Seismic imaging in 3-D holds great potential for improving our understanding of ice sheet structure and dynamics.Conducting 3-D imaging in remote areas is simplified by using lightweight and logistically straightforward sources.We report results hindigyanvishv.com from controlled seismic source tests carried out near the West Antarctic Ice Sheet Divide investigating the characteristics of two types of surface seismic sources, Poulter shots and detonating cord, for use in both 2-D and 3-D seismic surveys on My Mom Dad Is Well Trained Funny Cartoon Dog Gift For Dog Lover Personalized Shirt glaciers.Both source types produced strong basal P-wave and S-wave reflections and multiples recorded in three components.

The Poulter shots had a higher amplitude for low frequencies (50 Hz) relative to the detonating cord.Amplitudes, frequencies, speed of source set-up, and cost all suggested Poulter shots to be the preferred surface source compared to detonating cord for future 2-D and 3-D seismic surveys on glaciers.
