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.

Historical-DatabaseFlorida has one of the largest and longest continually recorded electronic HAB databases in the United States. Florida red tide data collected since 1953 by government and private sources were originally stored as hardcopy datasheets and in separate electronic files. In 1999, FWRI scientists recognized the need to consolidate existing statewide red tide sampling information into a single electronic format and developed a relational HAB database designed to capture core historical data and related sampling information. Data transferred to the database include location coordinates, cell counts of Karenia brevis (the Florida red tide organism) and other HAB species, and a broad selection of oceanographic and water quality measurements such as temperature, salinity, and dissolved oxygen. The database is continually updated with current information as data are received. Database managers routinely analyze the database and provide results to FWC scientists and other researchers.



FWC Facts:
Red tides are not always red. They can appear green, brown or even purple in color. The water can even remain its normal color during a bloom.
