Reef area

[Callum Roberts]

Mark Spalding has recently written a paper in which he estimates 
global reef area under three different definitions of a reef (using the 
World Conservation Monitoring Centre's GIS of reef distribution). I 
believe that one of these definitions comes up with the figure of 
230,000km2 mentioned in an earlier posting. I also have a feeling 
that the paper is now in press with Coral Reefs. Mark is currently in 
the field in the Seychelles and so cannot enter this discussion 
himself. His email is:

Mark.Spalding at wcmc.org.uk

I am sure he would be very happy to respond to interested people on 
his return.

Best wishes,

Callum Roberts
