Unprecedented Year-Long Tracking of Juvenile Loggerhead Turtles Thanks to Microsatellite Tags
In July 2024, researchers released ten rehabilitated juvenile loggerheads into the Bay of Biscay, equipped with miniaturized satellite tags to track their movements. One turtle was tracked for longer than a full year, setting a record for turtles of its size. Led by Upwell, Aquarium La Rochelle, and Mercator Ocean International, the project is revealing […]
