RESULTS

Fig.9 shows the pattern of lines acquired during the multibeam runs. Fig.10 presents shaded relief maps of the multibeam data, gridded at 250 m (Tyrrhenian Sea) and 100 m intervals (Ionian Sea).

The multibeam data were edited and processed on-board, at the scales of 1:100000, 1:250000, 1:500000. The data quality ranged from good to acceptable.

Magnetic recordings showed a good continuity and quality of data, requiring just a minimal pass for filtering prior of the IGRF-95 anomaly calculation.

Continuous Seismic profiling was done for almost the totality of the cruise, giving the chance to define the thickness of the sediments above the acoustic basament and the structural makeup of the area.

Gravimetry data were collected during the whole cruise, and processing is ongoing to calculate free air and Bouguer anomalies.
