Abstract

Adult and Juvenile marine turtles traverse the ocean at distances that can exceed thousands of kilometres in-between their feeding grounds and breeding grounds. Although they forage long distances from their natal beach, they still return to breed, sometimes decades later.

Comparatively, little is known regarding turtles that have been released in the areas they were found as otherwise nonviable hatchlings and then returned back into the ocean after being rehabilitated to a survivable size. 

There is an abundance of data regarding nesting turtles, juvenile and adult turtles once they have  returned from their oceanic phase. 

Little data is available regarding juvenile turtles up to the age of 3.5 years old.  Three turtles, one aged 3.5 years and two, aged 2 years and10months were released with satellite trackers. 

Two turtles travelled thousands of kilometres. The other turtle’s tracker unfortunately stopped after 10 days. The data retrieved from this pioneering study has already yielded novel results in relation to marine turtle navigation and relationships with seismic activity.
