Semester of Instruction
Objectives and Content
The course will treat sealevel changes and related processes through ice ages and interglacials and all the way up to the present, and it will also address future changes. This will include a theoretical and practical introduction to studies of past and present changes and a discussion of the causal connections. The primary emphasize will be the development in Scandinavia, but methods and results from other parts of the world will be dealt with as well. The course includes a practical training in the field (coring and sampling) for learning the cause of action for the ¿isolation basin method¿ aiming at determining the altitude and age of past sea-levels. The course will aim at a deeper understanding of the large and rapid sealevel changes that have characterized the Quaternary period including the most important processes that are causing these changes globally and locally. This also include knowledge of the methods that are being used in such studies and the connections to climatic changes and ice sheet fluctuations.
After completion of the course in GEOV223 the students should have attained the necessary skills within the field of sea level changes enabling them to:
- Review the course of the Quaternary sealevel changes (the main trends) that have take place in different parts of the globe.
- Explain the causes for the large regional differences in relative sea- level changes that have been observed.
- Account for the most important processes that have an influence on sea level changes, including isostacy, eustacy, gravimetric attraction (geoide), temperature and salinity.
- Explain the relation between global warming and consequences for future sea level changes.
- Explain the most important methods that are used to study sea level changes in different parts of the world, with a focus on the geological archives.
- Be able to sample, document and interpret geological strata in bogs and lake basins used for reconstructing past sea level changes.
Manage to write a decent report with results from field investigations (coring) of sediment successions in a lake basin that has been isolated from the sea.
The grading scale used is A to F. Grade A is the highest passing grade in the grading scale, grade F is a fail.
