The course gives in-depth knowledge in seismic exploration on snow, ice or frozen ground. Particular attention is on seismic acquisition, processing and on the seismic properties of frozen or partly melted materials, including gas hydrates, characteristic for Polar environments.
The structure of the upper crust in polar areas is still relatively poorly known. By seismic exploration the sound properties of the upper few kilometres of the earth is revealed. The course starts by introducing the basic principles behind pressure (P) and shear (S) waves, and how they are utilized in seismic exploration on snow, ice and in open sea in the vicinity of sea ice. Then is outlined the physical properties and elastic wave propagation in porous (partly and fully frozen) sediments and ice, with emphasis on the effect of the soil temperature. Furthermore, the foundation and seismic properties of gas hydrates are discussed. The course follows by outlining the main procedures in seismic processing and interpretation. Finally, specific attention is paid on the use of the seismic method in monitoring of CO2 sequestration, subsurface fluid flow and pressure alterations.
