Collaborative Proposal: CUAHSI/CLEANER Demonstration and Development of a Test-bedDigital Observatory for the Susquehanna River Basin and Chesapeake BayIntroduction: The proposed project will demonstrate the applicability and utility of a EnvironmentalDigital Observatory (EDO) design whose components are currently being developed by the HydrologicInformation System (HIS) group of CUAHSI for use by both the CLEANER and CUAHSI communities.While the 4 components of the EDO system have been identified (Environmental Digital Library (EDL),Environmental Observations Database (EOD), Digital Environment-Shed (DES), Environmental AnalysisSystem (EAS)), only some of the components are currently in a state to be deployed in a beta-testingmode, most notably the EDL and to some extent the DES. Because of the complexity of the systemcomponents it is impossible to produce a roll-out product that would meet all the expectations from thestart. Hence, it is crucial that these components are put to a test in a test-bed environment to investigatehow the components behave, what pieces are missing, what additional developments need to be carriedout, and most importantly whether they are effective for the purpose they were designed. Because of theenvisioned scope in funding and time as well as the availability and current state of the developments, thisproject will focus on the first of the components (the EDL), which constitutes the base layer upon whichall of the other components rest.Objectives: The objectives are to: (1) test and demonstrate the usefulness of a EDL for inclusion in theEDO as applied to nutrient fluxes in both the Susquehanna River Basin (SRB) and Chesapeake Bay (CB)for which a data gap analysis will be performed (2) demonstrate the feasibility of using existing CIcomponents (EDO from CUAHSI and CyberCollaboratory from CLEANER) to meet a merged andoverlapping science agenda as demonstrated on the SRB/CB test-bed, and (3) further develop and extendexisting components as well as provide feedback on the design and functionality of CI components to thetechnology partners at SDSC and NCSA.Methodology: To accomplish these objectives an instance of the EDL will be installed at DrexelUniversity. Together with the project partners representing an upstream Hydrologic Observatory regionand a downstream Environmental Observatory region, we will identify and collect as many nutrient dataas is possible and currently available for these regions for inclusion in the EDL. While the population ofthe EDL in the first step will require substantial effort to further develop current CI components(appropriate metadata tags and tools for creating instantiations) we will conduct a data gap analysis in theupstream region for missing or insufficient data. The gap analysis will be carried out using a statisticalmodeling tool (SPARROW), which will yield predictions that can be compared to existing data sets. Thequality or match of these comparisons will be an indicator for the overall quality of the data sets as far astheir temporal and spatial coverage is concerned. This is an important step towards an improvedknowledge on the fluxes, stores, and pathways of water as well as nutrients within the SRB and thereceiving waters of the CB.Intellectual merit: This project would be the first effort to investigate how hydrologists andenvironmental engineers can make use of the suite of technical support applications currently underdevelopment. This is a crucial step in further developing CI for the environmental and hydrologycommunities by providing feedback in a beta-testing mode. In addition, the use of the CyberCollaboratoryprototype will allow the project team to test a collaboratory system while executing a research project aswell as generate valuable information on how well the system can be used for the purpose of supportingobservatory science and design. Both systems are IT cornerstones for a shared CI between and CUAHSIand CLEANER and as such must be evaluated before being released to the communities.Broader impacts: Besides the impact this project will have on the CI development for hydrologic andenvironmental engineering communities in identifying future research needs, it will also address theeducational sector. One of the major goals of both communities is to bring water related data and toolsinto the class room as well to i) better train the future workforce on issues related to water, and ii) toexpose them to aspects of information technology that could place future professionals at the interface ofwater and IT, an educational goal that has been identified by the NSF Blue Ribbon Advisory Panel onCyberinfrastructure as being one of the most pressing educational needs of the future.

合作方案：CUAHSI/CIRER演示和开发苏斯奎哈纳河流域和切萨皮克湾的试验台数字天文台简介：拟议的项目将展示环境数字天文台(EDO)设计的适用性和实用性，其组件目前正由CUAHSI的水文信息系统(HIS)小组开发，供CLEAR和CUAHSI社区使用。虽然EDO系统的4个组件(环境数字图书馆(EDL)、环境观测数据库(EOD)、数字环境分水岭(DES)、环境分析系统(EAS))已确定，但目前只有一些组件处于测试模式最值得注意的是EDL，在某种程度上也是DES。由于系统组件的复杂性，不可能生产出从一开始就满足所有期望的推出产品。因此，关键是要在试验台环境中对这些组件进行测试，以调查这些组件如何运行、缺少哪些部件、需要进行哪些额外的开发，以及最重要的是，它们是否有效地达到了设计的目的。由于资金和时间方面的设想范围以及开发的可获得性和现状，该项目将侧重于第一个组成部分(EDL)，目标：(1)测试和演示EDL在苏斯奎汉纳河流域(SRB)和切萨皮克湾(CB)营养盐通量中的应用的有用性，并对其进行数据差距分析(2)论证使用现有的CI组件(来自CUAHSI的EDO和来自CLEANER的CyberCollab)来满足在SRB/CB试验台上演示的合并和重叠的科学议程的可行性，以及(3)进一步开发和扩展组件，并向SDSC和NCSA的技术合作伙伴提供关于CI组件的设计和功能的反馈。方法：为了实现这些目标，将在DrexelUniversity安装EDL的实例。我们将与代表上游水文观测区和下游环境观测区的项目合作伙伴一起，确定和收集尽可能多和目前可用于这些地区的营养数据，以纳入EDL。虽然在第一步中填充EDL将需要付出大量努力来进一步开发当前的CI组件(创建实例化的适当元数据标记和工具)，但我们将在上游区域进行数据差距分析，以发现丢失或数据不足的情况。差距分析将使用统计建模工具(Sparrow)进行，该工具将产生可与现有数据集进行比较的预测。就时间和空间复盖面而言，这些比较的质量或匹配性将是数据集的整体质量的一个指标。这是朝着更好地了解SRB和CB接收水中的水的通量、储存和路径以及营养物质迈出的重要一步。这是通过以测试版模式提供反馈，进一步为环境和水文社区制定传播与信息计划的关键一步。此外，网络协作原型的使用将使项目组能够在执行研究项目的同时测试合作系统，并产生关于该系统在多大程度上可用于支持天文台科学和设计的宝贵信息。这两个系统都是和CUAHS和CLEANER之间共享CI的IT基石，因此在发布给社区之前必须进行评估。广泛影响：除了该项目将对水文和环境工程社区在确定未来研究需求方面的CI发展产生影响外，它还将针对教育部门。这两个社区的主要目标之一是将与水有关的数据和工具带到课堂上，以便i)更好地培训未来的劳动力与水有关的问题，以及ii)使他们接触到信息技术的各个方面，使他们能够接触到未来的专业人员与水和信息技术的接口，这一教育目标已被国家科学基金会网络基础设施蓝带咨询小组确定为未来最紧迫的教育需求之一。
