Sharks will predict hurricanes now

DELAWARE: University of Delaware scientists are equipping wild sharks along the U.S. East Coast with specialized electronic tags to significantly improve hurricane forecasting accuracy.

Why Sharks Could Help Predict Hurricanes?

Because tropical storms draw immense power from subsurface heat, ocean surface satellites often fail to capture critical thermal layers.

As tagged sharks dive deep into these hard-to-reach marine environments, their non-invasive sensors continuously record underwater temperature, salinity, and depth.

Beginning every spring, research crews deploy 30 to 40 miles offshore to tag species like mako and hammerhead sharks. The electronic devices are secured to dorsal fins in under five minutes to minimize stress, utilizing temporary materials designed to naturally corrode and drop off later.

Each time a shark breaks the surface, gathered environmental metrics automatically stream to orbiting satellite networks. Feeding this real-time data directly into atmospheric models enables meteorologists to track rapid storm intensification and deliver earlier, life-saving warnings to coastal communities.
