The turtles tracked in this project are of the first loggerheads to be tracked during their postnesting migration from a Greek nesting beach. The project is carried out by the division of Conservation Biology of the University of Berne (Switzerland) in collaboration with ARCHELON, the Sea Turtle Protection Society of Greece. Zakynthos is the largest known sea turtle nesting area of the Mediterranean, hosting about 1/4 of all known loggerhead nesting in the Mediterranean. The nesting beaches of Zakynthos are monitored by ARCHELON since 1983.
