Monitoring Database

Florida's HAB historical database is one of the largest and longest continually recorded electronic HAB databases in the United States. Articles in this section explain how red tide data collection has evolved over the years and how to interpret the data accurately. Also presented is a table showing that red tides have occurred off the west coast of Florida for more than 160 years.


The HAB monitoring database was created to consolidate historical and current Florida red tide sampling information. Data recorded in the database includes sample location, organism counts, water quality measurements, and other related data.
