Background – we put satellite tags on 3 turtles in Bermuda this July/August as part of a study of home range and habitat utilization on the Bermuda platform. We expected these turtles to show the same behaviors as other tagged turtles on Bermuda – that is, to stay within about 500m of where they were tagged for years. But, we managed to pick two turtles that had finished their growing up in Bermuda and left the platform, on their way to mating grounds (we think in Nicaragua, but we’ll see). The satellite tags give 2 kinds of position data – relatively imprecise Argos satellite locations similar to old fashioned LORAN, and GPS. The only other data on where the turtles go after leaving Bermuda to date came from a flipper tag from a Bermuda turtle collected from a fisherman in Nicaragua. An NGO also tagged two additional turtles – look at the public education web site “Tour de Turtles” http://www.tourdeturtles.org/Bermuda/ to get some more background. This web page was intended as a lesson in geography and conservation biology for Bermuda school kids.
