This award funds a project to investigate the utility of peatland in eastern North America as archives of climate information. The researchers will conduct multi-proxy paleoclimate studies in peatland areas located in the Canadian Maritime provinces, northern Minnesota, and southwest Ontario. Stable isotope studies will examine the unique hydrology of ombrotrophic peatlands and further understand late Holocene climate variability based on tree-rings and pollen. Most tree-ring records from the region extend only a few centuries and pollen sequences record responses to climate change but often lag and/or mask abrupt changes. The researchers aim to develop high-resolution and climate-sensitive datasets from peatlands to document climate variability during the past 3,000 years in the region.The research will help quantify regional responses of forest ecosystems to climate change and support interdisciplinary training for a post-doctoral researcher and several undergraduate students.

该奖项资助了一个项目，以调查北美东部泥炭地作为气候信息档案的效用。研究人员将在位于加拿大沿海省份、明尼苏达州北方和安大略西南部的泥炭地地区进行多代理古气候研究。稳定同位素研究将检查湿润泥炭地的独特水文，并根据树木年轮和花粉进一步了解全新世晚期的气候变化。该地区的大多数树木年轮记录只延续了几个世纪，花粉序列记录了对气候变化的反应，但往往滞后和/或掩盖了突然的变化。研究人员的目标是从泥炭地开发高分辨率和气候敏感的数据集，以记录该地区过去3,000年的气候变化。这项研究将有助于量化森林生态系统对气候变化的区域响应，并支持对博士后研究人员和几名本科生的跨学科培训。
