Interpretation of AEM Data in Terms of Ice Keels Geometry
A 2-Dimensional Occam inversion technique is applied to a Limited Airborne Electromagnetic (AEM) survey data set in order to verify that the theoretical expectations for ice keel parameter recovery can be met. Additionally, the data are corrected for aircraft altitude. The results showed a datum alt...

Summary: | A 2-Dimensional Occam inversion technique is applied to a Limited Airborne Electromagnetic (AEM) survey data set in order to verify that the theoretical expectations for ice keel parameter recovery can be met. Additionally, the data are corrected for aircraft altitude. The results showed a datum altitude correction can be successfully applied to AEM data. The 2-D inversion of the data was able to verify that ice keel geometry can be recovered from the data however, the method still requires extensive off-line processing.
