Current Conditions
Over the past week, the red tide organism Karenia brevis was detected in 125 samples collected from Northwest and Southwest Florida. Bloom concentrations (>100,000 cells/liter) were observed in 24 samples: one offshore of Pasco County, four offshore of Pinellas County, one from Hillsborough County, five from and offshore of Manatee County, 10 from Sarasota County, two from and offshore of Charlotte County, and one from Lee County. Light microscopy and/or automated shipboard analysis of samples collected between 11/9 to 11/16 confirmed the presence of K. brevis from and/or offshore of Pasco to Monroe counties. Chlorophyll satellite imagery (USF, NOAA) continues to be dynamic, with imagery from 11/19 showing patches of elevated chlorophyll along and/or offshore of Pinellas, Charlotte, and Lee counties.
Additional details are provided below.
In Southwest Florida over the past week, K. brevis was observed at background to medium concentrations in and offshore of Pinellas County, low to medium concentrations in and offshore of Hillsborough County, background to medium concentrations in and offshore of Manatee, Sarasota, Charlotte, and Lee counties, and background to very low concentrations offshore of Collier County.
In Northwest Florida over the past week, K. brevis was observed at medium concentrations in one sample collected offshore of Pasco County.
Along the Florida East Coast over the past week, K. brevis was not observed.

Current Conditions
Over the past week, the red tide organism Karenia brevis was detected in 76 samples collected from Florida’s Gulf Coast. Bloom concentrations (>100,000 cells/liter) were present in 18 samples: 2 offshore of Pinellas County, 3 from and offshore of Sarasota County, 4 offshore of Charlotte County, 8 offshore of Lee County, and 1 offshore of Collier County. Satellite chlorophyll imagery (NOAA, USF) from 10/31 indicates patchy conditions along Southwest Florida, with elevated chlorophyll extending along ~160 miles of coastline. Elevated chlorophyll levels were observed ~25-35 miles offshore of Pasco County, and alongshore from southern Pinellas County to Lee County. The patch ranges from ~5 miles wide to ~20-25 miles wide off of Charlotte Harbor and Tampa Bay estuaries. Additional details are provided below.
• In Southwest Florida over the past week, K. brevis was observed at background to medium concentrations in and offshore of Pinellas County, very low to low concentrations in and offshore of Manatee County, background to high concentrations in and offshore of Sarasota County, background to high concentrations in and offshore of Charlotte County, very low to medium concentrations in and offshore of Lee County, background to medium concentrations offshore of Collier County, and background concentrations offshore of Monroe County.
• In Northwest Florida over the past week, K. brevis was at background concentrations in one sample collected from Franklin County.
• Along the Florida East Coast over the past week, K. brevis was not observed.

WE ARE ALL CONNECTED...
Hurricane Helene has caused dramatic impacts to our communities and to natural resources in the Nature Coast region. Helene caused the highest storm surge ever recorded in Cedar Key, with over 13 feet storm surge (MLLW) recorded at the Cedar Key NOAA gauge. Most folks in our area were spared from storm surge impacts from Hurricane Milton, but the impacts of Helene created huge challenges for many of us. Regarding our facilities at NCBS and the Seahorse Key facilities we help manage, all received damage, which has been summarized on our social media and I won’t go into detail here.
The outpouring of volunteers to our communities has made a huge impact on the initial recovery from this storm, and without those volunteers, we would be substantially delayed in any recovery efforts. We are all grateful for the folks who have taken their time to come to help, often from long distances and much personal expense.
Every hurricane we have faced has created lessons about how to prepare for storms, but in my view the biggest lesson from Helene is that we are literally all connected. In ecosystem science the concept of connectivity is pervasive, where loss of one part of the system influences the rest of the food web. If you lose seagrass habitat, you functionally change the rest of the food web, all the way up to humans. Similarly, damage to oyster reefs, mangroves, and salt marsh all have cascading impacts to forage fishes, predators, sea birds, sea turtles and marine mammals.
