New research will assess the efficacy and efficiency of ocean alkalinity enhancement in mitigating climate change and ocean acidification. The University of Hawai‘i at Mānoa oceanographers will lead the research that will involve an experiment that adds alkalinity and tracers to ocean water to test its effect on removing carbon dioxide from the atmosphere. 

The study has received funding from the National Oceanic and Atmospheric Administration (NOAA) and ClimateWorks Foundation worth $1,915,600 for a 3-year period. It is one of the 17 projects that were funded through the recent National Oceanographic Partnership Program (NOPP) investment to better understand marine carbon dioxide removal for mitigating climate change and ocean acidification.

It will be led by oceanography professor David Ho and collaborators from [C]Worthy, Ebb Carbon, UCLA, and American University who will partner with the East Bay Municipal Utility District which operates a wastewater treatment plant that discharges into San Francisco Bay.

The research is critical in assessing how alkalinity released in the ocean removes CO2 from the atmosphere. The scientists will first use a computer modeling framework to design an experiment that includes a release strategy and a sampling plan that will track effects in the environment. 

Following the experiment, the team will conduct an analysis that estimates the efficacy of the alkalinity release in removing carbon from the atmosphere.

“This project represents the first time an alkalinity release will be conducted along with the dual tracer technique and allows us the opportunity to determine the movement of CO2 between the ocean and atmosphere and track the evolution of an ocean alkalinity enhancement… Also delivered through this effort is a demonstration of how we develop tools for monitoring, reporting, and verification of ocean carbon dioxide removal,” explained Mr Ho.

Participating in the research will be also local community members, including tribes, non-governmental and community organizations. The study will take into account their views and priorities, and what associated risks and co-benefits these groups perceive. A public engagement will release the technical work from the research to present it to those communities.
