In addition to occurring along the Gulf coast, a minor and short-lived G. breve bloom was observed during September and October in the Atlantic along the northeast Florida coast between Cape Canveral and the Georgia state line. The G. breve cell count data page provides maps of the affected areas and a description of the intensities of the blooms. A second bloom began in the Florida Panhandle during November and persisted until the end of December. Little or no incidence of G. breve was observed in this region during January. As of the beginning of February the situation has returned to normal conditions and sampling has ceased.
Numbers refer to the number of sites sampled.
Along the southwest coast a different pattern of G. breve blooms has occurred. An initial fall bloom occurred in September and October followed by a second bloom beginning in late December. This second bloom has persisted and moved southward through the month of February. In late January fish kills were reported near Key West. Low to medium concentrations of G. breve in the westernmost Florida Keys have been detected in early February.
