Tracking sea turtles as they swim for their lives
from The New York Times
When loggerhead turtles hatch on the beach of Boavista, the easternmost of the Cape Verde islands, they head for the water to begin what biologists call a swimming frenzy. The beach and coastal waters are full of predators, and the babies are tasty, nutritious and defenseless. They need to reach ocean currents as quickly as they can, to be carried to less dangerous waters. This is the pattern of baby sea turtles in general, and scientists have had a good idea of what currents they ride. But they haven’t had a reliable way to track the turtles’ swims and see exactly how they manage their first hours.
