Landscape evolution and adapting to change in ice-rich permafrost systems, Prudhoe Bay, Alaska, 2023-2024

This project is part of Navigating the New Arctic (NNA) which addresses converging scientific challenges in the rapidly changing Arctic. Specifically, the goal of this project is to better understand ice-rich permafrost at local, regional, and circumpolar scales. This dataset provides ground temperature data in the active layer and near-surface permafrost to provide a baseline for assessing the future changes in the near-surface temperatures in the natural environment and next to the infrastructure/disturbed environment at Prudhoe Bay, Alaska. Collected ground temperature data are intended to help researchers, communities and public with ongoing activities to mitigate a threat of thawing permafrost on the local and regional scale, and to provide spatial data for validation of climate scenario models and temperature reanalysis approaches.本项目隶属于“新北极航行计划（Navigating the New Arctic, NNA）”，该计划旨在应对快速变化的北极地区所面临的多重交织科学挑战。具体而言，本项目的目标是在局地、区域乃至环北极尺度上，深化对富冰多年冻土（ice-rich permafrost）的认知。本数据集提供了活动层（active layer）与近地表多年冻土（near-surface permafrost）的地面温度数据，可为评估阿拉斯加州普拉德霍湾（Prudhoe Bay）自然环境以及基础设施/受扰动环境的近地表温度未来变化提供基准。所采集的地面温度数据，旨在助力研究人员、当地社区及公众开展相关活动，以缓解局地与区域尺度多年冻土融化带来的威胁，同时可为气候情景模型与温度再分析方法的验证提供空间数据支撑。
