Data Services in Support of Marine Geoscience Research: Preservation, Synthesis and Access

该项目为共享海洋地质和地球物理数据的设施提供持续支持。用户可以为新的研究项目下载和使用来自全球海洋的数据。软件使科学家、教育工作者和学生能够轻松地探索和可视化海底。地形综合体综合了海底和陆地数据，供研究人员和公众使用。更广泛的影响包括为用户社区举办讲习班和让少数群体服务学院的暑期本科生参与进来。该项目支持补充学科数据服务，重点是保存和获取在全球海洋获得的海洋地质和地球物理数据。海洋地球科学数据系统负责协调收集有关海底和海底以下的学科数据，并提供数据文件和保存服务，以支持数据的出版、发现和再利用。全球多分辨率地形(GMRT)合成是一种多分辨率数字高程模型(DEM)，它将精选的多波束测深数据与其他公开可用的高程数据无缝集成，以按需为跨学科研究人员和公众提供定制地图和高程数据产品。可视化和数据发现工具GeoMapApp(GMA)提供对包括GMRT在内的已发布和社区来源的地学数据集的基于地图的定量访问，并使研究人员能够在补充数据的背景下可视化和分析他们自己的数据。MGDS、GMRT和GeoMapApp的组合数据服务确保海洋地球科学数据是可查找、可访问、可互操作和可重复使用的(FIRE)，每个系统处理的数据管理的互补方面为这些独特的、时空稀疏的观测数据增加了价值。通过该项目公开提供的工具和精选数据收集支持学科和跨学科研究和教育。该项目由海洋科学部的海洋地质和地球物理项目和极地项目办公室的南极项目支持。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。

This project provides continued support for a facility that shares marine geology and geophysics data. Users can download and use data from the global oceans for new research projects. Software allows scientists, educators, and students to easily explore and visualize the seafloor. A topography synthesis integrates seafloor and land data for use by researchers and the public. Broader impacts include workshops to the user community and engagement of summer undergraduate students from Minority Serving Institutions.This project supports complementary disciplinary data services focused on the preservation and access of marine geology and geophysics (MGG) data acquired throughout the global ocean. The Marine Geoscience Data System (MGDS) curates a coherent collection of disciplinary data about the seafloor and subseafloor, and provides data documentation and preservation services that support data publication, discovery and re-use. The Global Multi-Resolution Topography (GMRT) synthesis is a multi-resolution Digital Elevation Model (DEM) that seamlessly integrates curated multibeam bathymetry data with other publicly available elevation data to deliver custom maps and elevation data products on-demand for interdisciplinary researchers and the public. The visualization and data discovery tool GeoMapApp (GMA) provides map-based quantitative access to published and community-sourced geoscience data sets, including GMRT, and empowers researchers to visualize and analyze their own data within the context of complementary data. The combined data services of MGDS, GMRT, and GeoMapApp ensure that marine geoscientific data are Findable, Accessible, Interoperable, and Reusable (FAIR), and the complementary aspects of data stewardship handled by each system adds value to these unique and spatiotemporally sparse observational data. The tools and curated data collections that are made publicly available through this project support disciplinary and transdisciplinary research and education.This project is supported by the Marine Geology and Geophysics program in the Division of Ocean Sciences and the Antarctic program in the Office of Polar Programs.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.
