Instead of watching…
Subsea fibre-optic cables. Image Credit: AI Generated Fibre-optic cables spread across the seafloor have long carried internet traffic between countries, but researchers are discovering another surprising use for this global network; detecting whales. A 2022 study in ‘Frontiers in Marine Science’ showed that existing submarine fibre-optic cables could be turned into vast underwater sensors capable…
Florida’s Everglades is facing a stealthy invasive threat beneath its waters as the Asian swamp eel spreads through wetlands and preys on fish, crayfish, frogs and other aquatic animals.
