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

博尔德溪临界区观测站的建立是为了探索不同侵蚀历史下临界区的演变和功能。已在博尔德溪的三个子流域建立了监测基础设施，这些流域的侵蚀状况存在显着差异。目前正在收集气象强迫的时间序列，以及集水区的水文、地貌和生态响应。研究的重点是这些过程之间的相互作用。根据该奖项，该团队将深化对水文相互作用和分区，风化和移动的风化层生产，树木作为风化层发展的代理人，植被水平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。的临界区？植被顶部和风化基岩底部之间的薄土层。 该小组将研究水文过程，树木在发展风化层中的作用，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临界区科学，并为更广泛的科学界生成数据集。 科学的进程和发现通过多种途径直接向公众展示。其中包括通过师生研讨会和夏令营提供的中学水平的研究型课程，与CU科学发现计划合作;高中生的夏季研究经验，也与CU科学发现;凯克地质计划研究经验本科生在夏季;临界区网络研讨会系列，由CUAHSI主办;和一个网站。

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.
