This 1-year project represents a plan to complete the investments made in the Christina River Basin (CRB) Critical Zone Observatory (CZO) with NSF award 0724971. The overarching scientific objectives of the CRB-CZO were established in 2009 to test two related hypotheses: 1) Hydrological, chemical, and biological processes that produce and mix mineral surfaces and organic carbon are rate limiting to watershed scale chemical weathering, soil production, and carbon sequestration; and: 2) Humans accelerate rates of carbon-mineral mixing, resulting in anthropogenic carbon sequestration significant to local, regional, and global budgets. The extended CRB-CZO team examined these hypotheses within the 6th-order CRB watershed of Southeastern Pennsylvania and Southern Delaware with a suite of long-term studies organized into 4 inter-related objective areas: 1) Carbon-mineral-microbe-water interactions, 2) Co-evolution of critical zone structure, hydro-bio-geo-chemical function and carbon complexation, 3) Mobilization, transport & depositional controls on carbon-mineral supply, mixing, and burial, and 4) Saprolite to sea integration of erosion-driven carbon sequestration. CRB-CZO studies investigate scales varying from individual mineral grains to entire watersheds, and involve field, lab, and modeling approaches. This 1-year award will fund 14 investigators from 5 institutions to finalize ongoing research on these topics. In addition, the CRB-CZO team will also finalize installation of sensor stations in the streams draining study watersheds with different "endmember" land uses (forest, agriculture, and disturbed) as an investment in future studies. The research plan also outlines opportunities to pursue ongoing funding beyond the NSF CZO program. CRB-CZO research activities under this 1-year award will finalize training of approximately 8 PhD students and result in numerous publications in peer-reviewed journals and presentations at scientific meetings. CRB-CZO will, to the extent possible, continue to communicate and coordinate with the national CZO network (including the national CZO office). Investigators will also organize a Christina River Basin Science and Management Symposium in the Fall of 2014. The Symposium will highlight CRB-CZO research to a variety of stakeholders, including the Christina Basin Water Quality Management Committee, which includes representatives from 15 federal, state, and local environmental resource agencies.

这个为期一年的项目代表了一项计划，旨在完成对克里斯蒂娜河流域 (CRB) 关键区域观测站 (CZO) 的投资，并获得 NSF 奖项 0724971。CRB-CZO 的总体科学目标于 2009 年制定，旨在检验两个相关假设：1) 产生和混合矿物表面和有机碳的水文、化学和生物过程限制了流域规模的化学风化、土壤生产和碳的速率扣押； 2) 人类加速了碳-矿物混合的速度，导致人为固碳，对地方、区域和全球预算具有重要意义。 扩大的 CRB-CZO 团队在宾夕法尼亚州东南部和特拉华州南部的 6 级 CRB 流域内检验了这些假设，并进行了一系列长期研究，这些研究分为 4 个相互关联的目标领域：1）碳-矿物质-微生物-水相互作用， 2) 关键带结构、水文生物地球化学功能和碳络合的共同演化，3) 对碳-矿物供应、混合和沉积的动员、运输和沉积控制掩埋，4) 腐泥土与侵蚀驱动的碳封存的海洋整合。 CRB-CZO 研究调查的范围从单个矿物颗粒到整个流域，涉及现场、实验室和建模方法。 该奖项为期 1 年，将资助来自 5 个机构的 14 名研究人员完成这些主题的持续研究。此外，CRB-CZO 团队还将最终确定在具有不同“最终成员”土地用途（森林、农业和干扰）的研究流域的河流中安装传感器站，作为对未来研究的投资。 该研究计划还概述了在 NSF CZO 计划之外寻求持续资助的机会。 CRB-CZO 为期一年的研究活动将完成大约 8 名博士生的培训，并在同行评审期刊上发表大量出版物并在科学会议上进行演示。 CRB-CZO 将尽可能继续与国家 CZO 网络（包括国家 CZO 办公室）进行沟通和协调。 研究人员还将在 2014 年秋季组织一次克里斯蒂娜河流域科学与管理研讨会。该研讨会将向各种利益相关者重点介绍 CRB-CZO 研究，其中包括克里斯蒂娜河流域水质管理委员会，该委员会包括来自 15 个联邦、州、和当地环境资源机构。
