Editing Coral bleaching severity index (section)

== Monitoring and Measurement ==
Monitoring of coral bleaching severity involves in situ surveys, remote sensing, and compilation of observational data into global databases. Scientific institutions and research programs employ standardized field protocols to assess bleaching extent and intensity on coral colonies and reef assemblages. These assessments record the proportion of bleached coral, bleaching intensity categories, and recovery status. Remote sensing technologies, including satellite-derived sea surface temperature anomalies and marine heatwave detection, provide contextual environmental data that correlate with observed bleaching events. The integration of these methods enables temporal and spatial tracking of bleaching severity at multiple scales.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
