Marine Geoscience Data System 2020: Optimizing Established Data Infrastructure for the Future

保存和获取科学研究数据是现代科学研究企业的一个关键方面，它促进了可再现性，并使后续研究能够利用先前存在的数据产品和结果。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。除了科学上的再现性，海洋地球科学数据的空间和时间稀疏性以及产生数据产品的成本(从获取到处理和合成)是保存和记录数据以供未来重复使用的强大驱动因素。尽管科学研究人员产生的一些海洋地球科学数据独特、体积小，因此被认为是“长尾”的，但当集合成精选集合时，它们可以转化为整体大于部分之和的“大数据”。海洋地球科学数据系统成立于2003年，是一个值得信赖的海洋地球科学数据储存库，供公众免费查阅与了解海底和次海底的形成和演化有关的海洋地球物理数据产品和补充数据。该系统确保由国家科学基金会资助的海洋地球科学研究数据是可查找、可访问、可互操作和可重复使用的(公平)，MGDS元数据目录的丰富通过提供广泛的学科信息和更容易实现数据发现和重复使用的背景，增加了其数据持有的价值。MGDS提供了一个超过80太字节数据文件的数字图书馆，旨在满足其科学用户群体的需求，重点是(1)促进数据发现和访问，(2)管理协调一致的学科数据收集，以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。该项目的重点是继续运作全球监测系统，为公众提供持续查阅其经过管理的数据收集的机会，并发展系统以支持高效、可扩展和可持续的运作。技术改进将包括对驱动数据系统的后端组件和技术堆栈进行现代化和优化，以及优化用于整合新数据贡献的工具和工作流程，并简化支持发现和访问的前端接口。计划中的技术增强将在数据管理工作、数据存储成本和系统维护方面产生运营效率，以确保维护和访问高价值的观测海洋地球科学数据集合，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智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
