Course requirements:

Enrolment in a PhD programme in biology or other relevant field, and knowledge similar to AB-202 Arctic Marine Biology.

Academic content:

The students will gain insight into the taxonomy, biogeography and ecology of the main benthic species in Svalbard waters and the polar basin North of Svalbard. The course has a special emphasis on hands-on identification of benthos as well as processes important for understanding the Arctic marine ecosystem.

Lectures deal with identification of benthic species, life history and functional traits, trophic interactions and physical forcing. The practical fieldwork will be designed by the teachers, with significant input from students enrolled in AB-821, and implemented into the course. Work during cruises will focus on several research projects that integrate acquired knowledge and skills, and will vary from year to year, targeting specific habitats or ecological processes.

Learning outcomes:

Upon completing the course, the students will:

  • understand biodiversity patterns and ecological interactions characteristic of high Arctic ecosystems
  • have command over the taxonomy, biogeography and ecology of the main benthic species in Svalbard waters and the polar basin north of Svalbard.

In addition, they will be responsible for extended readings and assessment that provide both greater breadth and depth in Arctic benthic ecology across the Arctic.

Upon completing the course, the students will:

  • be able to identify common Arctic marine benthic species
  • understand strengths and weaknesses of common benthic sampling techniques
  • formulate hypotheses, design sampling plans, and be competent at working alone and in collaborative groups
  • display advanced competence in graphical presentation of data, and synthesis of theory and empirical data into a final presentation of research results.

General competences
Upon completing the course, the students will:

  • have acquired practical experience relating field data to scientific contexts
  • apply basic and advanced statistical analyses to data they have collected
  • interpret data to evaluate scientific hypotheses in the context of ecological theory.

The students will also assess benthic systems in Svalbard waters in a pan-Arctic context.

Learning activities:

The course extends over about 6 weeks including compulsory safety training and is run in combination with AB-321. AB-821 runs one more week after the completion of AB-321.

One-week theoretical introduction and preparation of field activities will be followed by a 10-day research cruise. During this cruise, sampling will be conducted in different localities around Svalbard (fjord and off-shelf). The last part of the course (around 3 weeks) will contain 2 weeks of lab exercises focused on species identification and other relevant analysis of the collected material on which a final written report will be submitted.

The last week of the PhD course is dedicated to preparing a scientific report based on the data from the cruise, and may include seminars on data analysis and presentation, and report writing. Depending on the number of PhD students enrolled, this last week may be conducted as home-study (i.e. not required to be in Svalbard), as determined by the instructor.

Total lecture hours: 30 hours.
Laboratory/exercises/seminars: 35 hours.
Scientific cruise: 10 days.

Compulsory learning activities:

Field excursions, laboratory work, scientific writing and one oral presentation.
All compulsory learning activities must be approved in order to sit the exam.


Method Duration
Percentage of final grade
Written exam  5 hours  35%
Practical exam  3 hours  30%
Final project report (written)  35%

All assessments must be passed in order to pass the course.
Each assessment is graded, and subsequently combined into a single grade. Partial grades for each assessment will be available.

Application deadline: 15 April 2023
