U.S. Virgin Island Potential Bleaching Event - "Heads up"
Anomalously high sea surface temperatures (SSTs) have been developing
over a large area of the North Atlantic Ocean since July and now are
present over most of the Caribbean Sea.
The SST at U.S. Virgin Island has been creeping up above the summertime
maximum monthly mean SST since mid-August and now is approaching the
Our Degree Heating Week chart shows that DHW has stated to accumulate at
U.S. Virgin Island. There is a potential for bleaching if SST continues
to rise in the area.
Any feedback you can provide is useful: both bleaching or non-bleaching
observations, are welcome.
We, NOAA's Coral Reef Watch Project, are developing an automatated coral
bleaching email warning system. The warning is derived based on our
satellite monitoring using satellite HotSpot and Degree Heating Weeks
algorithms. The email will be sent out to region-relevant recipients for
notification at selected reef sites. The list of region-relevant
recipients and list of selected reef sites are under development. A test
message of bleaching watch for Guam is shown below. Please make
comments/suggestions on this automatated email alert, both the content
and mode of
broadcasting how we might send out these warnings.
