[Coral-List] drone used to photograph reefs

[Douglas Fenner]

I see I made a mistake in my typing, I meant to type "5 sq km" but typed "5
sq m".  Big difference.  Actually a lot larger than the areas covered by
taking many photos underwater and stitching them together on a desktop
computer.  But still small compared to all the world's reefs.  Apologies
and thanks to the person who pointed the error out.   Cheers, Doug
