该项目将验证全新世期间北大西洋千年变冷事件是由热带经向热输送减少引起的假设。本文将以250年为间隔,对巴哈马和巴西边缘跨越温跃层深度(400-1000 m)的高累积速率沉积物岩心进行底栖动物和浮游有孔虫的C和O同位素组成分析,重点分析底栖动物的18o数据。这些地点的高纬度地表水冷却和低纬度温跃层变暖之间的时间相关性将支持这一假设。
英文摘要
This ESH project will test the hypothesis that millenial cooling events in the North Atlantic during the Holocene are caused by reduced meridional heat transport from the tropics. High0accumulation-rate sediment cores from the Bahamas and the Brazil margin spanning thermocline depths (400-1000 m) will be analyzed at 250-year intervals for C and O isotopic composition of benthic and planktic foraminifera, with emphasis on the benthic 18 O data. A temporal correlation between high-latitude, surface water cooling and low-latitude, thermocline warming at these sites will support the hypothesis.
