πͺΈ Overview
First unified framework for coral reef health
"Coral reefs are not passive habitats β they are active, physics-governed engineering systems with quantifiable input rates, energy conversion efficiencies, structural tolerances, and failure thresholds."
CORAL-CORE is a comprehensive physics-based framework integrating eight governing parameters to decode the extraordinary engineering capacity of stony coral reefs. The framework characterizes coral reefs as self-assembling chemical-mechanical factories converting dissolved calcium ions into hierarchically structured, wave-resistant aragonite architecture.

calcification_rate()
Calculate calcification rate using power-law kinetics
from coralcore.parameters.calcification import calcification_rate
rate = calcification_rate(
omega_a=3.4,
phi_ps=0.65,
temperature=28.0,
t_thr=31.5,

print(f"Rate: {rate:.3f} mmol/cmΒ²/day")
ReefHealthIndex()
Compute Reef Health Index from eight parameters
from coralcore.rhi.composite import ReefHealthIndex
rhi = ReefHealthIndex()
params = {
'g_ca': 1.84, 'e_diss': 91.0, 'phi_ps': 0.67,
