The final goals of this project are: 1) To establish a seismo-stratigraphic framework for Late- Quaternary carbonate deposits in the almost siliciclastic free settings at the Alboran Ridge, Oran Bay, and south-western Mallorca. 2) To reconstruct the prevailing and ancient oceanographic setting on the basis of drift deposits in all working areas. 3) To investigate gas traps in Late-Miocene carbonates and migration paths into the Pliocene-Quaternary overburden south-west of Mallorca. 4) To analyze neotectonic activity off Bolonia Bay, north and south of the Alboran Ridge, and off Oran in order to unravel its impact on the sedimentary succession in terms of fault pattern and mass wasting. This will be achieved by means of seismic and hydroacoustic data Interpretation collected during the cruise M69/1 (Western Mediterranean Sea) in September 2006. The seismic data have been recorded by a highly sophisticated 144-channel digital streamer System. During the first period the working program aims on the processing and Interpretation. Advanced processing methods like CRS-stacking, NIP-tomography and pre-stack depth migration will be applied in order to optimize the imaging. The Interpretation will be carried out in 2D and 3D.

该项目的最终目标是：1)为阿尔博兰海脊、奥兰湾和马略卡岛西南部几乎没有硅质碎屑环境的晚第四纪碳酸盐矿床建立地震地层格架。2)在所有工作区漂流沉积的基础上重建当时和古代的海洋环境。3)研究马略卡岛西南地区晚中新世碳酸盐岩中的天然气圈闭和进入上新世-第四纪盖层的运移路径。4)分析博洛尼亚海湾、阿尔博兰海脊南北、奥兰近海的新构造活动，从断层形态和物质损耗的角度揭示其对沉积序列的影响。这将通过2006年9月在M69/1号游轮(西地中海)期间收集的地震和水声数据解释来实现。地震数据是由高度复杂的144通道数字流光系统记录的。在第一阶段，工作方案的目标是处理和解释。将采用CRS叠加、NIP层析成像和叠前深度偏移等先进处理方法，以优化成像。解释将以2D和3D进行。
