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.

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.

Several species of sea turtles can be observed in waters off the Canary Islands (Eastern Atlantic). One of them is the green turtle (Chelonia mydas), less frequent than the loggerhead sea turtle (Caretta caretta), and with little information.<br><br>The NGO ADS Biodiversidad is currently developing a project based on the green turtle and this satellite tracking programme forms part of it. The aims of this project are to determine the origin of these individuals, know their distribution in this area, determine the habitats that they are using and define if they are linked or not to protected areas (e.g. Natura 2000 network). Furthermore, the main pressures and threats that are affecting to this species will be determined.<br><br>Results of this project will be disclosed among the local population, that poorly know the presence of the species in Canarian waters, even for some professionals that interact directly with them (e.g. fishermen and divers).
