Bündelantrag SCOPSCO: Scientific Collaboration on Past Speciation Conditions in Lake Ohrid - Correlation of Seismic Records with Physical Property and Sedimentological Data

阿尔巴尼亚和马其顿之间的跨界奥赫里德湖被认为是欧洲最古老的持续存在的湖泊，年龄可能为300万至500万年。一个非常高的地方性，包括210多个描述的特有物种，使湖泊成为一个独特的水生生态系统的世界性的重要性。ICDP钻探活动计划于2011年春季进行，以获得有关以下方面的可靠信息：（1）奥赫里德湖的年龄和起源;（2）整个第四纪期间主要的地质、环境和气候变化;以及（3）生物进化的驱动力。根据2007年和2008年现场前调查期间收集的高分辨率地震数据，提出了五个主要地点。该提案的主要目的是对钻井和地震数据进行综合解释，以重建奥赫里德湖的成因和演变。将计算合成地震图，以便将地震和钻井数据相关联。密集测井程序（岩心和井下测井）将是这种方法的基础。测井和地震数据的集成允许通过使用地震数据将地层从威尔斯外推到3D空间。特别强调将提请广泛的质量浪费事件的时间，这可能是用来作为代理估计古地震活动，在湖平面的波动，这发挥了重要作用的奥赫里德湖的沉积演化，火山灰分布，这可能是生物进化的驱动力之一。

Transboundary Lake Ohrid between Albania and Macedonia is considered to be the oldest continuously existing lake in Europe with an age of likely three to five million years. An extraordinary high degree of endemism, including more than 210 described endemic species, makes the lake a unique aquatic ecosystem of worldwide importance. An ICDP drilling campaign is scheduled for spring 2011 in order to obtain robust information (1) about the age and origin of Lake Ohrid, (2) about major geological, environmental and climatic changes during the entire Quaternary, and (3) about the driving forces for the biotic evolution. Five primary sites are proposed based on high resolution seismic data collected during pre-site surveys in 2007 and 2008. The main aim of this proposal is an integrated interpretation of the drilling and seismic data in order to reconstruct the genesis and evolution of Lake Ohrid. Synthetic seismograms will be calculated for a correlation of seismic and drill data. An intensive logging program (core and downhole logging) will be the basis for this approach. The integration of logging and seismic data allows extrapolating the stratigraphy from the wells to 3D-space by using the seismic data. Special emphasis will be drawn on timing of widespread mass wasting events, which might be used as proxy for estimating the paleoseismicity, on lake-level fluctuations, which played an important role for the sedimentary evolution of Lake Ohrid, and on the tephra distribution, which might be one driving force for the biotic evolution.
