Preliminary results of the ocenographic cruise CAFEO7_Leg 3 in the bays of Napoli and Pozzuoli, Eastern Tyrrhenian Sea

We present the preliminary results of the oceanographic cruise CAFE_07 - Leg 3, conducted in the Napoli and Pozzuoli Bays in January 2008, on board of the Research Vessel (R/V) URANIA of the CNR. The aim of the cruise was the acquisition of high resolution multi-channel seismic profiles to understand the stratigraphic-structural setting of the Pozzuoli Bay area, with specific reference to the major offshore volcanic features, as well as the acquisition of bathymetric data on the seafloor morphology of the Bay. About 800 km of seismic profiles were acquired simultaneously by two acquisition systems, each characterized by different seismic source and streamer configuration, operating at different frequency ranges. Moreover shallow high resolution seismic reflection profiles (sub-bottom CHIRP) and multibeam echo-sounder bathymetry data have been recorded. The seismic grid consisted in a number of assistant profiles acquired over the Bay of Naples, along with a dense network of profiles with average distance of about 150 m between navigation routes, in order to obtain a quasi 3-D seismic coverage of the Pozzuoli Bay. This data set represents a part of the requirements for on-site detailed investigations ("site survey") that are necessary for the development of an Integrated Ocean Drilling Program (IODP) proposal dedicated to the offshore drilling of the Campi Flegrei and is a relevant complement in the site survey of an ongoing project that has been submitted to the International Continental Drilling Program (ICDP).
