Hi all,

Here at Looe Key we've seen one odd Montastrea faveolata releasing  
bundles on the night of 5th; the rest were not doing anything at all  
(from Aug 1 to 6). On the same night (Aug 5) Montastrea cavernosa  
spawned prodigiously starting from sunset (about 8 pm) and continuing  
well after 10 pm. We've seen lots of males, but only two females  
releasing gametes.

Funny thing: on August 6 A. palmata went again (10:30 pm). The first  
A.palmata dribble was on the night of Aug 2 and then nothing until  
Aug 6. This night it looked like most of the colonies found at the  
site (Looe Key, buoy 10) were spawning, although it commonly was only  
part of the colony spawning.

Really looking forward to the summary posting, Alina!
