new nutrients to the surface is almost completely offset by the release of CO2 from deep ocean water.
