International Programs

World Data Service

We operate a collocated World Service for Geophysics. To learn more, visit the scientific disciplines:

• Bathymetry & Global Relief
• Earth Observations from Space
• Geomagnetic Data & Models
• Marine Geology & Geophysics
• Natural Hazards
• Space Weather & Solar Events

The World Data System is operated by the International Council for Science (ICSU).

International Bathymetric Mapping Programs & Projects

NCEI operates the:

• International Hydrographic Office Data Center for Digital Bathymetry (IHO DCDB)

and is active in multiple international bathymetric mapping projects:

• General Bathymetric Chart of the Oceans (GEBCO) Program
• Regional ocean mapping projects
• Great Lakes Bathymetric Data Rescue Program

GEBCO and the regional bathymetric mapping projects above are sponsored by the Intergovernmental Oceanographic Commission (IOC) and the IHO.

The Great Lakes data rescue program is a collaboration between the National Centers for Environmental Information (NCEI), formerly the National Geophysical Data Center (NGDC), the Canadian Hydrographic Service (CHS), and NOAA's GLERL and NOS.

International Geomagnetic Programs and Projects

NCEI participates in, and distributes data from the:

• International Geomagnetic Reference Field (IGRF) Version 9 & 10 Projects
• International Geomagnetic Observatory Data Exchange Format Project
• World Digital Anomaly Map Project

The above are programs and projects of the International Association of Geomagnetism and Aeronomy (IAGA).

We cooperate with many intergovernmental and international organizations, committees, programs, and projects not listed above. More information on the extensive international collaborations in individual data disciplines is available.
