On Florida’s east coast, offshore Nassau and Volusia counties, an ongoing cold-stunning event has harmed about 120 green sea turtles so far. While that’s far fewer than the hundreds rescued off the Panhandle, it’s the most stressed turtles the state has documented in Northeast Florida, according to the wildlife agency.

It is always rewarding to return sea turtles to the ocean where they belong,” said Adam Kennedy, director of rescue and rehabilitation at the New England Aquarium.
