Red Tide on the move

Two related Red Tide reports here and "Bummer" Red Tide is already doing the "Fish Kills" number. Fingers crossed that its brief as I understand there is likely to be a Paddle-Boarding event in the Palm Island vicinity in the not to distant future.

The bloom is heading south and so far we've been lucky in our neck-of-the-woods, although after being out on water today (and preferably staying out) the water quality didn't look that hot and I didn't want to spend to much time immersed in it either.

Is there any particular reason apart from rain fall and probably heavy nutrient load that its back? Let me know if anyone has any pertinent intel



10.12 report:


The Karenia brevis bloom first reported two weeks ago in southwest Florida, currently extends approximately 2 to 12 miles offshore of Charlotte and Lee counties from Gasparilla Pass south to Captiva, with the densest concentrations reported offshore of Cayo Costa. Analysis of water samples also confirmed the presence of K. brevis ranging from very low to medium concentrations in Pine Island Sound (Lee County). Widespread fish kills have been reported offshore in association with this bloom.
Karenia brevis was not detected in water samples collected this week alongshore of Pinellas, Hillsborough, Manatee, Sarasota and Collier counties or offshore of the Florida Keys (Monroe County).


The FWC 10.7 report


Southwest Coast
There is a bloom of Karenia brevis, the Florida red tide organism, along the southwest coast of Florida.  The bloom was first detected last week alongshore of Sarasota County and has since moved south.  Based on satellite images taken on October 6, the bloom was located outside of Charlotte Harbor, alongshore and offshore of Charlotte and Lee counties. Samples collected alongshore of southern Sarasota, Charlotte and Lee counties show concentrations ranging from not present to low, whereas samples collected offshore show concentrations ranging from low to medium.  The highest concentrations were detected in samples collected within the bloom patch approximately 3.8 miles southwest of Bocilla Island (Charlotte County) on October 5.

Bloom Boundary: This week, Karenia brevis abundance was greatest in the southern regions of southern Sarasota County, Charlotte and Lee Counties, consistent with the southward movement of the bloom.  Based on satellite images from October 6, the bloom extended approximately 15 miles offshore and 20 miles alongshore of Charlotte and Lee Counties.


Northwest Coast
Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Walton, Bay and Levy counties or offshore of Taylor County.


East Coast
No samples were analyzed this week from the east coast of Florida.
