Red Tide Overview

This article, written by Florida Sea Grant Extension Agent Betty Staugler, gives an overview of red tides in Florida — what their causes and impacts are, and where to find additional information.

The Basics of Florida Red Tides

Harmful Algal Bloom State of the Science Symposium

UPDATE: A consensus document from the 2019 Harmful Algal Bloom State of the Science Symposium was published in February 2020. A pdf of the document can be downloaded here:

State of the Science for Harmful Algal Blooms in Florida: Karenia brevis and Microcystis spp.

In August 2019, Florida Sea Grant and University of Florida’s Institute of Food and Agricultural Sciences convened a meeting of more than 70 HABs experts at the U.S. Geological Survey offices in St. Petersburg to discuss the state of research on HABs in Florida.

The UF/IFAS Florida Sea Grant Harmful Algal Bloom State of the Science Symposium brought together researchers from around the state and across the country to discuss what is known about HABs, especially Karenia brevis red tide and Microcystis aeruginosa cyanobacteria — two main HABs impacting the state. The group was tasked with assessing the current state of the science and prioritizing research needs in the areas of:

• Initiation, development and termination of blooms
• Prediction and modeling
• Detection and monitoring
• Mitigation and control
• Public health

HAB Liaison Position

Betty Staugler, Florida Sea Grant extension agent based in Charlotte County, was recently named Florida Sea Grant HAB liaison to National Oceanic and Atmospheric Administration’s National Centers for Coastal Ocean Science (NCCOS). The lab forecasts and models harmful algal blooms occurring in Florida and the Southeast. Betty will work with NCCOS researchers to create and distribute data, tools, and outreach materials to groups and individuals working to help Florida prepare for and weather blooms.
