Why Report Coral Bleaching?
By reporting coral bleaching, you’re helping research scientists, environmental organizations, policymakers, and community members in Hawaiʻi focus monitoring attention on reefs undergoing increased temperature stress.
Your contributions are important to our understanding of, and response to, bleaching across the main Hawaiian islands.
Coral Bleaching Levels
Coral bleaching is a complex process, so to make reporting more straightforward, we simplified it down to three categories:
Light Bleaching
Light bleaching represents areas where some corals look pale but are not bleach-white.
Medium bleaching
Medium bleaching categorizes areas where small portions of corals are bleach-white.
Severe Bleaching
Severe bleaching is used to describe large areas with bleach-white corals.
