Course requirements

60 ECTS within general natural science, of which 30 ECTS within the field of geology/geosciences. The applicant must be enrolled in a programme at Bachelor level, or document that the course is approved into the applicant’s current study programme.

The course should be combined with AG-223 Arctic Climate Change (15 ECTS) and the courses are designed to complement each other.

Academic content

This course will begin with a short introduction to the world’s oceans with focus on their geological structure, oceanography, and main sediment types. In the context of global plate tectonics, the formation of the Arctic Ocean and the resulting changes in the ocean circulation will be discussed. The exploration history of the Arctic Ocean and the discovery of its main physiographic features will be reviewed. Particular attention will be given to the role of glaciations in the formations of the geological structure, sediment stratigraphy and morphology of the Svalbard-Barents Sea continental margin. Typical high-latitude glacial marine sedimentary environments, from small basins in front of outlet glaciers, through fjords, continental shelf and slope, to deep-water abyssal plain will form an important part of the course. Case studies from Svalbard fjord-shelf-slope system will be presented to illustrate typical sediment types and stratigraphic sequences characteristic to each sedimentary environment. The contemporary sediment sources, sedimentary processes, and depositional environments in the Arctic, from the coastal zone and fjords to the central Arctic Ocean as well as the role of sea ice in the climate history will be discussed in . Common Quaternary dating methods and proxies used in reconstruction of palaeoceanographic, sedimentological and climatic variations will be examined. Central part of the course is marine field work where the students will learn and practice modern marine geophysical and geological data acquisition methods and techniques. The geophysical data and sediment cores collected in Svalbard fjords and surrounding continental shelf and slope will be analysed in the lab using multiproxy approach. The field activities will be coordinated with the AG-210 to highlight the links between the marine and terrestrial Quaternary landsystems.

Upon completing the course, the students will:

Learning activities

The course extends over a full semester. Initially, students attend two days of compulsory Arctic survival and safety training.

The modular structure of the course ensures tight theory-practice integration focused on key topic on the Arctic marine sedimentology, marine geophysics and seabed mapping, submarine glacial landform and facies associations, micropaleontology, geochronology, and Arctic Ocean paleoceanography/paleoclimate.

The initial lectures and seminars will give the necessary knowledge in preparation for the marine geological-geophysical work at sea. The students will work in small teams to collect geophysical, oceanographic, and sedimentological data in the fjords and surrounding shelf of Svalbard that will be discussed onboard the vessel and further analysed in the labs and seminars later on at UNIS. This work will be summarized in a combined cruise/lab report. Each topical module consists of series of lectures, seminars, and supervised practical laboratory exercises. The knowledge and skills acquired during the lectures, seminars and laboratory exercises will be practiced when writing and presenting an individual term project towards the end of the course.
