Ongoing assessment of the evolution of the pilot sites in Sardinia by IAS-CNR

Enen though the planned pilot activites of RAS - Regione Autonoma della Sardegna in the framework of POSBEMED2 project have been concluded, the work on the beautiful pilot sites in Sardinia shows no signs of stopping.

The CNR Consiglio Nazionale delle Ricerche team keeps studying MariErmi beach evolution at Area Marina Protetta "Penisola del Sinis - Isola di Mal di Ventre", collecting core samples. The cores will give us new insights and knowledge on the long- and short-term beach ridge's stratigraphical evolution.

The alternation of whitish relict quartz sediment, with the brownish biogenic carbonate is noticable in the core section photo. These are likely evidence of storms (quartz) and fair weather (carbonate) sedimentation, occurred through time.

To further increase the accuracy of temporal evolution, some Posidonia oceanica fibres found within the cored sections, will be radiocarbon dated. 

On Is Traias beach, at Area Marina Protetta "Capo Carbonara", drone's aerial photogrammetry and GPS surveys is adding further data expanding our knowledge on this beach system.

After exceptional rainy events at the beginning of the winter season, the ephemeral stream to the back of the beach, redistributed large portion of sand and stored banquettes both in the submerged and subaerial beach. The acquired data will likely allow us to quantify the volumes returned to the system.
