TO SPAWN OR NOT TO SPAWN...
In any good romance, timing
is everything. Researchers at the Flower Garden Banks National
Marine Sanctuary hope that recent complications, an early August
moon and a mysterious band of cold water won't put a damper on
this year's coral spawning expected on August 15. First discovered
in 1990 by a volunteer diver, the coral spawning occurs annually
on the eighth day after the first August moon.
Sanctuary staff heading out
on the appropriately named M/V Fling will be looking for the
same "menage a beaucoup" divers have seen for the last
eight years.
Observers in earlier years
describe the still ocean waters suddenly awash in a white bloom
of sperm and egg as an upside down snowstorm. During the coral
spawning, scientists collect the infant corals or gametes as
they float to the surface and transplant them in the laboratory,
with the expectation that laboratory-raised coral reefs will
someday repair damaged reefs.
Scientists believe that the
August moon and warmer waters trigger the annual spawning. This
year's full moon came early in the month on the 7th, and waters
may not be warm enough. Complicating the event is the sudden
appearance of a mysterious band of cold water that is plaguing
the northeast Gulf of Mexico and chilling waters along the Florida
Panhandle.
Just in case conditions are
not conducive to romance this month, sanctuary staff plan to
chaperone the coral reefs again in September.
