Jan 5 2002 - checked reef crest after getting reports from tourists of
in the intertidal - found bleached corals from intertidal to 10 m at several
sites around Heron Island on the southern Great Barrier Reef.  Rough visual
estimates - approximately 10-20% of the corals on the reef crest and slope
to 10 m) are affected strongly. Acroporas are mainly affected at this point
although there is a general paling of most species. Pocillopora, Stylophora
Seriatopora are among the next most affected species. Water temperatures
that Heron Island is warm - and that we are at least at the broad bleaching
threshold for this region.
