Some Red Tide Characteristics During 1952–1954
Survey counts of Gymnodinium brevis, miscellaneous chemical analyses (Kjeldahl nitrogen, total phosphorus, total organic matter, chlorophyll, and nitrate), and a few light intensity and productivity measurements in Florida's red tide zone from 1952 to 1954 indicated a widespread general regime of this dinoflagellate growing sparsely in heterogeneous poor to moderately fertile water with a high N/P ratio. Occasional bloom patches and fish kills were accompanied by somewhat higher nutrient levels. The fertile estuaries, Tampa Bay and Charlotte Harbor, in contrast to the Caloosahatchee River are capable of stimulating coastal fertility with injections of nitrogen and phosphorus. Offshore mixing of high N/P ratio water of the Caloosahatchee estuary and the low N/P ratio water of Tampa Bay and Charlotte Harbor may produce a wide range of nutrient conditions. A decrease in estuarine pollution is suggested as a remedial experiment.
