ITR/IM (EAR) - Collaborative Research: Development of Data Visualization and Query Tools for NAVDAT, Western North American Volcanic and Intrusive Rock Database

该合同将扩展可通过网络访问的北美西部火山和侵入岩数据库（NAVDAT）的数据内容和效用。这些工具将整合地质信息、地球物理和地壳结构数据，使整个北美西部岩浆活动的复杂模式可视化。2001年获得的初始资金用于开发数据库和网络界面，以及填充来自美国西部的火成岩信息。这次更新将完成该地区晚白垩世至全新世火成岩的地球化学数据汇编，并添加来自加拿大西部和墨西哥北部的年龄相当的岩石分析。该公司还将开发下游It工具，包括传统的岩石学工具和基于gis的工具，这些工具可以可视化火成岩活动的时空模式。知识优势地球科学的未来发展需要整合不同的数据集。NAVDAT旨在实现这种整合，将在地球科学的网络基础设施中发挥关键作用。更广泛的影响NAVDAT扩展了研究基础设施，并支持对基础研究和应用工作（如火山灾害缓解和自然资源开发）感兴趣的地球科学家的合作。NAVDAT的发展还将通过跨越地球科学和信息技术学科的活动，涉及博士后、研究生和本科生的教育。这项工作还将涉及与加拿大和墨西哥科学家的国际合作。

EAR-0313319FarmerThis award will expand the data content and utility of a web-accessible Western North America Volcanic and Intrusive Rock Database (NAVDAT). These tools will integrate geologic information with geophysical and crustal structure data to allow visualization of complex patterns in magmatism throughout western North America. Initial funding received in 2001 was used to develop the database and web interface, as well as populate it with igneous rock information from the western U.S. This renewal will complete the compilation of geochemical data from Late Cretaceous to Holocene igneous rocks from the region and add analyses of age-equivalent rocks from western Canada and northern Mexico. It will also develop downstream IT tools including conventional petrologic tools and GIS-based tools that allow visualization of time-space patterns in igneous activity. Intellectual Merits Future progress in geoscience requires the integration of diverse datasets. NAVDAT is aimed at such integration, will play a key role in the cyberinfrastructure for the geosciences.Broader Impacts NAVDAT expands research infrastructure and supports collaboration of geoscientists with interests in both basic research and applied work such as volcanic hazard mitigation and natural resource exploitation. NAVDAT's development will also involve the education of postdoctoral, graduate, and undergraduate students through activities spanning the disciplines of earth science and information technology. The work will also involve international collaboration with scientists from Canada and Mexico.
