2007 - Algal Bloom and Fish Kill On Florida Beach
By Hardy Jones
Deborah Cutting, shooting stills, and myself on video got
out of our car at the site of an unusual (for this part of
Florida) fish die-off and red tide event. Immediately our
eyes began to burn and we started coughing. I’d heard
about these occurrences of respiratory and eye irritation
on the Gulf coast of Florida and along the central coast
of California but never had the experience myself. It’s
really odd to know that a toxin generated by a marine algae
is blowing off the water with enough strength to cause respiratory
distress in people walking the beaches and living nearby.
I still have a scratchy throat hours after leaving the site.
See
my blog of August 14, Algae Blooms Threatens Florida’s
Gulf Coast for further information.
Some city employees tried to prevent me from filming the
effects of this Harmful Algal Bloom (HAB) at Houguenot Memorial
Park, a beach east of Jacksonville, Florida. That’s
a bit bizarre until you realize that attractive beaches constitute
much of the life blood of Florida. It reminds me of the town
officials who tried to keep shark warnings from being posted
in the film “Jaws” so as not to discourage tourists.
The fish at the high water mark were a sad sight. A blown
up puffer fish, a needle-fish, mullet, even a baby alligator
- How could that be? – all strewn, wide-eyed, mouths
agape, like rubbish in a huge crescent at the top of the
beach.
We drove north to Fernandina Beach that had been the scene
of a similar event yesterday. But there were few dead fish.
What was clearly visible were the scraping marks of the earth
moving equipment that had just cleaned the beach of the dead
fish, though not their odor still hung in the air.
First indication of the red tide had come from a NOAA satellite
that detected it September 25. Northeasterly winds are moving
the algal bloom south. In a day or so we may not have to
travel more than a mile to see the bloom. It could reach
St. Augustine that soon.
What has caused this bloom? Well, no one knows the specifics
of this one. Experts at the Nassau County Department of Health
say correctly that it’s a combination of water temperature,
salinity and wind direction. But it’s more than that.
These blooms are hugely exaggerated by fertilizers that run
off agricultural land carrying nutrients that magnify the
bloom. Combine a little global warming and you can get a
super-bloom.
Florida real estate values already suffer from the declining
national market, fear of hurricanes and rising insurance
costs. You can add the threat of algal blooms which make
a day at the beach a tearful event.
BTW, these HABs are a global phenomenon, growing more serious
with each year.
UPDATE: By Friday, September 28 the red tide had crossed
the St. John's County border and continues south.
