Description:
Abstract:
The Tropical Ocean Coral Bleaching Indices web page provides coral bleaching related thermal stress information extracted from Coral Reef Watch's twice-weekly near-real-time 50-km satellite nighttime AVHRR sea surface temperature (SST) and derived coral bleaching HotSpots and Degree Heating Weeks (DHWs) datasets for 24 selected reef sites. The satellite data are extracted from the 50 km satellite pixels nearest to the 24 selected reef sites. The data at these satellite pixels are assumed to best represent the conditions at the corresponding reef sites. On the page, the following information is provided for Ningaloo, one of the 24 sites: reef site name, current thermal stress level, current DHW value, the historical maximum DHW value at the location since 1985 and the year of the occurrence, current AVHRR nighttime SST value, and the Maximum Monthly Mean sea surface temperature climatology value. All the reef names are linked to corresponding maps showing the latitude-longitudes and locations of the pixels and their associated reef sites. Links to other useful information are also provided on the map pages. Five thermal stress levels are defined by Coral Reef Watch to scale the intensity of thermal stress, from no-stress, bleaching watch, bleaching warning, to bleaching alert level 1 and 2. These levels are defined in terms of the HotSpot and DHW values (see <http://coralreefwatch-satops.noaa.gov/SBA.html>). When thermal stress is present at a reef site, i.e., current SST exceeds the Maximum Monthly Mean SST Climatology at the site, a triangular warning icon is added to that reef site and the status text is displayed in red color. A Bleaching Warning is issued when the current SST reaches 1 degree Celsius over the maximum monthly mean SST climatology. At this point, DHWs begin accumulating and a larger triangular icon is displayed. An accumulation of 4 DHWs triggers a Bleaching Alert Level 1 and the status is displayed in bold red text. An accumulation of 8 DHWs triggers a Bleaching Alert Level 2. See <http://coralreefwatch.noaa.gov> for more information. Satellite data from the Advanced Very High Resolution Radiometer (AVHRR) on NOAA's Polar Orbiting Environmental Satellite (POES) are used to generate AVHRR-SST. The most recent AVHRR data obtained from the POES that is presently in operational mode are processed to generate the near-real-time SST data used to create the coral bleaching HotSpots and DHWs. The SST data, coral bleaching HotSpots, DHWs and DHW chart are produced twice-weekly on every Tuesday (using AVHRR data from the previous Saturday through Monday) and on every Saturday (using AVHRR data from the previous Tuesday through Friday).
Purpose:
NOAA's Coral Reef Watch (CRW) initiative seeks to fully utilize space-based sea surface temperature (SST) observations combined with in-situ data to continually monitor for early indications of thermally- induced coral reef bleaching worldwide. As part of CRW, the NOAA/NESDIS Coral Reef Monitoring Program developed a suite of products including two-dimensional global SST, SST Anomaly, coral bleaching HotSpots as well as coral bleaching Degree Heating Weeks as indices of coral reef bleaching related thermal stress. To provide more focused services to local reef communities and scientists, the NESDIS Coral Reef Monitoring Program developed this twice-weekly satellite near real-time "Tropical Ocean Coral Bleaching Indices" Web page as well as SST time series to deliver collective thermal stress information for selected reef sites. Through this Indices web page, NOAA/NESDIS provides actual SST, HotSpot, and DHW numerical data for coral bleaching monitoring and assessment.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Polar Orbiting Environmental Satellite (POES) AVHRR-SST values are accurate to within 0.5 degrees C and adjusted by in-situ information (buoys) to best-approximate SST at a depth of 1 meter. However, to provide a complete global coverage, estimation of SSTs at all pixels that are cloud covered may occasionally reduce the accuracy of SST at these pixels. The accuracy of the DHW depends on both SST and the SST climatology used for deriving DHW. No estimation on the accuracy of DHW has been done yet.
