[Coral-List] A Swim Through Time on Carysfort Reef; EFFORT TO ASSEMBLE A LIST OF REMAINING HEALTHY CARIBBEAN CORAL REEFS

Tue Jul 28 13:03:00 UTC 2020

Alina - I was part of that 1981 group with Tom Bright at Carysfort Light.
It was with mixed feelings thatI had to leave a couple weeks early to
attend my wedding!  Still, looking back, it was such a privilege to see
such a seemingly healthy place just a few years before the coral world
changed so dramatically.

I like the idea of hearing about places that haven't changed much since the
70s or before.  I'll put the Flower Garden Banks out there.  The earliest
dives and pictures there were in the early 60s and the first measurements
of coral cover in the early 70s.  Very little has changed, though
macroalgae is more persistent since the *Diadema *dieoff.  Coral cover,
which when first measured was just under 50% on the reef caps, is now
closer to 60%.  There are lionfish, but impacts to native fish are not
evident yet, and they are trying to control abundance with culling.  It is
certainly not without threats, but the banks seem to benefit from their
isolation.
