The lab’s longest-running thread, tracing back to PhD work on probabilistic
regional ocean predictions with dynamically orthogonal level-set methods.
Current work applies deep learning to correct systematic biases in global
climate model (CMIP6) projections of sea surface temperature and dynamic sea
level in the Bay of Bengal, detect coastal eddies from high-frequency radar,
and model salinity variability in the Andaman Sea. This pillar is also where
the emerging Neural Data Assimilation direction — physics-informed
architectures for dynamical systems — is most directly applied.
