PetDB, The Petrological Database of the Ocean Floor Continued Operation

摘要（Lehnert） oce -0726068智力优势：本研究为海底岩石数据库PetDB的持续运行和进一步发展提供了支持。PetDB是一个非常成功的数字数据收集，存档，管理，并使在线访问海底火成岩和变质岩的地球化学和岩石学数据的集成集，目标是最大限度地利用这些数据的最广泛的科学问题的长期效用。PetDB彻底改变了火成岩地球化学界的数据访问方式，极大地提高了地球化学数据的实用性，使研究人员和教育工作者受益。该项目的主要目标是继续为地球科学界提供高质量的海底岩石学数据集；通过增加新的内容，并将PetDB的系统架构与Lamont-Doherty地球观测站地球化学地球信息学（GfG）项目中的其他系统的体系结构保持一致，增强PetDB数据系统对社区的效用，以最大限度地提高其运营效率，包括管理、开发和维护任务。更广泛的影响：PetDB为广大受众提供全球可访问的数据汇编，支持地球和海洋科学许多领域的研究和教育。该数据库不仅作为美国国家科学基金会海洋火成岩岩石学数据的官方档案，还广泛应用于本科和研究生教学，从而促进了地球化学数据在地球科学教育中的应用，并通过其成果和经验，伙伴关系和合作，为地球信息学的发展做出了重大贡献。

ABSTRACT (Lehnert)OCE-0726068Intellectual Merit: This research supports the continued operation and further development of PetDB, the Petrological Database of the Ocean Floor. PetDB is a highly successful digital data collection that archives, manages, and makes accessible online an integrated set of geochemical and petrological data for ocean floor igneous and metamorphic rocks with the objective to maximize the long-term utility of these data for the widest range of scientific problems. PetDB has revolutionized data access for the igneous geochemistry community and dramatically advanced the utility of geochemical data to the benefit of researchers and educators. The primary objectives of the project are to continue serving the geoscience community the high-quality petrological dataset of ocean floor rocks; enhance the utility of the PetDB data system to the community by adding new content and aligning PetDB's system architecture with that of the other systems in the Geoinformatics for Geochemistry (GfG) program at the Lamont-Doherty Earth Observatory to maximize the efficiency of its operation, including management, development, and maintenance tasks. Broader Impacts: PetDB provides access to globally accessible data compilations for broad audiences, supporting research and education in many fields of the Earth and Ocean Sciences. The database not only serves as the official archive of marine igneous petrology data for NSF, it has also been used extensively in undergraduate and graduate teaching, thereby advancing the use of geochemical data in Geoscience education, and has contributed significantly to the development of Geoinformatics through its achievements and experiences, partnerships and collaboration.
