Marine Geological & Geophysical
Data Management at NGDC

NGDC organizational diagram

Marine geological and geophysical data at the National Geophysical Data Center are managed by the MGG Division. The National Geophysical Data Center is part of the US Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Environmental Satellite, Data, and Information Service (NESDIS). NGDC is one of three NOAA National Data Centers (NNDC).

NGDC's mission with regard to Marine Geology & Geophysics (MGG) is data management in the broadest sense, playing a role in the nation's research into the environment and providing data to a wide group of users.

NGDC is responsible for stewardship, archival, and dissemination of geological and geophysical data from the global sea floor and lakebeds. Data are compiled from both national and international sources through cooperative programs and exchange agreements, including through the World Data Center system.

Guidelines for Contributing MGG Data

NATIONAL COOPERATIVE ACTIVITIES:

NGDC is the data management lead for US exploration of potential extended continental shelf (ECS) areas, creates high-resolution digital elevation models in support of tsunami inundation studies, stewards NOS data in support of charting and navigation, and is the US National long-term archive for marine geological and geophysical data collected with US public funds.

• Archive for MGG data collected with US Public Funds
• Data Management for the US Extended Continental Shelf Project
• Digital Elevation Model (DEM) Discovery Portal
• NOS Hydrographic Database
• Tsunami Inundation Gridding Project
• goSEABED cooperative project with CU/INSTAAR

INTERNATIONAL COOPERATION:

In addition to operating the World Data Service for Geophysics, NGDC also operates the International Hydrographic Organization Data Center for Digital Bathymetry (IHO DCDB) on behalf of the Member Nations of the International Hydrographic Organization, participates in many international ocean mapping projects, and maintains the international Index to Marine and Lacustrine Geological Samples database on behalf of multiple sample repositories worldwide.

• Ocean Mapping Projects of the IOC/IHO
  
• GAPA Atlas, Eastern Pacific Region
• Great Lakes Data Rescue Project
• IHO Data Center for Digital Bathymetry
• Index to Marine & Lacustrine Geological Samples Database
• Ocean Drilling Program/DSDP parallel data archive
• US-Japan Committee on Natural Resources
• WOCE data assembly center (external link)
• World Data Service for Geophysics, Boulder (formerly WDC for MGG and WDC for GMG)
