As shown here the turtles generally remain in a narrow temperature band and move north and south seasonally with that temperature band. "Contrary to expectations, our analysis shows that even the youngest turtles can influence their migratory path enough to affect the likelihood of survival," Lohmann said. Most of the turtles made the same steering decisions that wild turtles make as they follow their circular route around the Atlantic.
