Dear Coral-listers,

We are currently developing new tools to allow users to view our new 5-km products for regions of interest.  In the meantime, we have just set up a page that contains all of our 5-km products for Florida.  You can find these at:

The Bleaching Alert Area and Seasonal Outlook are available for several other jurisdictions (most in US) at:

The NOAA Coral Reef Watch (CRW) experimental daily global 5 km (0.05 degree exactly) satellite coral bleaching thermal stress monitoring product suite presented here is a new-generation version of the current operational twice-weekly 50 km (0.5 degree exactly) monitoring product suite. The new 5-km products are built using NOAA’s new operational 5-km SST products that utilize a constellation of polar-orbiting and geostationary satellites, providing much greater data density than our older 50 km products, despite 100x greater spatial resolution.

We would appreciate any comments or suggestions on these new products. Please send comments to: coralreefwatch at noaa.gov
