Sea Surface Temperature (SST) derived from the NOAA AVHRR satellite data were used to
generate the Degree of Heating Weeks (DHW) and Hot Spot (HS) products. Combination
of the cumulative temperature anomalies and the thermal stress studies were yielded to
synoptically identify the probable areas of bleaching. The bleaching status of the Andaman
region was assessed based on the DHW and HS for the bleaching event occurred in the
Andaman region in April/May 2005. The bleaching status up to Alert Level-1 was recorded
with the maximum HS of 3oC and DHW 6oC-week. Simultaneous in-situ reef observations
conducted in the Andaman Sea confirmed the coral bleaching event. The maximum mortality
in the region due to coral bleaching was shown by the Acropora species (43%) followed
by Montipora species (22%) and Porites species (14%). This study focused on detection of
coral bleaching warning based on the SST in compliment with the in-situ observations.
