The preservation of and access to scientific research data is a critical aspect of the modern scientific research enterprise that facilitates reproducibility and enables follow-on research to leverage pre-existing data products and results. We live in a data-rich era, but in many scientific disciplines, including the marine geosciences, there are vast gaps in observational data. In addition to scientific reproducibility, the spatial and temporal sparseness of marine geoscience data coupled with the costs of generating data products (from acquisition to processing and synthesis) are strong drivers for preserving and documenting data for future re-use. Although some marine geoscience data produced by scientific researchers are unique and small volume and are therefore considered to be "long-tail", when aggregated into curated collections, they can be transformed into "big data" where the whole is greater than the sum of its parts. The Marine Geoscience Data System (MGDS) was established in 2003 as a trusted marine geoscience data repository that provides free public access to a curated collection of marine geophysical data products and complementary data related to understanding the formation and evolution of the seafloor and sub-seafloor. The system ensures that NSF-funded marine geoscience research data are Findable, Accessible, Interoperable and Reusable (FAIR), and the richness of the MGDS metadata catalog adds value to its data holdings by providing extensive disciplinary information and context that more readily enables data discovery and re-use. MGDS makes available a digital library of more than 80 terabytes of data files, and is designed to serve the needs of its science user community with a focus on (1) facilitating data discovery and access, (2) curating coherent disciplinary data collections that facilitate the creation of global syntheses, (3) ensuring the long-term preservation and stewardship of research data products, and (4) facilitating compliance with data management and sharing obligations. This project is focused on the continued operation of the MGDS to provide ongoing public access to its curated data collections and to evolve the system to support efficient, scalable and sustainable operations. Technical enhancements will include modernizing and optimizing back-end components and the technical stack that drive the data system, as well as optimizing tools and workflows for integrating new data contributions, and streamlining front-end interfaces that enable discovery and access. The planned technical enhancements will yield operational efficiencies with respect to data curation efforts, data storage costs, and system maintenance to ensure that highly valuable observational marine geoscience data collections are maintained and accessible for ongoing access and use.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

科学研究数据的保存和获取是现代科学研究企业的一个重要方面，它有助于再现性，并使后续研究能够利用已有的数据产品和结果。我们生活在一个数据丰富的时代，但在包括海洋地球科学在内的许多科学学科中，观测数据存在巨大差距。 除了科学上的可重复性外，海洋地球科学数据在空间和时间上的稀少性，加上生成数据产品（从获取到处理和合成）的成本，是保存和记录数据以供今后再用的强大驱动力。虽然科学研究人员产生的一些海洋地球科学数据是独特的，数量小，因此被认为是“长尾”数据，但当这些数据汇集成有组织的数据集时，它们可以转化为“大数据”，整体大于部分之和。海洋地球科学数据系统（MGDS）成立于2003年，是一个值得信赖的海洋地球科学数据储存库，为公众提供免费访问精选的海洋地球物理数据产品和与了解海底和海底下的形成和演变有关的补充数据。该系统确保国家科学基金会资助的海洋地球科学研究数据是可查找的，可解释的，可互操作的和可重用的（FAIR），MGDS元数据目录的丰富性通过提供广泛的学科信息和背景，更容易使数据发现和重用增加了其数据库的价值。MGDS提供了一个超过80 TB的数据文件的数字图书馆，旨在满足其科学用户社区的需求，重点是（1）促进数据发现和访问，（2）管理连贯的学科数据收集，促进全球综合的创建，（3）确保研究数据产品的长期保存和管理，以及（4）促进遵守数据管理和共享义务。 该项目的重点是MGDS的持续运营，以提供持续的公众访问其策展数据集，并发展系统以支持高效，可扩展和可持续的运营。 技术改进将包括更新和优化后端组件和驱动数据系统的技术堆栈，优化整合新数据贡献的工具和工作流程，简化能够发现和访问的前端界面。计划中的技术改进将在数据管理工作、数据存储成本和系统维护方面提高运营效率，以确保维护和访问非常有价值的海洋地球科学观测数据集，以供持续访问和使用。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
