Aeromagnetic survey of Kansas

Eos, Transactions American Geophysical Union, 1981
An aeromagnetic survey of Kansas, conducted by the Kansas Geological Survey during the past 5 years, has been completed. The total intensity magnetic field contour map, along with spectrally filtered versions, reveals largescale magnetic patterns, which we correlate with basement composition and paleotectonics.A second vertical derivative map clearly ...

Bathymetric and tectonics of Indian Ocean using MAGSAT data [PDF]

The quality of the MAGSAT data was assessed, especially the characterization of spikes. The spectral passbands of significance to geophysical analysis were analyzed, including computations of spectral coherence between nearby repeating satellite tracks ...

A Second Large Subglacial Impact Crater in Northwest Greenland? [PDF]

Following the discovery of the Hiawatha impact crater beneath the northwest margin of the Greenland Ice Sheet, we explored satellite and aerogeophysical data in search of additional such craters.
