Melanesia: Bleaching Warning in Fiji-Beqa

Warmer than normal waters continue throughout Melanesian waters.   
Thermal Stress now exceeds 12 degree heating weeks in a large area  
southeast of Samoa and American Samoa.  Workers in this area should  
be watching for localized warming and bleaching.

A smaller area of warm water is directly influencing Fiji and a level  
1 bleaching alert has now been issued for Fiji-Beqa.  The pixel used  
for Fiji-Beqa has now reached 4.6, making bleaching likely.  We  
encourage you to submit reports on the conditions of corals to the  
NOAA-ReefBase bleaching form (below).

According to our past data,  some bleaching is likely at DHW values  
of 4 or above and large-scale bleaching and some mortality is likely  
above 8. We encourage researchers in these regions to watch out for  
signs of bleaching.
