Interactions between ocean alkalinity enhancement and phytoplankton in an Earth system model
Abstract. The functioning and efficiency of ocean alkalinity enhancement (OAE) as a CO2 removal strategy is well investigated in model studies, but risks for the ecosystem are presently not considered...

Our best strategy for assessing the efficacy of ocean alkalinity enhancement (OAE) involves running computationally expensive climate models. Here, we developed a statistical technique that encapsulates the climatic response to OAE interventions, simplifying the OAE carbon accounting problem. 🌊🧪
Impulse response functions as a framework for quantifying ocean-based carbon dioxide removal
Abstract. Limiting global warming to 2 °C by the end of the century requires dramatically reducing CO2 emissions, and also implementing carbon dioxide removal (CDR) technologies. Ocean-based CDR throu...

Do bubbles matter for ocean carbon uptake? 🌊🫧
Yes, especially for local CO2 fluxes, where wave breaking can enhance variability by up to 40%. That’s an important consideration for #mCDR, where fluxes could otherwise be miscalculated. More in our paper here: [https://doi.org/10.1029/2024GB008382]
