Karenia brevis, starting to pop up in samples

Southwest CoastKarenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Pinellas, Hillsborough, Manatee and Charlotte counties. One sample collected each alongshore of Lee and Collier counties, two samples collected alongshore of Sarasota County and one sample collected offshore of Pinellas County contained background concentrations of K. brevis. Samples collected last week just offshore between the Pavilion Key and Ponce De Leon Bay areas (northern Monroe County) contained concentrations of K. brevis ranging from low to medium.

Bloom Boundary: Sample analysis confirmed patchy concentrations of Karenia brevis last week in southwest Florida just offshore of northern Monroe County between the Pavilion Key and Ponce de Leon areas.  Recent satellite images suggest the continued presence of a small bloom in this area.

 

Northwest CoastKarenia brevis, the Florida red tide organism, was not detected in water samples collected this week offshore of Dixie and Hernando counties.

 

East CoastKarenia brevis, the Florida red tide organism, was not detected in water samples collected this week in the Indian River Lagoon system (Brevard County) or alongshore of Volusia and Dade counties.

Red Tide report

The red tide organism, Karenia brevis, was not detected in water samples collected so far this week in the Indian River Lagoon (Brevard County) or offshore of Hernando and Dixie counties.  On the southwest coast of Florida, one sample collected alongshore of Sarasota County (out of 21 total samples) and one sample collected alongshore of Collier County (out of 9 total samples) each contained background concentrations of K. brevis.  Two samples collected late last week offshore of Pavilion Key (northern Monroe County) contained medium concentrations of K. brevis.

Red Tide report for the Gulf Coast

Yesterdays report from via FWC — Background concentrations of K. brevis were detected in one sample collected alongshore of Sarasota County.  Yet, with medium to high concentrations of K. brevis present last week along Lee and Collier counties, it is possible that patches are still present in unsampled (offshore) areas of these regions.

The Karenia brevis bloom that has been present in southwest Florida for the past several months was detected late last week and early this week in water samples collected offshore and south of the Cape Sable area (Monroe County).  Samples in this area ranged in concentration from medium to very low.  One sample collected this week at Goodland Bridge (southern Collier County) also had very low concentrations of K. brevis.

Karenia brevis was not detected in water samples analyzed so far this week alongshore of Pinellas, Hillsborough, Manatee, Charlotte, Sarasota and Lee counties, in the Indian River Lagoon (Brevard County) or alongshore of Levy, Flagler and St. Johns counties.

Red Tide diminishing

Red Tide is diminishing at long last; the latest report via FWC

Southwest Coast
The Karenia brevis bloom which has been present in southwest Florida for the past several months was only detected this week in two alongshore areas. Very low concentrations were detected at Lighthouse Beach and Lovers Key State Park (southern Lee County) and very low to low concentrations were found at Caxambas Pass, South Marco Beach and Goodland Bridge (southern Collier County).
Karenia brevis was not detected in water samples analyzed this week alongshore of Pinellas, Hillsborough, Manatee, Sarasota and Charlotte counties or alongshore of the Florida Keys (Monroe County) and offshore of Sarasota County.

Bloom Boundary:  Sample analysis confirms that the K. brevis bloom is present in small patches alongshore of southern Lee County and southern Collier County at very low and low concentrations.

Northwest Coast
No samples were analyzed this week for the Northwest coast of Florida.

Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week in the Indian River Lagoon system (Brevard County) or alongshore of Dade County

More Red Tide and Nutrient Load for Florida? HB 421

I find it pretty "mind-boggling" that under consideration are potential changes to allow for an increase of nutrients into the water-ways of Florida after what we have had to endure with the likes of the BP disaster and the effects on tourism, fishing and sports fishing industry etc, etc.

After all of the extensive pro-active measures that Sarasota County implemented; Florida on a State level is actually considering removing the local ability to address these issues, then I guess as we have to remedy the ramifications on a local basis and get landed with the costs too.

Do we really need to take a chance of exasperating the situation let alone the remedial costs incurred by a severe out break of Red Tide or waterway pollution, be it travel industry or on a local basis? The incalculable cost to wild life and health associated to polluted algae laden waters. What I'm I missing here? Common sense?

Still there... Red Tide bloom in SW Florida

via FWC The Karenia brevis bloom present in southwest Florida has been documented so far this week in waters between southern Lee County and Collier County. Low to high concentrations of K. brevis have been detected alongshore of Sanibel Island and background to medium concentrations have been detected alongshore and inshore of Marco Island. In between Sanibel and Marco islands, background to very low concentrations of K. brevis were detected. While K. brevis concentrations are patchy along the southwest coast, satellite images suggest that the bloom is present from southern Lee County south to Cape Sable (Monroe County).

Additionally, samples collected early last week alongshore and offshore of the Atlantic side of the Florida Keys revealed concentrations of K. brevis ranging from background to medium.  Due to the fact that K. brevis has not been detected in this area in association with the current bloom, today’s map includes these data points.

Karenia brevis was not detected in water samples analyzed so far this week alongshore of Pinellas, Hillsborough, Manatee, Sarasota, Charlotte, Citrus, Levy and Taylor counties, in the Indian River Lagoon (Brevard County) or offshore of the Florida Keys (Gulf side).

 

Sampling will continue this week, and complete results will be available in the next scheduled status report on Thursday, December 22.

Persistant Red Tide in SW Florida

Regrettably it seems we're back to a persistent Red Tide again and its not going to help the tourism industry with the respiratory irritation factor. 


Whats changed to cause this? Heavy nutrient loads again?


latest sampling report via the FWC

The Karenia brevis bloom present in southwest Florida has been documented so far this week in waters between southern Lee County and Collier County. Low to high concentrations of K. brevis have been detected alongshore of Sanibel Island and low to medium concentrations have been detected alongshore of Marco Island. The bloom most likely continues south to northern Monroe County as detected by last weeks samples, although no samples have been processed so far this week from that area. Fish kills and respiratory irritation have been reported in conjunction with this bloom in multiple locations this week including Marco Island and Naples.

Karenia brevis was not detected in water samples analyzed so far this week alongshore of Pinellas, Hillsborough, Manatee, Sarasota and Charlotte counties or offshore of Palm Beach County.

 

Sampling will continue this week, and complete results will be available in the next scheduled status report on Friday, December 16.

Red Tide update

Southwest CoastThe Karenia brevis bloom present in southwest Florida currently extends from southern Lee County through northern Monroe County. The highest concentrations of K. brevis have been reported alongshore and offshore of Sanibel Island south to Naples Bay.  Very low to medium concentrations have been reported alongshore and offshore of southern Collier County south to Pavilion Key (Monroe County). In inshore waters, samples confirm up to high concentrations of K. brevis in southern Pine Island Sound and San Carlos Bay (Lee County) and up to medium concentrations inshore of Marco Island (southern Collier County). Multiple fish kills (alongshore and offshore) and respiratory irritation have been reported in the bloom areas of southern Lee through Collier counties.

Red Tide report

Southwest CoastA bloom of Karenia brevis, the Florida Red Tide organism, has been detected in samples collected alongshore of northern Collier County. This bloom is likely a continuation of the bloom reported late September through early November, although this is the first report of alongshore detection in several weeks. Medium to very low concentrations of K. brevis were measured alongshore of the bloom patch, which has been approximated with the use of satellite images to be 25 miles long and extending offshore approximately 15 miles. In locations outside of the bloom, K. brevis was not present or was present only at low concentrations.

 

Karenia brevis was not detected in samples collected alongshore of Hillsborough, Pinellas, Manatee, Sarasota and Charlotte counties or alongshore and offshore of the Florida Keys (Monroe County).

Karenia brevis background concentrations

Yay, I've almost caught up with my postings! Water clarity is dramatically improving almost back to idyllic turquoise blue and Karenia brevis is only showing up in minimal concentrations. I guess I'd better find a clear water pic to be fair. Anyone have some good ones that I can use?

Southwest CoastKarenia brevis, the Florida Red Tide organism, was not detected at bloom concentrations in samples collected this week along the southwestern Florida coast. Background concentrations were observed alongshore of Charlotte County and background to very low concentrations were detected alongshore of Collier County. Karenia brevis was not detected in samples collected alongshore of Hillsborough, Pinellas, Manatee, Sarasota and Lee counties or offshore of the Florida Keys (Monroe County).

Red Tide in San Diego

I just saw this Tweet (AllardPPC) coming over with an article from the NY Times... I had no idea that San Diego has its own form of Red Tide!

Victoria Roberts

Q. Recently, at the San Diego ocean beach at night, we watched light emanating from every wave crest. News reports said it was caused by the red tide. How does it work?

A. The red tide in San Diego this fall was caused by a bloom of billions of a microscopic organism called a dinoflagellate, said Peter J. S. Franks, a professor at the Scripps Institution of Oceanography there.

“The particular species, Lingulodinium polyedrum, is bioluminescent — that is, it can make its own light,” Dr. Franks said.

“An enzyme, luciferase, and a substrate, luciferin, are held in tiny bags called vesicles inside the cell,” he said. “When the cell is jostled — for instance, by a breaking wave or a fish swimming by — the bags burst open, and the luciferin and luciferase mix, creating a flash of bluish light. When billions upon billions of these cells are stimulated simultaneously, the flash is bright enough to silhouette surfers on the waves at night.”

While most people saw a blue light, some reported it to be greenish, Dr. Franks said.

“The bioluminescence is thought to be a predator deterrent,” Dr. Franks said. “This could work in two ways. First, the predator might not like eating food that flashes in its mouth. Second, another predator might see the first predator all lit up and come over to eat that predator.”

Red Tide update....

10.21.11 report, sorry everyone running a bit behind, but catching up rapidly. In our area we're still in the clear thank goodness!

Southwest CoastThe Karenia brevis bloom first reported three weeks ago in southwest Florida, currently extends alongshore of southern Sarasota County south to Lee County.  Medium concentrations of K. brevishave been reported alongshore of Charlotte County with very low to low concentrations reported alongshore of southern Sarasota County. Analysis of water samples also confirmed the presence ofK. brevis in Pine Island Sound (Lee County).  Although weather prevented offshore sampling by FWRI and other researchers, measurements from two autonomous underwater vehicles (AUV’s) deployed by Mote Marine Laboratory and USF’s College of Marine Science, found a patchy bloom between 10 and 50 km offshore of Charlotte and Lee counties. 

Karenia brevis was not detected in water samples collected this week alongshore of Pinellas, Hillsborough, Manatee and Collier counties.       

Bloom Boundary

This week, Karenia brevis abundance was greatest alongshore of Charlotte County. Widespread fish kills have been associated with this bloom and respiratory irritation is possible in and around the bloom areas.

Northwest Coast

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

East Coast

Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week in the Indian River Lagoon (Brevard County). An ongoing microflagellate bloom continues in this area (first reported on 05/13/2011). 

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.

Red Tide.... it's back

A previous Red Tide Bloom

The Karenia brevis bloom reported last week alongshore of central Sarasota County was documented yesterday outside of Charlotte Harbor via satellite images.  This southward movement is consistent with model predictions reported by the USF’s College of Marine Science Center for Prediction of Red Tides. Analysis of water samples confirmed the presence of K. brevis ranging from very low to low concentrations alongshore between southern Sarasota County and northern Lee County.

 

On the northwest coast of Florida, Karenia brevis was not detected in a water sample collected alongshore of Walton County.

 

No samples have been received so far this week from the east coast of Florida.

Red Tide, Karenia brevis Sept 27th report

Data provided by Mote Marine Laboratory from samples collected by the Sarasota Health Department showed medium concentrations of Karenia brevis, the Florida Red Tide organism, in one water sample taken from Manasota Beach, and low concentrations in water samples collected near Venice Beach and Englewood.  In response to these observations, additional sampling is scheduled for this week.  Karenia brevis was not detected in a water sample received offshore of Lee County.

On the northwest coast of Florida, Karenia brevis was not detected in a water sample collected offshore of Okaloosa County.

No samples have been received so far this week from the east coast of Florida.

Sampling will continue this week, and complete results will be available in the next scheduled status report on Friday, September 30.

Red Tide Karenia Brevis update

East Coast

Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week in the Indian River Lagoon System (Brevard County) or offshore of Palm Beach County.

 

Discolored water that has been reported in the Indian and Banana Rivers (Brevard County) for more than four months (first reported 05/13/2011) is from an ongoing bloom of a non-toxic alga.  Fish kills have recently co-occurred with this on-going algal bloom. 

 

Northwest Coast

Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Levy County or offshore of Dixie County.

 

Southwest Coast

Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Pinellas, Hillsborough, Manatee, Sarasota, Lee and Collier counties or alongshore and offshore of the Florida Keys (Monroe County). One sample collected alongshore of Charlotte County contained background concentrations of K. brevis.

Red Tide, Karenia brevis September 16th update

East Coast

Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Dade County.

 

Northwest Coast

Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Okaloosa, Walton, Dixie and Levy counties or offshore of Wakulla and Levy counties.

 

Southwest Coast

Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Pinellas, Hillsborough, Manatee and Collier counties or offshore of Lee County and the Florida Keys (Monroe County). Five samples collected alongshore of Sarasota County (out of 75 total samples) and one sample collected alongshore of Lee County each contained background concentrations of K. brevis. One sample collected alongshore of Charlotte County contained very low concentrations of K. brevis.

 

Samples collected alongshore in Tampa Bay showed no presence of the dinoflagellate Pyrodinium bahamense, suggesting a dissipation of the ongoing bloom first reported in mid-July.
