Scientists turn to sharks to improve hurricane predictions

Scientists are exploring the possibility of using sharks to enhance hurricane prediction models. University of Delaware researchers are investigating whether sharks can serve as mobile observers, carrying sensors that measure ocean conditions such as temperature, salinity, and depth. These CTD tags, attached to sharks like shortfin mako, blue, smooth hammerhead, and juvenile great white sharks, transmit data to satellites when the animals surface.

The project aims to gather data on the heat content of the top ocean layer, which significantly influences hurricane intensity. Researchers select sharks that are abundant, widely distributed, and easier to access than other marine mammals. The tagging process, similar to a pit crew in an auto race, is carried out under animal care oversight and takes less than five minutes.

If successful, the data collected by sharks could improve hurricane forecasts, providing more reliable information to coastal communities for better preparedness and resilience against powerful storms.
