Collaborative Research: An Environmental Information System for Hypoxia in Corpus Christi Bay: A WATERS Network Testbed

[0610034]本提案寻求资金用于创建和演示环境信息系统（EIS）的原型，该系统将传感器测量与端到端网络基础设施相结合，以提高对德克萨斯州科珀斯克里斯蒂湾（CC湾）缺氧的了解。缺氧是沿海水域的常见问题，当溶解氧浓度低于2毫克/升时就会发生。以往的实地研究表明，缺氧导致CC湾的底栖生物存量和多样性减少了约10倍。海湾缺氧与盐度引起的海湾分层有关，但分层的原因和缺氧的时空格局尚不清楚。一个由水文学家、环境工程师和生物学家组成的跨学科团队将合作：(1)评估如何使用传感器数据来指导自适应采样；(2)建立改进的缺氧模型，将数值水动力和氧气模型与数据挖掘方法相结合；(3)展示如何将这些信息源整合到新兴的网络基础设施工具中，以创建环境影响报告书，以提高对海湾缺氧的了解。该项目旨在作为更广泛地使用环境信息系统进行合作研究和决策支持的原型示范。这个合作项目是一系列试验台项目中的一个，这些项目是为了支持WATERS网络的技术开发而资助的，该网络是美国国家科学基金会的一个分布式环境观测倡议。

0610034MaidmentThis proposal seeks funds to create and demonstrate a prototype Environmental Information System (EIS) that couples sensor measurements with end-to-end cyberinfrastructure to improve understanding of hypoxia in Corpus Christi Bay (CC Bay), Texas. Hypoxia is a common problem in coastal waters that occurs when dissolved oxygen concentrations fall below 2 mg/L. Previous field studies indicate that hypoxia has caused about a ten-fold reduction in benthic standing stock and diversity in CC Bay. Hypoxia in the bay has been correlated with salinity-induced stratification of the bay, but causes of stratification and the spatial and temporal patterns of the hypoxia remain uncertain. An interdisciplinary team of hydrologists, environmental engineers, and biologists will collaborate to: (1) evaluate how sensor data can be used to guide adaptive sampling; (2) create improved models of hypoxia, coupling numerical hydrodynamic and oxygen models with data-mining methods; and (3) demonstrate how these information sources can be integrated into emerging cyberinfrastructure tools to create an EIS to improve understanding of hypoxia in the bay. The project is intended as a prototype demonstration on the broader use of the EIS for collaborative research and decision support. This collaborative project is one of a series of test-bed projects funded to support the development of enabling technologies for the WATERS Network, a distributed environmental observatory initiative of NSF.
