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.
MGDS is covered by Thomson Reuters Data Citation Index. MGDS is covered by SCOPUS. The Marine Geoscience Data System (MGDS), part of the Interdisciplinary Earth Data Alliance (IEDA) facility, provides access to data portals for the NSF-supported Ridge 2000, MARGINS, and GeoPRISMS programs, the Antarctic and Southern Ocean Data Synthesis, the Global Multi-Resolution Topography Synthesis, and Seismic Reflection Field Data Portal. These portals were developed and are maintained as a single integrated system, providing free public access to a wide variety of primarily marine geoscience data collected during expeditions throughout the global oceans. In addition to these Data Portals, MGDS also hosts the US Antarctic Program Data Coordination Center (USAP-DCC) which provides tools to help scientists find Antarctic data of interest and satisfy their obligation to share data under the NSF Office of Polar Programs (OPP) data policy.
