En las aguas de las islas Canarias (este del Atlántico) se pueden observar diferentes especies de tortugas marinas. Una de ellas es la tortuga verde (Chelonia mydas), menos frecuente que la tortuga boba (Caretta caretta), y de la que se dispone de muy poca información.<br><br>La ONG ADS Biodiversidad desarrolla actualmente un proyecto centrado en la tortuga verde y del que forma parte este programa de marcaje con transmisor. Dicho proyecto pretende determinar el origen de estos ejemplares, conocer su distribución en esta zona, qué tipo de hábitats están usando, y si están ligados o no a áreas con alguna figura de protección como, por ejemplo, la red Natura 2000. Además, se identificarán las principales presiones y amenazas a las que están expuestas estas tortugas.

Monitoring the behavior and migration of sea turtles released after being held in captivity for rehabilitation reasons as well as green turtles that were part of a captive breeding program. The goal of this project is conservation and research of the endangered turtle species: Loggerhead sea turtles (Caretta caretta) and Green sea turtles (Chelonia mydas). with the idea to enhance the growth of their population in the Mediterranean sea. Supplemental infomation: Visit STAT's project page for additional information. This dataset is a summarized representation of the telemetry locations aggregated per species per 1-degree cell.

Databases of visual sightings from the IFAW Song of the Whale vessel from 1993 to 2013 were merged into one dataset. Attributes recorded in these databases may differ. Since GPS data would become too huge to effectively visualize online, every 10th record was extracted. All GPS data can be requested. Environmental attributes were recorded less frequently than the GPS data and not all GPS records get environmental attributes attached.
