Coral Bleaching Risk Indicators and Summer Sea Water Temperatures for the Great Barrier Reef
The graphs on the left side of the page show the number of days exposure to temperatures at or above those indicated on the x-axis and how they compare to bleaching thresholds. Bleaching thresholds are site-specific and are an interpolation of sea surface temperature (SST) and exposure times between warmest non-bleaching summers and coolest bleaching summers. When the time-temperature curve exceeds the predicted bleaching threshold, sensitive corals are in danger of bleaching.
The graphs on the right side of the page show the trends of average daily temperatures against the long-term average. The number of years of data used in calculating the long-term average is shown in the legend.
