Coral Bleaching Stress: Degree Heating Weeks & Symbiont Loss (2D)

2D coral-bleaching lab: a NOAA-style Degree Heating Weeks thermal-stress integrator drives a real photoinhibition/symbiont-expulsion ODE, with sliders for heatwave intensity, duration, light and water flow so you can watch a coral head lose its zooxanthellae and recover in real time.

This 2D companion turns the same subject as the 3D coral-reef scene into a real thermal-stress model: a rolling Degree Heating Weeks accumulator (the metric NOAA Coral Reef Watch uses operationally) feeds a photoinhibition/symbiont-expulsion ODE, so dragging the heatwave-intensity, duration, light and water-flow sliders drives an actual zooxanthellae population decline and recovery rather than a decorative particle flow.
