Turtles were satellite-tagged and raw data were collected using the Argos system. Dataset includes tracking data of different life-stages: i) 17 one-year-aged post-hatchlings of loggerhead sea turtle came from nests laid on the Mediterranean Spanish coast; ii) 4 loggerhead nesting females collected from nesting events occurred on the Spanish Mediterranean coast; iii) 21 juvenile and 2 adult loggerhead sea turtles from fisheries bycatch. Our data contribute to the knowledge about the spatial use of the loggerhead sea turtle in the Mediterranean Sea and could be used in further analysis regarding habitat use and dispersal of this species in the Mediterranean basin.
