Structure
📅 Day 1 – Introduction to AI for Ocean Currents & Sensing
- Ocean Observations 101: Buoys/DART, HF radar, satellite altimetry (SSH)
- Data Formats & Access: NetCDF/Zarr, coordinates, gridding to coastal domains
- Physical Basics: shallow-water intuition, bathymetry, boundaries
- ML Landscape: baselines (persistence/AR), PINNs vs Neural Operators (FNO)
- Hands-on: Access small buoy/HF radar/altimetry samples; run quick QC (spike/flatline/time); align & grid into a tidy dataset
- Hands-on: Train a tiny PINN on synthetic wave probes; run a minimal FNO for +6 h surface-current forecast vs persistence
📅 Day 2 – Forecasting, Data Assimilation & Uncertainty
- Data Assimilation Essentials: EnKF/3D-Var intuition, increments, observation error
- Sequence Models for Marine Time Series: encoder–decoder transformers, SSMs; masking & missing data
- Uncertainty & Calibration: ensembles, heteroscedastic outputs, conformal prediction; coverage & CRPS
- Hands-on: Assimilate an HF-radar snapshot into yesterday’s state and visualize analysis increments
- Hands-on: Build a compact encoder–decoder for buoy streams (+24 h horizon) and add conformal bands; verify nominal coverage
📅 Day 3 – Tsunami Detection, ETA & Operational Alerts
- Tsunami Detection from DART/Tide Gauges: detrending, anomaly scoring, robustness to noise/clock drift
- ETA Estimation & Communication: uncertainty bands and practical reporting
- Operational Workflow: ingest → QC → assimilation → forecast → UQ → post-process → publish
- Alert Design: precision–recall vs ROC, class imbalance, cost–loss analysis, tiering (Advisory/Watch/Warning)
- Hands-on: Detect tsunami-like anomalies and estimate ETA with uncertainty
- Hands-on: Wire a mini pipeline (configs/CLI) to produce alerts; pick thresholds from PR curves and export a one-page situation report (maps, bands, alert level)
