Collaborative Research: Integrated Data Management for Hydrothermal Spring Geochemistry

智慧价值：热液泉水地球化学数据管理系统？叫VentDB？将建立可开放查阅从所有构造环境获得的海底热液喷口的各种成分数据。该系统将允许对有关热液泉水和羽流的遗留和未来分析数据进行专业存档、管理、服务，并与相关喷口数据和更广泛的地球科学数据集相结合。VentDB将包含所有已发布的历史数据，以及调查人员将贡献的旧数据和新数据。VentDB将作为哥伦比亚大学Lamont-Doherty地球天文台(LDEO)和国际地球信息网络中心(CIESIN)的地球化学地球信息学计划的一部分，与夏威夷大学合作开发和管理。VentDB仿照了成功的火成岩和变质岩地球化学在线数据库PetDB和新兴的海洋沉积物地球化学数据管理系统SedDB，提供了对综合地球化学数据集的快速、方便和灵活的访问，用户可以通过数据库中包含的必要补充信息(元数据)从其中提取针对其特定科学问题定制的任何数据子集。项目可交付成果包括利用综合遗留数据集实施数据库及其人口，开发基于网络的用户界面，以及为客户系统访问所持有的数据提供网络服务。VentDB系统的开发将利用面向服务架构(SAO)的现有系统组件，该架构适用于地球化学地球信息学方案的所有数据系统。用户界面将以交互式查询工具、交互式地图以及数据质量评估和数据分析工具为特色。它将与地球化学、海洋地球科学数据系统MGDS(包括Ridge2000和Markets DMS)中的其他地球化学、地质、地球物理和生物数据密切联系和集成。调查人员提交新数据的程序将与全球海洋观测系统协调。海底热泉的化学数据是研究大洋中脊和海底过程、海水化学、全球地球化学循环以及喷口生态系统和海底下生物圈的基础。通过促进对全球热液温泉地球化学数据集的访问，VentDB将对全球地球化学、微生物学和矿床研究产生重大影响。它将是通过允许研究人员整合数据类型和开发新的跨学科方法来解决科学问题，从而加强我们对地球系统的了解的主要工具。我们预计这个项目将产生许多只有通过使用大型数据库才能得出的新的基本见解和意想不到的结论，就像我们在PetDB数据库中看到的那样。广泛的影响：利用严格的数据管理技术、交换工具(如标记语言)、知识网络、数据挖掘和复杂的可视化工具的信息系统的发展对地球化学数据在研究和地球科学教育中的应用产生了重大影响。通过让学生更容易地获取科学数据，这些数据被用于课程，并让地球科学专业的学生对数据处理和解释有了新的理解。研究人员整合不同数据类型的能力的增强将导致发现，从而更好地了解地球和生态系统。

Intellectual Merit: A data management system for hydrothermal spring geochemistry ? called VentDB ? will be established for open access to the full range of compositional data acquired on seafloor hydrothermal vents from all tectonic settings. This system will allow legacy and future analytical data on hydrothermal springs and plumes to be professionally archived, managed, served, and integrated with related vent data and the broader Geoscience data set. VentDB will contain all published historical data as well as legacy and new data that investigators will contribute. VentDB will be developed and managed as part of the Geoinformatics for Geochemistry Program at the Lamont-Doherty Earth Observatory (LDEO) and the Center for International Earth Information Network (CIESIN), both at Columbia University, in collaboration with the University of Hawaii. VentDB is modeled after the successful online database for igneous and metamorphic rock geochemistry, PetDB, and the emerging data management system for marine sediment geochemistry, SedDB, providing fast, easy, and flexible access to integrated geochemical data sets from which users can extract any subset of data customized to their specific scientific problem, by means of the requisite supplementary information (metadata) that will be included in the database. The project deliverables encompass the implementation of the database and its population with a comprehensive legacy data set, the development of a web-based user interface and of web services for access to data holdings by client systems. The development of the VentDB system will make use of existing system components of the Service Oriented Architecture (SAO) that is applied to all data systems of the Geoinformatics for Geochemistry program. The user interface will feature interactive query tools, interactive maps, and tools for data quality evaluation and data analysis. It will be intimately linked and integrated with other geochemical, geological, geophysical, and biological data in EarthChem, the Marine Geoscience Data System MGDS (which includes the Ridge2000 and MARGINS DMS). Procedures for submission of new data by investigators will be coordinated with the MGDS.Chemical data for seafloor hydrothermal springs are fundamental to the study of mid-ocean ridge and seafloor processes, ocean water chemistry, global geochemical cycles, as well as vent ecosystems and sub-seafloor biospheres. By facilitating access to the global geochemical data set for hydrothermal springs, VentDB will have a major impact on global geochemistry, microbiology, and ore deposits research. It will be a primary vehicle to enhance our understanding of the Earth System by allowing researchers to integrate data types and develop new cross-disciplinary approaches to scientific questions. We expect this project will result in many new fundamental insights and unanticipated conclusions that can only be drawn by the use of large databases, as we have seen for the PetDB database.Broader Impacts: The development of information systems that make use of rigorous data management technologies, interchange tools such as markup languages, knowledge networking, data mining, and sophisticated visualization tools has a major impact on the application of geochemical data in research and Earth science education. By making scientific data easily accessible to students, they are being used in courses and giving Earth science students new appreciation for data manipulation and interpretation. The enhanced ability of researchers to integrate diverse data types will result in discoveries leading to better understanding of the Earth and eco-systems.
