This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project will establish a monitoring network in two watersheds of the Luquillo National Forest in Puerto Rico to evaluate the physical, chemical, hydrological and biological processes involved in weathering of bedrock and the evolution of the soil environment. This will be an addition to the Critical Zone Observatories (CZO) that are being initiated at various locations in North America. The Luquillo CZO will use the natural laboratory of the Luquillo Mountains to quantify and contrast how critical zone processes in watersheds underlain by granodiorite and volcaniclastic bedrock are affected by climatic conditions and hydrologic, geochemical and biogeochemical cycles. A set of interrelated hypothesis, sampling sites, and a unified data management system will allow critical zone processes to be contrasted by bedrock, landscape position (ridge, hillslope, riparian), depth (surface to bedrock), forest type (Tabonuco, Colorado, Cloud) and location (upland to coastal). Changing climate affects many processes, and the breakdown of rocks into soil; is one of the most important. In addition, there may be changes in water flow in rivers, as well as erosion of surficial materials. Sediment is already the nation's largest water quality pollutant and modern land uses are eroding soils and sculpting bedrock in unprecedented ways. The Luquillo Critical Zone Observatory will provide the infrastructure and baseline studies needed to evaluate short and long-term impacts of this erosion on soil and water resources. The Observatory will also support integrated, multi-institutional and multicultural exchanges among a diverse cadre of scientists, who will collaborate to determine the effects of climate change on the terrestrial environment.

该奖项是根据2009年的《美国回收与重新投资法》（公法111-5）资助的。该项目将在波多黎各的卢奎洛国家森林的两个分水岭建立一个监测网络，以评估涉及底层泳衣和土壤环境的物理，化学，化学，水文，水文和生物过程。这将是在北美各个地方启动的关键区域观测站（CZO）的补充。 Luquillo CZO将使用Luquillo山脉的自然实验室来量化和对比，并对比核酸层和火山碎裂基岩在气候条件下以及水文，地球化学和生物地球化学周期的关键区域过程如何受到花岗闪石和火山碎裂基岩的影响。 一组相互关联的假设，采样位点和统一的数据管理系统将允许关键区域过程与基岩，景观位置（山脊，山坡，河岸，河岸），深度（地表到基岩），森林类型（Tabonuco，tabonuco，colorado，colorado，Colorado，cloud）和位置（上位于沿海地）对比。 气候变化会影响许多过程，并将岩石分解为土壤；是最重要的之一。此外，河流的水流可能会发生变化，以及表面材料的侵蚀。沉积物已经是美国最大的水质污染物，现代土地用途是以前所未有的方式侵蚀土壤和雕刻基岩。 Luquillo关键区观测站将提供评估这种侵蚀对土壤和水资源的短期和长期影响所需的基础设施和基线研究。天文台还将支持各种科学家干部之间的综合，多机构和多元文化交流，他们将合作确定气候变化对陆地环境的影响。
