15 long sediment cores from Eifel dry maar lakes have been drilled between 2001 and 2004 by the ELSA project. Colour logging provides the basis for an ice-core-tuned stratigraphy, and 14C dates give absolute dates for interstadials. All 15 cores show repeatedly the same lithological features which will be synthesized into a general succession of lithological units (Normalprofil). Combination of lithology and stratigraphy for all 15 cores will give a complete record of all major climatic, environmental and volcanic events in the Eifel during the last glaciation. Geochemical, sedimentological and mineralogical analysis will be used to understand the environmental and climate causes for the event layers. Time series analysis on the succession of event layers and on the logging data will be use to detect those periodicities and related processes that controlled sedimentation patterns in the Eifel region during MIS2-5.

艾尔莎项目在2001年至2004年期间从艾菲尔干玛珥湖钻取了15个长沉积物岩心。颜色测井为冰芯调谐地层学提供了基础，14 C测年给出了间冰柱的绝对测年。所有15个岩心都反复显示出相同的岩性特征，这些特征将被合成为一系列岩性单元（Normalprofil）。所有15个岩心的岩性和地层组合将完整记录艾菲尔在末次冰期期间的所有主要气候，环境和火山事件。地球化学、沉积学和矿物学分析将用于了解事件层的环境和气候原因。事件层的继承和测井数据的时间序列分析将被用来检测这些周期性和相关的过程，控制沉积模式在艾弗尔地区在MIS 2 -5。
