[Preprint] Bach: The additionality problem of Ocean Alkalinity Enhancement
Lennart Thomas Bach IN: Biogeosciences Discuss. [preprint], https://doi.org/10.5194/bg-2023-122, in review, 2023
So far, feasibility studies on OAE (Ocean Alkalinity Enhancement) have mainly focussed on enhancing alkalinity in the oceans (COAE) but not primarily how such anthropogenic alkalinity would modify the natural alkalinity cycle (∆Cbaseline). Here, the author present incubation experiments where materials considered for OAE (sodium hydroxide, steel slag, olivine) are exposed to beach sand to investigate the influence of anthropogenic alkalinity on natural alkalinity sources and sinks.
