marine Carbon Dioxide Removal

In order to avoid anthropogenic global warming of 1.5-2.0 °C, rapid reduction of CO2 emissions

needs to be supplemented with scaled up carbon dioxide removal on land and in the ocean (IPCC 2018). There are several techniques of marine Carbon Dioxide Removal (mCDR), our group is currently focusing on Ocean Alkalinity Enhancement (OAE).

Led by the Pacific Northwest National Laboratory, we are part of a collaborative effort developing model and mesocosm experiments to evaluate the effectiveness and impact of OAE in the Salish Sea (UW), Chesapeake Bay (VIMS), and in the Gulf of Alaska (our group). Our group uses the Gulf of Alaska ROMS-Cobalt configuration for this work. The project started spring 2024 and was funded by the Department of Energy through their Arpa-e program.
