Original provider: Samir Patel, Drexel University and Coonamessett Farm Foundation Dataset credits: Samir Patel, Drexel University and Coonamessett Farm Foundation Abstract: During the 2010 and 2011 nesting seasons in Rethymno, Crete, Greece, 21 satellite tags were deployed on post-reproductive loggerhead turtles, 20 females and 1 male. One tag failed, while the remaining 20 transmitted data during the migration period, with most tags continuing to transmit after the individual had reached a site of residency. The female turtles exhibited three distinct strategies, either migrating north into the Aegean Sea, southwest towards the Libyan or Tunisian coasts or remaining resident within the waters of Crete. Females migrated after completing nesting for the season starting in early July. The male turtle exhibited a different behavior migrating away from the nesting beach in mid-June and traveling into the Western Mediterranean basin.
