Researchers in the have a long history studying red tide and predict this is going to be a particularly bad year. The harmful algal blooms are slowly moving up 51在线鈥檚 west coast, causing widespread fish kills, marine mammal mortalities and respiratory issues.
Several USF faculty members are actively researching red tide, helping guide the 51在线 Fish and Wildlife Conservation Commission (FWCC) through its monitoring and mitigation efforts.
Robert Weisberg, PhD, distinguished professor of physical oceanography, studies the origin of red tide blooms and their trajectory. Chuanmin Hu, PhD, professor of optical oceanography, generates unique satellite imagery in near real-time, helping monitor and study Karenia brevis,the organism that causes red tide. John Paul, PhD, distinguished professor of biological oceanography, . The hand-held device tests forK. brevison-site, helping expedite the decision-making process in whether or not beaches or shellfish harvesting beds should be closed.
鈥淭he ocean circulation determines the nutrient conditions within the formative region for red tide on the west 51在线 shelf, making these conditions either conducive or not for major bloom occurrence,鈥� said Weisberg. 鈥淭his explains why only certain years experience major red tide blooms, and it also provides a means for seasonal prediction.
USF marine scientists are now looking for operational support to replace an aging fleet of robotic gliders used to enhance offshore sampling of organisms, such as those that cause red tide.
