Collaborative Research: Integrated Data Management for Hydrothermal Spring Geochemistry

知识价值：将建立一个热液泉地球化学数据管理系统-称为VentDB -以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。这一系统将使关于热液泉和羽流的传统和未来分析数据得到专业存档、管理和服务，并与有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研究人员将贡献的旧数据和新数据。VentDB将在哥伦比亚大学的拉蒙特-多尔蒂地球观测站和国际地球信息网中心与夏威夷大学合作，作为地球化学地理信息方案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，提供快速，轻松和灵活的综合地球化学数据集访问，用户可以从中提取任何针对其特定科学问题定制的数据子集，通过将纳入数据库的必要补充信息（元数据）。该项目的交付成果包括实施数据库并将其纳入一个全面的遗留数据集，开发一个网络用户界面和网络服务，供客户系统访问所持有的数据。VentDB系统的开发将利用面向服务的架构（SAO）的现有系统组件，该架构适用于地球化学计划的地理信息学的所有数据系统。用户界面将提供交互式查询工具、交互式地图以及数据质量评价和数据分析工具。它将与EarthChem、海洋地球科学数据系统MGDS（包括Ridge 2000和MARGINS 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结合。海底热液泉的化学数据对于研究洋中脊和海底过程、海洋水化学、全球地球化学循环以及喷口生态系统和海底下生物圈至关重要。通过促进对全球热液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。这将是一个主要的工具，以提高我们对地球系统的理解，使研究人员能够整合数据类型和开发新的跨学科的方法来解决科学问题。我们预计这个项目将带来许多新的基本见解和意想不到的结论，这些结论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。开发信息系统，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，先进的可视化工具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，这些数据正在课程中使用，并使地球科学学生对数据处理和解释有了新的认识。研究人员整合各种数据类型的能力得到加强，将导致更好地了解地球和生态系统的发现。

ABSTRACTOCE-0819368Intellectual 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.
