A week ago I went to a presentation in the British Virgin Islands
given by the guys on the research vessell currently working in the
Caribbean.
One of the issues that fascinated me is that there was mention that
at times the currents carrying waters from the Orinoco and Amazon
rivers at times bring those waters far enough north that they can be
monitored on the southern edges of the Virgin Islands. Having
sailed many times from the BVI to Venezuela I had used the change
in color of the water from the deep clear Caribbean Blue to the
clear brown/green color as in indication that I was getting into the
nutrient rich waters coming from the Orinoco. I would then expect
the current to increase and almost the instant we hit the change in
water color
there would be dolphins and our fishing line would start buzzing and
we could get all sort of good things to eat. Usually that change
in
water was about 250 miles south of the BVI.
So now not quite a week after that discussion we have a green water
event here in the BVi. I have never seen the water this color
before
( I have been here 20 years)- and it looks like the color of water
one would expect to find around Grenada or Los Testigos.
Yesterday - Tuesday 21 April 09 I was on the north side of the BVi
snorkeling around Monkey point on Guana island - Water temp was
76.8 which is cool for this time of year - but water temps are down.
Water was clear blue as usual and visibility down a bit because of
a recent northerly swell. I then went down Sir Francis Drake
Channell to the Bight on Norman Island. I took my clients out to
the Caves for a late afternoon snorkel. A big pod of dolphin came
around - unusual for here - and i noticed the water was quite
green. My clients got in the water and immediately started getting
stung by jellyfish. I did not see what was hitting them, but I
was in the water too and there was almost zero visibility and the
water a very ususual green color. On returning to the boat in the
Bight I saw the water temp was up to 80 degrees F. - ( a 3.5deg F
increase from the north side of Tortola). It seems that everyone is
getting hit by jellies of some sort. Divers at the Rhone yesterday
said the water was green - no vis, but huge feeding frenzies going
on such as they had never seen at the Rhone. Another charter boat
emailed in saying the water looks just like it does normally in
Grenada.
I just wanted to alert NOAA to this as I find the phenomena
interesting, and feel someone should be taking samples of the water
for analysis - . I have written again to boats out chartering to
tell them to note water temps and any unusual sightings. It would
be interesting to see if you detect this from satellite photos - I
wanted to get in touch with the guys on the research vessell but
understand that they are already down island???
Please let me know you have received this and any explanation NOAA may have

Islands. Reef Check coordinator BVI
