What it calculates
The “Coral Bleaching” calculator computes Heat stress (DHW) in °C-weeks from 3 parameters: sea surface temperature (sst) (°C), maximum monthly mean (mmm) (°C), weeks at this temperature (up to 12).
Estimates environmental impact and carbon footprint.
Example calculation
With parameters Sea surface temperature (SST) = 30.5 °C, Maximum monthly mean (MMM) = 29 °C, Weeks at this temperature (up to 12) = 6 the result is 9 °C-weeks.
How to use
- Enter sea surface temperature (sst), maximum monthly mean (mmm) and weeks at this temperature (up to 12) — each field above is adjustable with a slider.
- Heat stress (DHW) (°C-weeks) is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.
