IFREMER/Kélonia satellite tracked late juvenile loggerhead sea turtles from Réunion Island 2008-2012 Citation Contact: Bourjea, Jérôme ; Dalleau, Mayeul Availability:  This dataset is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License.Notes: Only data aggregated per 1-degree cell are available through OBIS. The non-aggregated data are available through the OBIS-SEAMAP Portal Description Satellite data from tracking study conducted on juvenile loggerhead sea turtles in the Indian Ocean. more Eighteen individuals were fitted with transponders and tracked from Réunion Island (21.2°S, 55.3°E) in order to investigate movements and diving patterns. Nine turtles swam north towards Oman (20.5°N, 58.8°E), where one of the world’s largest rookeries of loggerheads is located. Three individuals travelled south towards South-Africa and Madagascar, countries that also host loggerhead nesting grounds. Fourteen of the transmitters relayed diving profiles. A dichotomy between diurnal and nocturnal diving behavior was observed. A greater number of shorter dives occurred during the day. Diving behavior also differed according to movement behavior as individuals spent more time in subsurface waters (<10 m) during transit phases. The study provides an improved understanding of the oceanic movements and diving behavior of juvenile loggerheads. The results address a significant gap in the understanding of loggerhead oceanic movements and may help with the conservation of the species.
