中文摘要
该奖项是对新罕布夏州怀特山脉3个湖泊的岩心进行高分辨率、多代理分析。古环境重建将以下列替代记录为基础:(1)沉积物岩性和有机质百分比--侵蚀速率和陆地和水生生产力;(2)摇蚊--夏季最高水温;(3)花粉和植物大型化石(气孔、针叶和种子)--植被和物种范围界限的变化。这项研究的目的是确定在北大西洋观察到的寒冷事件和千年尺度的气候变异性是否影响了新汉普郡怀特山的环境。。
英文摘要
This award is for high-resolution, multiproxy analyses on cores from 3 lakes in the White Mountains of New Hampshire. Paleoenvironmental reconstructions will be based on the following proxy records: (1) sediment lithology and percent organic matter - erosion rates and terrestrial and aquatic productivity; (2) chironomids - maximum summer water temperatures; and (3) pollen and plant macrofossils (stomates, needles and seeds) - vegetation and changes in species range limits. The goal of this research is to determine whether the cold events and millennial scale climate variability observed in the North Atlantic affected the environment of the White Mountains of New Hampshire. .
