The Gulf water temperature is at its highest, conducive for tropical storm development. Researchers at the University of Miami have joined forces to achieve dual goals. Atmospheric scientists and marine biologists are predicting the severity of tropical storms and evaluating fish migration. Since 2001, one team has been tagging large pelagic fish such as tarpon, with satellite linked sensors that measure ocean temperature, depth, light level and salinity. Sharks have also been tagged for the last four years as researchers noticed they follow a line of water that is 79 degrees F, a reading that is also the lower-bound temperature for tropical storms. Data is transmitted in real time and fish in a storm area will assist in predicting storms.
