Active Layer/Landscape Interactions: A Retrospective and Contemporary Regional Approach in Arctic Alaska

该奖项是北极系统科学（ARCSS）计划的一部分， 美国全球变化计划 该研究项目涉及的变化 活动层厚度的季节性变化 阿拉斯加北极地区的典型气候。 网络 长期观测点，位于历史上 将建立以前的研究和数据。 主要重点 这项研究的一部分将是永久冻土层上的一层薄薄的土壤 每年解冻和冻结，被称为 “活动层”。 这个土壤活性层介导生物， 地球化学、水文、地貌和其他热量和质量 转移过程。 这个项目是一个更大的 这是一个跨学科的项目，被称为ARCSS FLUX项目。

This award is part of the Arctic System Science (ARCSS) Program, a U.S. Global Change Program. The research project relates changes in the thickness of the active layer to variations in seasonal climate across representative Arctic Alaska landscapes. A network of long-term observational sites, based at locations with histories of prior studies and data will be established. The primary focus of this study will be a thin layer of soil above the permafrost which thaws and freezes on an annual basis and is known as the "active layer". This soil-active layer mediates biological, biogeochemcial, hydrological, geomorphic, and other heat and mass transfer processes. This project is a component of a larger interdisciplinary program known as the ARCSS FLUX Program.
