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.

合作提案：CUAHSI/CLEANER 萨斯奎哈纳河流域和切萨皮克湾试验台数字观测站的演示和开发简介：拟议项目将演示环境数字观测站 (EDO) 设计的适用性和实用性，其组件目前由 HydrologicInformation 开发CUAHSI 的系统 (HIS) 组，供 CLEANER 和 CUAHSI 使用虽然 EDO 系统的 4 个组成部分已经确定（环境数字图书馆（EDL）、环境观测数据库（EOD）、数字环境棚（DES）、环境分析系统（EAS）），但目前只有部分组成部分处于以 Beta 测试模式部署的状态，最引人注目的是 EDL，在某种程度上是 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，至关重要的是，必须在测试台环境中对这些组件进行测试，以研究组件的行为方式、缺少哪些部分、需要进行哪些额外开发，以及最重要的是它们是否能够有效地实现其预期目的设计的。由于预期的资金和时间范围以及开发的可用性和当前状态，该项目将重点关注第一个组件（EDL），它构成了所有其他组件所依赖的基础层。目标是： (1) 测试并证明将 EDL 纳入 EDO 应用于萨斯奎哈纳河流域 (SRB) 和切萨皮克湾 (CB) 养分通量的有用性，其中将进行数据差距分析 (2) 证明使用现有 CI 组件（CUAHSI 的 EDO 和 CLEANER 的 Cyber​​Collaboratory）满足 SRB/CB 测试台上演示的合并和重叠科学议程的可行性，以及 (3) 进一步开发和扩展现有组件，并向 SDSC 和 NCSA 的技术合作伙伴提供有关 CI 组件的设计和功能的反馈。方法：为了实现这些目标，将在以下位置安装 EDL 实例：德雷塞尔大学。我们将与代表上游水文观测站区域和下游环境观测站区域的项目合作伙伴一起，确定并收集尽可能多的营养物数据，这些数据目前可用于这些区域，以纳入 EDL。虽然第一步中 EDL 的填充需要付出大量努力来进一步开发当前的 CI 组件（适当的元数据标签和用于创建实例的工具），但我们将在上游区域进行数据缺口分析，以查找缺失或不足的数据。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。就其时间和空间覆盖范围而言，这些比较的质量或匹配将成为数据集整体质量的指标。这是朝着提高对 SRB 和 CB 接收水中的水和营养物的通量、储存和路径的认识迈出的重要一步。 智力价值：该项目将是第一个研究水文学家和环境工程师如何使使用目前正在开发的技术支持应用程序套件。这是通过以 beta 测试模式提供反馈进一步开发环境和水文学界 CI 的关键一步。此外，使用网络协作原型将使项目团队能够在执行研究项目时测试协作系统，并生成有关该系统如何用于支持天文台科学和设计的有价值的信息。这两个系统都是 CUAHSI 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。更广泛的影响：除了该项目还将对水文和环境工程社区的 CI 开发确定未来研究需求产生影响之外，它还将涉及教育部门。这两个社区的主要目标之一是将与水相关的数据和工具带入课堂，以便 i) 更好地培训未来的劳动力有关水的问题，以及 ii) 让他们接触信息技术的各个方面，从而为未来的专业人员提供培训NSF 蓝丝带网络基础设施咨询小组已将这一教育目标确定为未来最紧迫的教育需求之一。
