NGDC and the collocated World Data Center for Geophysics and Marine Geology, Boulder (WDC GMG), compile, maintain, archive,
and distribute data from extensive databases in coastal and open ocean areas.
Key data types include trackline geophysics (gravity, magnetics, seismic reflection, bathymetry), sediment thickness, and data from ocean drilling and sea floor and lakebed sediment and rock.
NGDC is the National long-term archive for marine geological and geophysical data collected with US public funds. Learn more about mgg activities or the MGG Division.
