Description

This data set contains gravity measurements, including acceleration data in three orthogonal directions, from the Sander Geophysics AIRGrav airborne gravity system. Gravity data include latitude and Eotvos-corrected values, as well as free air correction at various along-flight-line time filtering scales. The data were collected as part of Operation IceBridge funded campaigns.
