[Coral-List] Bleaching conditions continue in western Pacific and around Florida

Abnormally warm waters continue in two regions of the western
Pacific. Warming has continued the region from the northern
Philippines to the southern half of Taiwan. Reports from Kenting
National Park, Taiwan suggest that this is the worst bleaching in
that region since 1998. NOAA Coral Reef Watch data continue to
indicate sea surface temperatures of 30-32 degrees; Coral Bleaching
HotSpots reveal water temperatures of up to 2.4 degrees above the
maximum monthly mean; and the accumulated thermal stress off the
Luzon coast now has reached 15 degree-C weeks.
Another large region of heat stress extends from the Sea of Japan
across Japan into the Pacific north of the Northern Mariana Islands.
Fortunately, this is north of most major reef development. The
warming also extends south spanning the region between Kyushu and
Shanghai and surrounding Chejudo Island. This area has HotSpot
values up to 2.2 degrees and thermal stress of 7.2 degree-C weeks.
Temperature anomalies have dropped south of there, bringing a bit of
relief to the Ryukyu and Yaeyama Islands where mass bleaching has
already been reported.
The bad news is that waters around the Florida Bay and the waters off
the western Bahamas continue to warm. Degree Heating Week values
have reached 8.8 for the Sombrero Reef Virtual Station. We expect
thermal stress at that site to reach a record level next week. With
hurricane Dean likely to pass south of Cuba, little cooling relief is
likely at this time.
We have a new experimental Florida page that is serving as a model
for other regions of the globe. We expect to have a Caribbean page
up shortly with more to follow. The Florida page is at: http://

Coral List and to ReefBase at http://www.reefbase.org/contribute/
