中文摘要
9709686基格温这项研究将通过收集和分析百慕大隆起、劳伦斯扇、卡罗莱纳州大陆斜坡和大西洋中部海湾的沉积岩芯,来表征北大西洋西部的全新世变异性。化探、沉积学和微化石分析将被用来检验(1)北大西洋深水的低组分在小冰期期间是否减少,以及(2)小冰期和中世纪暖期等变暖和降温时期是否在中纬度西大西洋普遍存在。该项目由美国全球变化研究计划的地球系统历史部分资助。
英文摘要
9709686 Keigwin This study will characterize Holocene variability in the western North Atlantic by collection and analysis of sediment cores from the Bermuda Rise, Laurentian Fan, and continental slopes of the Carolinas and the mid-Atlantic Bight. Geochemical, sedimentological and microfossil analysis will be used to test whether (1) production of the lower component of North Atlantic Deep Water diminished during the Little Ice Age and (2) warming and cooling intervals such as the Little Ice Age and the Medieval Warm period were widespread in the mid-latitude western Atlantic. The project is funded under the Earth System History component of the US GLOBAL Change Research Program.
