He and Tyka [Preprint]: Limits and CO2 equilibration of near-coast alkalinity enhancement

Jing He and Michael Dominik Tyka IN: EGUsphere [preprint], https://doi.org/10.5194/egusphere-2022-683, 2022

The authors study critical questions which determine the scale and viability of OAE (Ocean Alkalinity Enhancement): Which coastal locations are able to sustain a large flux of alkalinity at minimal pH and ΩArag (aragonite saturation) changes? What is the interference distance between adjacent OAE projects? How much CO2 is absorbed per unit of alkalinity added? How quickly does the induced CO2 deficiency equilibrate with the atmosphere? The preprint is open for discussion.
