Pre-site survey of the marine Campi Flegrei Caldera and the volcanoclastic and sedimentary deposits in the Bay of Naples

坎皮·弗莱格雷火山区属于世界上最活跃的火山系统。在ICDP和IODP计划中，由于认为这是一种重大的地质灾害风险，迫切需要更好地了解火山过程、嵌套破火山口的发育以及火山碎屑事件和沉积，因此必须采取联合两栖方法进行科学钻探。为准备这次钻探活动的海洋部分，将于2008年1月进行现场前勘测，以收集波佐利和那不勒斯海湾拟建的ICDP和IODP钻探地点附近的多道地震数据。在此，我们建议应意大利项目合作伙伴的要求参与此次调查，他们将提供装船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，充分渗透近岸和沿海环境中的数据。对收集的数据进行船上处理将用于优化测量计划和确定合适的钻探位置。区域地层学以及与近岸和陆地剖面的对比将由随后对收集的数据进行科学分析而得出。该项目的重点将是初步解释和编制数据包，以完成IODP钻探的完整提案。

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.
