This project provide sparse acoustic coverage to the whole Ria de Vigo (Galicia, Spain) and was originally deployed to investigate the movement ecology and behavioural variation of mutliple species of skates, rays and sharks in the Ria. The telemetry array was deployed using multiple mooring and attachment systems. It divides the Ria in three sectors and it provides additional coverage to the northern and southern coasts and some coverage also to the deeper central areas of the Ria. The initial deployment took place in 2024 and it was mainly funded by project BELAS (Spanish Research Agency) but also by project CORME (Xunta de Galicia).
