Abstract

Increasing sea surface temperature (SST) and its consequences on marine ecosystems are widely discussed. Andaman Sea witnessed a few bleaching events during 1998, 2002 and 2005. The present study was taken up to assess the extent of bleaching during 2010 in selected reef sites in the Andaman through line intercept transect survey. It was found that the fully bleached corals as a percentage of total coral cover were maximum at Havelock Island (69.49), followed by South Button Island (67.28), Nicolson Island (56.45), Red Skin Island (43.39), North Bay (41.65) and Chidiyatapu (36.54). Branching corals were the worst affected, whereas the massive corals were found to have relatively withstood the elevated SST. The status of reefs and the variability in bleaching with the progression of SST with respect to different coral species are discussed.
