Hi John,

Those observation sounds correct...

NOAA's Degree Heating Week Charts showed no thermal stress accumulations until mid-late July...beginning in the north and expanding down the chain....


or.... if access is slow look at DHW chart for July 12:

and then compare with August 12 [one month later]:

16N -- your location...is about DHW = 3 in august and continues about that accumulation even now....its areas to the north that experienced much higher levels.

As you know FDM is in the Northern Marianas between Saipan and Anatahan.  Interestingly, we saw no indication of bleaching at that time.  Do you know how far south in the Mariana chain bleaching was observed by the folks on the Sette?

The northern most islands had a higher percentage of bleaching (based on visual observations), however benthic video transects and coral community data were collected too, and not analyzed yet.  The coral community on many of the northern islands indicate that there may have been a previous disturbance(s) based upon skeletons covered with new reef growth.  Could this have been a result of the June/July 2001 thermal event that was noted in the Saipan Lagoon?  Any information is appreciated.
