WHOI Develops Tool to Predict Coral Bleaching Months Before It Strikes

6/9/2026

By whoi.edu, whoi.edu. A new forecasting tool from Woods Hole Oceanographic Institution could give reef managers and coastal communities a five-to-six-month head start on one of the ocean’s most destructive events: coral bleaching. Called the Bleaching Event Early Predictor (BEEP), the system works by tracking three large-scale climate patterns in… SEE MORE
