Course requirements:

Enrolment in a relevant master programme. Students should have basic knowledge of the seismic method.

Academic content:

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.

Learning outcome:

The students should gain insight in the specific challenges related to seismic exploration in polar environments and how this influences on the seismic analyses.

Learning activities:

The course extends over 4 weeks including compulsory safety training, and is run in combination with AG-835.

Total lecture hours: Ca. 35 hours.
Total seminar hours: 10 hours.
Field exercises: Ca. 1 week.

Compulsory learning activities:

Fieldwork, computer exercises.

All compulsory learning activities must be approved in order to sit the exam.

Assessment:

Method Duration
Percentage of final grade
Written report 30%
Written exam 4 hours 70%

All assessments must be passed in order to pass the course. Only the final grade will be reported, based on the weighted average of the grades from the examination parts.
