Collaborative Research: Multiproxy Archives of Late Holocene Climate Variability from Ombrotrophic Peatlands in Eastern North America

该奖项资助了一个调查北美东部泥炭地作为气候信息档案的利用的项目。研究人员将在加拿大沿海省份、明尼苏达州北部和安大略省西南部的泥炭地地区进行多代理古气候研究。稳定同位素研究将考察营养丰富的泥炭地独特的水文学，并进一步了解基于树木年轮和花粉的晚全新世气候变异性。该地区的大多数年轮记录只持续了几个世纪，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3000年的气候变化。这项研究将有助于量化区域森林生态系统对气候变化的反应，并支持对一名博士后研究员和几名本科生进行跨学科培训。

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.
