Endangered sea turtles hear ship noise loud and clear

Kemp's ridley sea turtles rank among the most endangered sea turtle species on the planet. They live along the East Coast and Gulf Coast of North America, sharing these waters with some of the busiest shipping routes in the world. Scientists already know that fishing gear, pollution, and ship strikes threaten their survival. What remains less certain is how much human-made noise affects these turtles as they move through such crowded environments.
