Seismic exploration in arctic areas is challenged by complex surface and near-surface characteristics that impact acquisition logistics and data quality. Often, glacial processes are responsible for the present geomorphology. Freezing and thawing introduce seasonal variations. Remote sensing provides an efficient tool to extract information about water features and different types of vegetation. This information can be used for geomorphological modeling of the surface and near surface with the scope to distinguish various glacial landforms of different elastic properties. The result is a GIS database, which contains maps showing the near-surface geology, land-use features, and acquisition risks.
