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.

Campi Flegrei 火山区属于世界上最活跃的火山系统。它成为 ICDP 和 IODP 计划中联合两栖科学钻探方法的对象，因为它被认为代表着重大的地质灾害风险，迫切需要更好地了解火山过程、嵌套破火山口的发展以及火山碎屑事件和沉积物。为了准备本次钻探活动的海洋部分，应于 2008 年 1 月进行现场勘察，收集拟议的波佐利和那不勒斯湾 ICDP 和 IODP 钻探地点附近的多道地震数据。在此，我们应意大利项目合作伙伴的要求提议参与本次调查，他们将提供运输时间和主要基础设施。主要贡献将是收集独特的浅水多道地震数据，这将提供非常高的分辨率，在近岸和沿海环境中具有足够的数据穿透力。对收集到的数据进行船上处理将用于优化勘测计划并找到合适的钻井位置。区域地层学以及与近岸和陆地剖面的相关性将通过对所收集数据的后续科学分析得出。该项目的重点是初步解释和数据包的准备，以完成完整的 IODP 钻探建议。
