- The Karenia brevis status for locations across Sarasota and Manatee counties as listed in the map from the Florida Fish & Wildlife Conservation Commission. Per the FWC-FWRI: "These data represent the most recent eight (8) days of sampling location points for Karenia brevis, the phytoplankton that causes red tide, in Florida. These data are exported daily at 4:45 PM Eastern Time from the Florida Fish and Wildlife Conservation Commission-Fish and Wildlife Research Institute Harmful Algal Bloom Database, which provides information on the presence (as a categorical abundance) and absence of Karenia brevis."
- The aerosol and fish kill status data are from Sarasota County red tide dashboard, which also includes county cleanup information and is updated at 11:30 a.m. daily.
