Marine Geoscience Data System

The Marine Geoscience Data System (MGDS) is a trusted 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. Developed and operated by domain scientists and technical specialists with deep knowledge about the creation, analysis and scientific interpretation of marine geoscience data, the system makes available a digital library of data files described by a rich curated metadata catalog. MGDS provides tools and services for the discovery and download of data collected throughout the global oceans. Primary data types are geophysical field data including active source seismic data, potential field, bathymetry, sidescan sonar, near-bottom imagery, other seafloor senor data as well as a diverse array of processed data and interpreted data products (e.g. seismic interpretations, microseismicity catalogs, geologic maps and interpretations, photomosaics and visualizations). Our data resources support scientists working broadly on solid earth science problems ranging from mid-ocean ridge, subduction zone and hotspot processes, to geohazards, continental margin evolution, sediment transport at glaciated and unglaciated margins.

海洋地球科学数据系统（MGDS）是一个备受信赖的数据存储库，它向公众免费提供精心整理的海洋地球物理数据产品和与之相关的数据，这些数据有助于理解海底及海底以下的形成与演化过程。该系统由对海洋地球科学数据的创建、分析及科学解释拥有深厚知识的领域科学家和技术专家开发和运营，提供了一个由丰富编目元数据目录描述的数字图书馆。MGDS为全球海洋中收集的数据的发现与下载提供了工具和服务。主要数据类型包括地球物理场数据，例如主动源地震数据、势场数据、水深数据、侧扫声呐、近底影像、其他海底传感器数据，以及一系列处理数据和解释数据产品（例如地震解释、微地震目录、地质图及其解释、影像拼合和可视化）。我们的数据资源支持广泛从事固体地球科学研究的科学家，研究范围涵盖从海脊、俯冲带和热点过程到地质灾害、大陆边缘演化、冰川和非冰川边缘的沉积物运输等多个领域。
