World Data Center for Marine Geology and Geophysics
A web-based global data bank for potential field gravity and magnetic geophysical data. Allows access via a web browser and contains publicly available datasets as well as proprietary data for subscribers.
Catalog of map and data products of aeromagnetic and gravity data coverage of Canada and other international areas, including marine and offshore. Includes research publications regarding geophysical methods and interpretation.
Geomagnetic data from observations, geomagnetic main field charts, magnetotelluric and seismic deep sounding, geomagnetic pulsation and whistlers, paleomagnetic and archaeomagnetic data, geothermal data, seismic and magnetic prospecting, high temperature and high pressure rheological experimental data.
Provides a clearinghouse for observations of the Earth's gravity field, including the first degree spherical harmonic terms which are commonly referred geocenter variations.
The data sets include magnetic anomalies; Bouguer gravity anomalies; isostatic residual gravity anomalies; uranium, thorium, and potassium gamma-ray measurements; and topography with and without bathymetry.
Research and data service activities pertaining to mass transports and related geophysical and climatic processes in specific components of the Earth system, in areas related to the variations in Earth rotation, gravity field and geocenter that are caused by mass transport in the global geophysical fluids.
