Boulder Creek CZO Renewal: Weathered Profile Development in a Rocky Environment and Its Influence on Watershed Hydrology and Biogeochemistry

博尔德溪临界带观测站的建立是为了探索不同侵蚀历史下临界带的演变和功能。监测基础设施已建立在三个子集水区博尔德河，在他们的侵蚀制度显著不同。目前正在收集气象强迫的时间序列，以及流域的水文、地貌和生态反应。研究的重点是这些过程之间的相互作用。根据该奖项，该团队将深化他们在水文相互作用和分区、风化和移动风化层产生、树木作为风化层发育的媒介、景观级生物地球化学和微生物动力学、火灾和景观干扰以及景观演变等相互关联的主题上的研究。博尔德溪临界区天文台（BcCZO）的研究考察了地球的演化和功能。关键区域？位于植被顶部和风化基岩底部之间的薄薄的地表。该小组将研究水文过程，树木在形成风化层中的作用，以及火灾等罕见事件在景观发展中的作用。在接下来的一年里，BcCZO将继续让研究人员和学生接触到关键区域科学，并为更广泛的科学界生成数据集。科学的过程和发现通过几种途径直接向公众展示。其中包括通过学生-教师研讨会和与科罗拉多大学科学发现项目合作举办的夏令营提供的中学水平的研究性课程；高中生暑期研究经验，也与CU科学发现；在夏季为本科生提供凯克地质学项目的研究经验；由中国计算机科学研究院主办的关键区域网络系列研讨会；还有一个网站。

The Boulder Creek Critical Zone Observatory was established to explore the evolution and function of the critical zone under differing erosion histories. Monitoring infrastructure has been established in three sub-catchments of Boulder Creek that differ significantly in their erosional regime. Time series of meteorological forcing, and the hydrologic, geomorphic and ecological response of the catchment are now being collected. Research focuses on interactions among these processes. Under this award, the team will deepen their research on interconnected topics of hydrologic interactions and partitioning, weathering and mobile regolith production, trees as agents of regolith development, landscape-level biogeochemical and microbial dynamics, fire and landscape disturbance, and landscape evolution. The research at Boulder Creek Critical Zone Observatory (BcCZO) examines the evolution and function of Earth?s Critical Zone?the thin veneer of Earth between the top of the vegetation and the base of weathered bedrock. The team will examine hydrologic processes, the roles of trees in developing regolith, and the role of infrequent events such as fires in landscape development. Over the coming year, the BcCZO will continue to expose researchers and students to critical zone science and generate datasets for the broader scientific community. The process of science and the discoveries made are taken directly to the public through several avenues. These include research-based curriculum at middle-school level offered through student-teacher workshops and a summer day camp, run in partnership with the CU Science Discovery program; summer research experience for high school students, also with CU Science Discovery; the Keck Geology Program research experience for undergraduates during the summer; the Critical Zone Cyber-seminar series, hosted by CUAHSI; and a website.
