Sea temperature
The water, measured and modelled
The last seven days and the next two, from three different instruments.
- Farm intake (measured)
- Bay model, surface (OCIMS)
- Bay model, next 48 h
- Satellite (NOAA CoralTemp)
These measure different things. The farm reading is seawater pumped in at New Harbour; the model is a coastal ocean simulation for a point in the bay; the satellite is a 5 km pixel of the surface skin, a day or two behind. Differences of a degree or two between them are normal.
