Marine and aeromagnetic data in NGDC-720

Developing a good model of Earth's crustal magnetic field requires significant amounts of surface or near-surface data. The National Geophsycial Data Center and co-located World Data Center for Solid Earth Geophysics could not have developed the NGDC-720 model without the support and participation of the following:
