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年美国复苏和再投资法案（公法111-5）资助的，该项目将在波多黎各的卢基略国家森林的两个流域建立监测网络，以评估基岩风化和土壤环境演变所涉及的物理、化学、水文和生物过程。这将是对在北美各地启动的临界区观测站的补充。 卢基略CZO将利用卢基略山脉的天然实验室，量化和对比气候条件和水文、地球化学和地球化学循环对花岗岩和火山岩基岩下流域关键区过程的影响。 一套相互关联的假设、取样地点和统一的数据管理系统将使关键地带的过程能够根据基岩、景观位置（山脊、山坡、河岸）、深度（地表到基岩）、森林类型（塔博努科、科罗拉多、云）和位置（高地到沿海）进行对比。 气候变化影响许多过程，岩石分解成土壤是最重要的过程之一。此外，河流中的水流可能会发生变化，表层物质也会受到侵蚀。沉积物已经是美国最大的水质污染物，现代土地使用正在以前所未有的方式侵蚀土壤和雕刻基岩。卢基略临界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。该观测站还将支持各种科学家之间的综合、多机构和多文化交流，他们将合作确定气候变化对陆地环境的影响。
