How to Use This Calculator

Enter the coral colony extension rate in mm per year from annual density band counts.
Input sea surface temperature (°C), salinity (ppt), and light intensity (mol photons/m²/day).
Set the species to apply species-specific growth constants.
Review the projected skeletal density and calcification rate in g/cm²/year.
Compare current growth rates to historical baselines to quantify climate-driven declines.
