Enrolment in a relevant PhD programme. Basic knowledge of the seismic method.
The course gives in-depth knowledge in geophysical exploration on snow, ice or frozen ground with particular emphasis on seismic surveying, but also includes the basics of geo-radar and electromagnetic surveying and on various physical properties of frozen or partly melted materials characteristic for Polar environments.
The structure of the upper crust in polar areas is poorly known. By geophysical exploration we can reveal properties of the upper few kilometres of the earth. The course starts by introducing the basic principles of pressure (P) and shear (S) waves, and how they are utilized in seismic exploration on snow, ice and floating ice. The similar principles are then presented for geo-radar and electromagnetic surveying. Subsequently is outlined the physical properties of porous (partly and fully frozen) sediments and ice with emphasis on the effect of the soil temperature. The course focuses on training the students in geophysical data acquisition, processing and interpretation. Finally, specific attention is on the use of the seismic method in monitoring of CO2 sequestration, subsurface fluid flow and pressure alterations.
The students should gain insight in the specific challenges related to seismic exploration in polar environments and how this influences on the seismic analyses.
The course extends over ca 5 weeks including compulsory safety training, and is run in combination with AG-335.
Total lecture hours: Ca. 35 hours.
Total seminar hours: 10 hours.
Field exercises: Ca. 1 week.
Compulsory learning activities:
Fieldwork, computer exercises. Pre-course assignment (to be prepared and presented orally).
All compulsory learning activities must be approved in order to sit the exam.
