Introduction

The Campi Flegrei Volcanic District belongs to the most active volcanic systems in the world. It became subject to a joint amphibic approach for scientific drilling in the ICDP and IODP programs, as it is assumed to represent a significant geohazard risk, which urgently needs a better understanding of the volcanic processes, the development of nested calderas and the volcanoclastic events and deposits.

For preparation of the marine portion of this drilling campaign, a pre-site survey shall be carried out in January 2008 to collect multichannel seismic data in the vicinity of the proposed ICDP and IODP drill sites in Pozzuoli and Naples Bay. 

Here we propose a participation in this survey on request of Italian project partners, who will provide ship time and major infrastructure. The main contribution will be the collection of unique shallow water multichannel seismic data, which will provide a very high resolution, a sufficient penetration of data in nearshore and coastal environments. Onboard processing of the collected data will be used to optimize the survey plan and to locate suitable drilling locations. Regional stratigraphies and correlation with nearshore and terrestrial section will result from the subsequent scientific analysis of the collected data. The focus within this project will be on a preliminary interpretation and a preparation of a data package to complete a full IODP drilling proposal.
