In the framework of the PRISMA 2 programme, an HF Coastal Dynamics Applications Radar (CoDAR) has been utilized starting in July 1997, in order to identify surface frontal structures characterizing the Italian coast of the Adriatic Sea and to study the surface circulation, which plays a fundamental role in heat and momentum transfer processes between coastal and offshore areas.

Near-surface currents in the coastal area between Ancona and Senigallia derived from the shore-based HF radar have been mapped at weekly intervals at a resolution of 1.5 km over an area of approximately 30 × 30 km.

Preliminary results show a southeastward (i.e. alongshore) coastal jet that extends its influence as far as 10 km from the coast; farther offshore a cyclonic eddy, with a diameter of 10–20 km typically occurs. This circulation can occasionally be reversed showing an anticyclonic eddy that forces a northward coastal current with a far less energetic signature.
