GEO-3128 Marine geohazards - 5 stp

The course is administrated by

Institutt for geovitenskap

Type of course

This course is available as a single course.

Course contents

The course deals with marine geological processes that can pose a threat to human life and/or installations at sea and onshore. These processes includes topics such as slope stability and submarine slides, fluids in the subsurface (e.g. pockmarks, mud volcanoes, gas hydrates, CO2-storage, blowouts) and tsunamis generated from earthquakes (faults) and submarine slides. Examples from these topics are further explored through practical exercises.

Application deadline

Applicants from Nordic countries: 1 June for the fall semester.

Applicants from outside the Nordic countries: 15 April for the fall semester.

Admission requirements

Bachelor's degree in geology, or a similar degree following a programme of study of at least three years duration, or similar education approved in accordance with the Norwegian Universities Act section 3-4. In addition, specialization in geology worth the equivalent of at least 80 ECTS credits is required. Normally, an average mark of C or better is required at the bachelor's degree level or other programme for basis of admission.

Application code: 9371.

Objective of the course

Knowledge

The student has

detailed knowledge about the generation, propagation and run-up of tsunamis triggered from submarine slides and subduction zone faults.
detailed knowledge of the geotechnical parameters important for the stability of submarine slopes.
understanding of how fluids and fluid migration can affect the submarine surface.

Skills

The student can

calculate the factor of safety for a translational slide on the sea floor.
calculate the arrival time for a propagating tsunami and the amount of amplification of the run-up in a fjord/inlet.
evaluate pore pressure measurements.
use maps, and geological data from borings to evaluate the stability of a submarine slope.
provide an overview of geo-hazards that can be a danger to the production of offshore oil and gas.
understand how the source area of a tsunami can influence the wave characteristics of the propagating tsunami.

General competences

The student can

carry out the most important elements of geological research projects related to marine geo-hazards: understanding literature, make observations, analyze data, and communicate results to fellow students/scientists.
use data and geological knowledge to understand processes.
work independent and in a team.
