该奖项是对一项研究的支持,该研究旨在利用北美东部已知和估计的现在和过去气候变量模式,将选定生物标志物的Dd(重氢)值发展为气候测量的新替代指标。该项目将研究北美东部和尤卡坦半岛七个研究充分的沉积物地点的湖泊表层沉积物和沉积物岩心中单个生物标志物的氢同位素组成如何变化。调查人员还将收集和分析沿表层沉积物站点横断面的湖水和水生植物的DD值。
英文摘要
This award is for support of a study to take advantage of the known and estimated patterns of present and past climate variables in eastern North America in developing dD (deuterium) values for selected biomarkers into a new proxy for climate measurements. The project will study how the hydrogen isotopic composition of individual biomarkers varies in lacustrine surface sediments and in sediment cores from seven well-studied sediment sites in eastern North America and Yucatan Peninsula. The investigators will also collect and analyze dD values of lake water and aquatic plants along transects of surface sediment sites.
