The project "Scientific Collaboration on Past Speciation Conditions in Lake Ohrid" (SCOPSCO) established ca. 7 years ago, when a deep drilling full proposal was submitted to the International Continental Scientific Drilling Program (ICDP). Within this proposal, four major aims were defined. These aims are (i) to obtain more precise information about the age and origin of the lake, (ii) to unravel the seismotectonic history of the lake area including effects of major earthquakes and associated mass wasting events, (iii) to obtain a continuous record containing information on volcanic activities and climate changes in the central northern Mediterranean region, and (iv) to better understand the impact of major geological/environmental events on general evolutionary patterns and shaping an extraordinary degree of endemic biodiversity as a matter of global significance. The very successful deep drilling campaign carried out at Lake Ohrid in spring 2013 forms the backbone for answering these aims. During the field campaign, more than 2000 m of sediments were drilled from four different sites in Lake Ohrid. The project applied for here is a renewal proposal and focuses on the main drill site, the DEEP site in the central part of the lake. At this site, overall 1526 m of sediments were recovered from 6 parallel holes with a maximum sediment depth of 569 m below lake floor (blf). As the recovered cores from the individual holes at DEEP site partly overlap, an almost complete composite core can be established, with a recovery of more than 99 % for the uppermost 480 m and a total recovery of more than 95 % for the entire 569 m according to field data. The project here applied for encompasses sedimentological analyses, tephrostratigraphical work, and chronostratigraphical work on the cores from DEEP site, partly in close collaboration with national and international partners, and is addressed to answer the main aims (i), (iii) and (iv) listed above. It will also provide the scientific backbone for all other sedimentological, geochemical and biological/paleontological work on the sediment record carried out by the international scientific community involved into the SCOPSCO project. For the third year of the project, the scientific studies will concentrate on the lower part of the DEEP site sequence, which covers the Mid Pleistocene transition and the period > 1 million years.Preliminary field data and first scientific results indicate that the composite core from the DEEP site spans with a decadal resolution between 1.2 and 1.9 Ma. With the proposal applied for here, the Lake Ohrid record will become a key record for paleoenvironmental changes in the Mediterranean region and for the activity of Italian volcanoes and will allow a unique insight into the mechanisms of speciation and evolution of taxa.

该项目“科学合作过去的物种形成条件在奥赫里德湖”（SCOPSCO）成立约。7年前，向国际大陆科学钻探计划（ICDP）提交了一份深钻完整建议书。在这一建议中，确定了四个主要目标。这些目标是：（一）获得关于湖泊年龄和起源的更精确的信息;（二）揭示湖区的地震构造历史，包括大地震和相关质量损耗事件的影响;（三）获得包含地中海北方中部地区火山活动和气候变化信息的连续记录;以及（iv）更好地了解重大地质/环境事件对一般进化模式的影响，并将形成具有全球意义的地方性生物多样性的特殊程度。2013年春季在奥赫里德湖进行的非常成功的深层钻探活动构成了实现这些目标的支柱。在实地活动期间，从奥赫里德湖的四个不同地点钻取了2000多米的沉积物。这里申请的项目是一个更新的建议，重点是主要的钻井现场，在湖的中心部分的深水现场。在该站点，从6个平行孔中回收了总计1526 m的沉积物，最大沉积物深度为湖底（blf）以下569 m。由于从DEEP现场的各个钻孔中回收的岩心部分重叠，因此可以建立几乎完整的复合岩心，根据现场数据，最高480 m的回收率超过99%，整个569 m的总回收率超过95%。本申请项目包括沉积学分析、火山灰地层学工作以及对深海钻探站岩芯的年代地层学工作，部分工作是与国家和国际伙伴密切合作进行的，旨在实现上述主要目标（一）、（三）和（四）。它还将为参与SCOPSCO项目的国际科学界就沉积物记录开展的所有其他沉积学、地球化学和生物/古生物学工作提供科学基础。在项目的第三年，科学研究将集中在DEEP站点序列的下部，其中包括中更新世过渡期和100万年以上的时期，初步现场数据和第一批科学结果表明，DEEP站点的复合岩心的十年分辨率在1.2和1.9 Ma之间。随着这里申请的建议，奥赫里德湖记录将成为地中海地区古环境变化和意大利火山活动的关键记录，并将使独特的洞察机制的物种形成和进化的类群。
