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，以完成克里斯蒂娜河盆地（CRB）关键区观测站（CZO）和NSF奖0724971的投资。CRB-CZO的总体科学目标是在2009年建立的，以测试两个相关的相关假设：1）生产和生物学量表，并结合了化学量和生物学型号，并结合了化学量和生物学型号的矿物质。风化，土壤生产和碳固执；和：2）人类加速碳矿物质混合速率，从而导致人为碳固相对于本地，区域和全球预算显着。 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 &对碳矿物质供应，混合和埋葬的沉积控制，以及4）腐生的腐生腐蚀碳隔离的腐生。 CRB-CZO研究研究了从单个矿物晶粒到整个流域的量表，涉及现场，实验室和建模方法。 这项为期1年的奖项将资助来自5个机构的14名调查人员，以最终对这些主题进行持续的研究。此外，CRB-CZO团队还将最终确定具有不同“终结者”土地用途（森林，农业和受干扰）的溪流中的传感器站安装，以此作为对未来研究的投资。 该研究计划还概述了超越NSF CZO计划的持续资金的机会。 根据该为期1年奖励的CRB-CZO研究活动将最终培训大约8位博士学位学生，并在科学会议上在同行评审的期刊和演讲中提供许多出版物。 CRB-CZO将在可能的情况下继续与国家CZO网络（包括国家CZO办公室）进行通信和协调。 调查人员还将在2014年秋季组织一次克里斯蒂娜河流域科学和管理研讨会。研讨会将向包括克里斯蒂娜盆地水质管理委员会在内的各种利益相关者强调CRB-CZO研究，其中包括来自15位联邦，州和地方环境资源机构的代表。
