Quantifying Measurement, Reporting, and Verification (MRV) Uncertainties in Ocean Alkalinity Enhancement
This research explores the primary technical barriers to accurate MRV in ocean alkalinity enhancement (OAE). It proposes the integration of observational data with predictive modeling to address uncertainties regarding air-sea gas exchange, background ocean variability, and ecological threshold responses.
In plain words
One idea for slowing climate change is to change seawater chemistry so the ocean takes up more carbon. This study asks how to measure more precisely how much carbon is actually removed, so the method can be checked and credited.
Primary research question
How can integrated observation-model frameworks effectively quantify and reduce uncertainties in air-sea gas exchange and background variability to improve the verifiability of ocean alkalinity enhancement?
Knowledge gap
What remains worth asking
There is a need to clarify the relative contributions of physical and ecological variables to MRV uncertainty, as current methods lack the precision required for reliable carbon credit accounting.
Potential contribution
Why it may matter
Improving MRV precision is critical for the viability of OAE as a climate mitigation strategy, as it directly impacts the ability to verify carbon removal and secure regulatory or market-based support.
