REACT: carbon-first AI framework for consistent marine pH reconstruction
Why it matters for readers: If you care about ocean acidification, REACT shows AI can make more reliable pH maps by respecting carbon chemistry and conservation.
- REACT transports a latent carbonate state with a conservative advection–diffusion solver rather than directly transporting pH, enforcing carbon conservation,1
- A separate source module captures non‑conservative carbon‑cycle variations and a chemical decoder converts the corrected carbonate state into pH constrained by carbonate equilibrium,1
- On simulation data REACT reduced pH NRMSE by 14.7% and chemical consistency error by 24.0% relative to the best baseline,1
- REACT is designed to avoid errors that arise when treating pH as a passive tracer and shows robustness against error accumulation across temporal scale changes,1
