“Advancing Marine Carbon Dioxide Removal with Ocean Alkalinity Enhancement”

In the endeavor to combat climate change, my research centers on evaluating ocean alkalinity enhancement (OAE) as a method of marine carbon dioxide removal (mCDR). By harnessing carbon isotopes and sophisticated biogeochemical modeling, including the use of regional ocean modeling systems (ROMS), I delve into the intricacies of the marine carbon cycle. This investigation aims to assess the feasibility, effectiveness, and environmental safety of OAE. Through meticulous modeling exercises, I examine the potential impacts of alkalinity enhancement on ocean chemistry and ecosystems, striving to identify the conditions under which OAE can be most beneficial for carbon sequestration without compromising marine health. My work stands at the forefront of mCDR research, offering critical insights into the potential of OAE to serve as a sustainable solution to atmospheric CO2 removal, thereby contributing to the broader goal of mitigating global climate change.

ABSTRACT

My work focuses on advancing our understanding of marine carbon dioxide removal (mCDR) through the lens of ocean alkalinity enhancement (OAE). Utilizing carbon isotopes and biogeochemical modeling, I evaluate the safety, efficacy, and detectability of OAE strategies to inform sustainable climate solutions.
