One of its objectives is also the follow-up of the impacts of large marine-based infrastructures, such as large ports.

To study an open resident segment of the Atlantic population, satellite tracking data from previous projects were compiled, and 19 additional animals marked, increasing the dataset to 39 turtles, with 14,608 high quality signals. Each year observation transects were performed on at least three islands for estimating the relative density of turtles. To analyze the segment size/age structure as well as the negative impacting factors on the species, data from all recovery centers in the Canaries were compiled and studied (2,836 specimens, 1998-2012). These dataseries are far from being optimal, but constitute the best available information at present. asNeeded Antonio Machado Observatorio Ambiental Granadilla Primary contact director@oag-fundacion.org NA NA NA Antonio Machado owner NA zd_496 2025-07-31T14:18:07-04:00 dataset Machado A. 2024.
