Collaborative Research: Integrated Data Management for Hydrothermal Spring Geochemistry

智力优势：热液泉地球化学数据管理系统？叫VentDB ？将开放获取从所有构造环境中获得的海底热液喷口的全部成分数据。该系统将允许对热液泉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集成。VentDB将包含所有已发布的历史数据，以及研究人员将提供的遗留数据和新数据。VentDB将作为哥伦比亚大学的Lamont-Doherty地球观测站（LDEO）和国际地球信息网络中心（CIESIN）与夏威夷大学合作的地球化学地球信息学项目的一部分进行开发和管理。VentDB以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为模型，提供了对综合地球化学数据集的快速、简单和灵活的访问，用户可以通过数据库中包含的必要补充信息（元数据）从中提取针对其特定科学问题定制的任何数据子集。该项目的可交付成果包括数据库的实现及其具有综合遗留数据集的人口、基于web的用户界面的开发以及用于访问客户端系统所持有的数据的web服务。VentDB系统的开发将利用面向服务体系结构（SAO）的现有系统组件，该组件应用于地球化学项目的地理信息学的所有数据系统。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和边际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MGDS协调。海底热液泉的化学数据是研究洋中脊和海底过程、海水化学、全球地球化学循环以及喷口生态系统和海底生物圈的基础。通过方便获取全球热液泉地球化学数据集，VentDB将对全球地球化学、微生物学和矿床研究产生重大影响。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，它将成为增强我们对地球系统理解的主要工具。我们期望这个项目将产生许多新的基本见解和意想不到的结论，这些只能通过使用大型数据库得出，就像我们在PetDB数据库中看到的那样。更广泛的影响：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。通过使学生容易获得科学数据，它们正在课程中使用，并使地球科学学生对数据操作和解释有了新的认识。研究人员整合不同数据类型的能力增强，将带来有助于更好地了解地球和生态系统的发现。

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.
