| Abstract | As part of a hydrogeophyscial study of an esker - a dome shaped groundwater bearing structure - a seismic profile has been acquired using an in-house two component (horizontal and vertical) Microvibe
seismic source with a 48-channel, three component landstreamer. This feature has been imaged in 2D sections using multifold CMP sorting, nmo corrections, migration and finally converted to depth using borehole data. The lithologies of the esker
system including marine mud (silt and clay), sand, gravel, and diamicton, are well characterised by the seismic facies and their shear wave velocities. The technique of imaging using P-wave and S-wave reflection profiling in the near surface follows
the same geophysical techniques used for oil and gas exploration. |

As part of a hydrogeophyscial study of an esker - a dome shaped groundwater bearing structure - a seismic profile has been acquired using an in-house two
component (horizontal and vertical) Microvibe seismic source with a 48-channel, three component landstreamer. This feature has been imaged in 2D sections using multifold CMP sorting, nmo corrections, migration and finally converted to depth using
borehole data. The lithologies of the esker system including marine mud (silt and clay), sand, gravel, and diamicton, are well characterised by the seismic facies and their shear wave velocities. The technique of imaging using P-wave and S-wave
reflection profiling in the near surface follows the same geophysical techniques used for oil and gas exploration. |
