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.

该奖项为一个项目提供了一个项目，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海事省，明尼苏达州北部和安大略省的泥炭地地区进行多种古气候研究。稳定的同位素研究将检查杂菌营养泥炭地的独特水文，并进一步了解基于树木环和花粉的全新世气候变化。来自该地区的大多数树环记录仅扩展了几个世纪，花粉序列记录对气候变化的响应，但通常会滞后和/或掩盖式变化。研究人员旨在开发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3000年的气候变异性。该研究将有助于量化森林生态系统的区域反应，以便为气候变化和支持跨学科的培训，以识别跨学科的培训，以供一名后疾病研究人员和几名学生和几名学生。
