The proposed project aims to unravel the character of abrupt (decadal-to millenial-scale) natural climate changes in the eastern Mediterranean region during the Late Quaternary as recorded in terrestrial ecosystems. This will be achieved by a high-resolution palynological and stable isotope study of a record from Tenaghi Philippon, NE Greece, and subsequent quantitative paleoclimate reconstructions. Time intervals to be studied represent short-term climate variability under different boundary conditions. These are (1) the Early Holocene climate optimum coinciding with Sapropel S1 formation the the eastern Mediterranean (10-6 ky; "modern" conditions); (2) the Last Glacial Maximum (24-16 ky; fully glacial conditions), (3) the mid-Weichselian (60-25 ky; "semiglacial" conditions), (4) the Eemian interglacial maximum coinciding with Sapropel S5 formation in the eastern Mediterranean (130-115 ky; extremely warm period), and (5) the warm period of the Late Saalian coinciding with Sapropel S6 formation in the eastern Mediterranean (175-160 ky; strong monsoonal activity under glacial conditions). The outcome will be the first comprehensive, quantified record of short-term climatic and environmental variability in Late Quaternary terrestrial ecosystems of the eastern Mediterranean region. The first 2 years of the project ... comprise a first coring at Tenaghi Philippon and high-resolution ... studies of the Early Holocene and Last Glacial Maximum intervals. They are also for further coordinating a deeper coring which will yield material from the intervals (3) to (5) to be studied during the next application period...

该拟议项目旨在揭示陆地生态系统记录的晚第四纪期间地中海东部地区突然（十年至千年规模）自然气候变化的特征。这将通过对希腊东北部Tenaghi Philippon记录的高分辨率孢粉学和稳定同位素研究以及随后的定量古气候重建来实现。要研究的时间间隔代表不同边界条件下的短期气候变率。这是：（1）早全新世气候适宜期与地中海东部腐泥S1建造相一致（10-6千公里;“现代”条件）;（2）末次盛冰期（24-16 ky;完全冰川条件），（3）Weichselian中期（60-25 ky;“半冰川”条件），（4）Eemian间冰期最大期与地中海东部的腐泥S5地层一致（130-115 ky;极暖期）;（5）与地中海东部腐泥S6形成相一致的晚萨利亚期暖期（175-160 ky;冰川条件下强烈的季风活动）。其结果将是第一个全面的，量化的记录短期气候和环境变化在晚第四纪陆地生态系统的东地中海地区。项目的前两年…包括在Tenaghi Philippon的第一次取芯和高分辨率...早全新世和末次冰期最大间隔的研究。它们还用于进一步协调更深的取芯，以便在下一个应用期内从层段（3）至（5）中获得待研究的材料。
