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.

OCE-0726068学术价值：这项研究支持PetDB（海底岩石学数据库）的持续运行和进一步发展。 PetDB是一个非常成功的数字数据库，它对海底火成岩和变质岩的一套综合地球化学和岩石学数据进行存档、管理和在线访问，目的是最大限度地利用这些数据解决最广泛的科学问题。 PetDB彻底改变了火成岩地球化学社区的数据访问方式，并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洋底岩石岩石学数据集;通过增加新的内容并将PetDB的系统架构与拉蒙特-多尔蒂地球观测站地球化学地理信息学（GfG）计划中的其他系统相结合，提高PetDB数据系统对社区的效用，以最大限度地提高其运行效率，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NSF的海洋火成岩岩石学数据的官方档案，它还被广泛用于本科生和研究生教学，从而促进了地球化学数据在地球科学教育中的使用，并通过其成就和经验，伙伴关系和合作为地理信息学的发展做出了重大贡献。
