# THALWAG Ocean Dashboard

> A live, public chart of the northern Indian Ocean by THALWAG (https://thalwag.com), a research organisation in Kochi, India, building an ocean-observation network from India's fishing fleet.

The dashboard shows, on one interactive chart of the Arabian Sea:

- **Sea-surface temperature** — real, from NASA GIBS (GHRSST MUR L4), decoded to °C, with isotherms every 0.5 °C and a 30-day timeline.
- **Argo floats** — real positions of autonomous profiling floats, via Argovis.
- **Ocean currents** — real modelled surface velocity, from the E.U. Copernicus Marine Service.
- **Coastline and depth contours** — Natural Earth (no political boundaries); 200 m shelf edge, 1 000, 2 000 and 4 000 m.
- **THALWAG sensor nodes** — currently **simulated**: no THALWAG hardware is at sea yet. Every simulated reading is labelled SIMULATED and stored with an is_simulated flag; real readings are labelled LIVE.
