Product Description

Climate change threatens even the best-protected and most-remote coral reef ecosystems. 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 developed a variety of Thermal History metrics for coral reef management, initially released in July 2014. In the current Version 2.0, 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.

The Version 2.0 metrics were derived from Coral Reef Watch's Version 1.0 CoralTemp daily global 5km (1/20°) SST data product, for the period 1985-2017. Source data for CoralTemp are the NOAA/National Environmental Satellite, Data, and Information Service (NESDIS) operational near real-time daily global 5km Geostationary-Polar-orbiting (Geo-Polar) Blended Night-only SST Analysis; the NOAA/NESDIS 2002-2016 reprocessed daily global 5km Geo-Polar Blended Night-only SST Analysis; and the United Kingdom Met Office 1985-2002 daily global 5km night-only SST reanalysis produced on the Operational SST and Sea Ice Analysis (OSTIA) system.
