This is to report coral bleaching in the Saudi Arabian reefs at the
Arabian Gulf.  Five coral reefs were visited from August 16 to 20,
1998.  There is widespread bleaching of corals in four patch reefs
(seawater temperature 35.2-35.9°C).  Very high mortality (about 95%) in
Acropora was observed.  Thin layer of brown filamentous algae already
covers Porites, Acropora and Platygyra.
Coral bleaching is minimal at the offshore island reef (seawater
temperature 33.7°C).  Bleached corals are Pocillopora, Acropora, Porites
and Platygyra.
