Interannual-to-Millennial-Scale Environmental Variability asRecorded in Laminated Sediments of the Cariaco Basin, Venezuela

利用1990年在(委内瑞拉)Cariaco盆地收集的岩心，拟议的分析将侧重于过去2-3万年来上升流的年际和千年尺度变化、区域风力强度以及南美洲北部的水文平衡。特别令人感兴趣的将是关于小冰河时代和年轻的仙女座事件的十年记录。VARVE年表和14-C年表的比较将提供最后一次冰川消融期间14-C长期变化的迫切需要的独立记录。

Using cores collected in the Cariaco Basin (Venezuela) in 1990, proposed analyses will focus on interannual and millennial-scale variability in upwelling, regional wind strength, and the hydrological balance in northern South America\ over the last 20-30 thousand years. Of particular interest will be decadal records over the Little Ice Age and the Younger Dryas Event. Comparison of varve and 14-C chronologies will provide the much-needed independent record of e\secular 14-C variations through the last deglaciation.
