GRAVIMETRY, MAGNETOMETRY AND BATHYMETRY

During PANSTR10 cruise, high-resolution gravimetric, magnetometric and morpho-bathymetric surveys were made principally on N-S tracks spaced 500 m , in the area of Panarea an Stromboli volcanoes an surroundings. Close to the islands detailed coverage of multibeam acquisitions were done, and around the Panarea submerged volcano data were acquired along N-S tracks spaced 250 m.

In particular, magnetic acquisitions were controlled for every runlines, by plotting preliminary results on a 180 m equispaced grid, to check goodness of results. Figures 6 and 7 show profiles obtained by sampling this grid, to verify the coverage of the data.

Multibeam swath bathymetry have been acquired along the magnetic and gravimetric runlines as well.

OBS

Four INGV designed OBS were deployed on the lineament Stromboli-Marsili; one of these was deployed on top on the Marsili Smt., to monitor also the seismic and volcanic activity. The other OBS was deployed N of the Alicudi I., aiming at obtaining earthquake data for improving quality of focal solutions in the Western Eolian Sector. All the five OBS were also deployed for the MEDOC seismic shooting operations (120 L, 90 s interval), that occured April-May 2010 with the spanish R/V Sarmiento de Gamboa (Ranero, Zitellini et al., cruise report in preparation).

During shooting of E-W transect Sardinia to Italy at 40N , the INGV stations located in Lipari, Ustica and Alicudi and were able to receive signals, therefore we may be confident that the OBS's were illuminated as well by the shots (Figs. A5, A6 and A7 in the Appendix C).

Among the others OBS A7 (Fig. A4 was dropped on the depression ($\sim$ 785-790 m) just SSW of the summit of the Marsili Smt., $\sim$ 60 m to the NNE of the deployment of the MRS06 cruise also MRS06-REP).
