Late-Glacial Climate Transition in the Near East

摘要ATM-9423020 Wright，赫伯特E. 标题：近东晚冰期气候转变 该研究项目将主要通过对湖相碳酸盐的稳定同位素研究，重点研究近东晚冰期气候转变的性质和时间。 我们目前对该地区气候变化的理解是基于在太阳能驱动的气候变化的适当模型可用之前进行的花粉研究。 因此，拟议的调查是专门针对重新评估过去的气候变化在近东地区的日照变化以及全球大气环流模式的变化伴随着北方冰盖的撤退。 将从近东鲜为人知的地区的四湖富含碳酸盐沉积物的岩心中，建立晚冰期至全新世水分平衡突变的稳定同位素地层学。 其目的是测试快速变化的一致性沿着气候样带。

Abstract ATM-9423020 Wright, Herbert E. University off Minnesota Title: Late-Glacial Climate Transition in the Near East This research project will focus on the nature and timing of late- glacial climatic transitions in the Near East, primarily by stable- isotope studies of lacustrine carbonates. Our current understanding of climate change in the region is based on pollen studies conducted before adequate models of insolation-driven climatic changes became available. Hence, the proposed investigation is specifically aimed at reevaluating past climate changes in the Near East in terms of changes in insolation as well as the shift in global atmospheric circulation patterns accompanying the retreat of the Northern Hemisphere ice sheets. Stable-isotope stratigraphy of late-glacial to Holocene abrupt changes in moisture-balance will be developed from cores with carbonate-rich sediments from four lakes in little known parts of the Near East. The objective is to test the coherency of rapid change along a climatic transect.
