Product Description

Climate change threatens even the best-protected and most-remote reefs. Reef management in the face of climate change must incorporate how various factors (e.g., benthic structure, currents and local upwelling, connectivity, herbivore abundance, thermal history) affect coral and reef ecosystem resilience. Research over the last decade indicates that thermal history is among the most important factors influencing coral reef resilience.

With support from the NOAA Coral Reef Conservation Program, Coral Reef Watch has developed a variety of Thermal History metrics for coral reef management. Several Sea Surface Temperature (SST) metrics are calculated for reef-containing locations and adjacent waters and are arranged into six themes: Stress Frequency, Stress Onset, SST Variability, SST Trend, Climatology, and Annual History.

These metrics were derived from the Pathfinder v5.2 ~4km (1/24°) daily SST dataset, for the period 1985-2012, provided by the Group for High Resolution Sea Surface Temperature (GHRSST) and NOAA's National Centers for Environmental Information (NCEI). The Pathfinder project was supported in part by a grant from the NOAA Climate Data Record (CDR) Program for satellites.
