Metocean Foresight System

Ocean temperature forecasting,
at the edge of what's possible.

An AI-driven forecasting system for short- and long-horizon temperature prediction across the South China Sea and the Yellow Sea. Three sites. Four depths. One-hour to thirty-day horizons. Evaluated on reanalysis hindcasts and cross-dataset out-of-sample tests.

The approach

Built on a state-of-the-art Transformer architecture — the same family that powers today's most advanced AI systems — purpose-tuned for ocean temperature. Each site and each depth gets its own dedicated model, so forecasts reflect the physics of where it matters. One unified service serves every station and every horizon through a single, station-aware endpoint.

The experience

Pick a site, pick a depth, pick a horizon — get a forecast in seconds. Every prediction is held up against observed measurements where available, so you see not just the forecast but how much to trust it. Built for ocean engineers, planners, and decision-makers who need answers now, not after a batch run.
