Course requirements:

Enrolment in a relevant PhD programme. Students with relevant PhD theses will be given preference.

Academic content:

This research-based hands-on course gives students both theoretical and practical insight to Arctic sea ice ecosystems, as well as training in scientific thinking and writing. The course focuses on the lower trophic levels and the coupling between sympagic (= ice assicoated), pelagic and behthic compartments in ice covered seas. Furthermore, the course stimulates to own creative and critical thinking. We ask the students to design their own research questions for the scientific report to be written based upon the samples and data collected during the week-long field excursion with the possibility to also include earlier course data. The scientific report shall be written as a scientific paper. Introduction to physical properties of light, snow, sea ice and hydrography will be given, to better understand the physical constraints and drivers for structuring Arctic sea ice communities. Mechanisms regulating the timing of key biological processes such as the ice algal and phytoplankton blooms and secondary production will be emphasized as well as sea ice biodiversity, and the trophic coupling and carbon flux between sea ice (=sympagic), pelagic and benthic ecosystems.

In 2023, landfast sea ice ecosystems in Spitsbergen will be studied and run in parallel with ongoing research projects on sea ice ecosystems. Transportation will be conducted using snowmobiles. Those without a driving license will travel as passengers. Be aware that in 2023 there will be an Easter break from 5th to 10th April 2023.

Learning outcomes:

Knowledge
Upon completing the course, the students will have:

  • knowledge on species diversity and community composition in sea ice dominated ecosystems in the Arctic
  • extensive knowledge on important biological processes in sea ice ecosystems (colonization, timing of algal blooms, succession, trophic interactions and carbon flux), and general knowledge on physical properties of light, snow, sea ice (formation, age, structure etc.) and hydrography
  • in-depth understanding of which abiotic and biotic drivers that structure these unique sea ice ecosystems, and the linkages between the sea ice (sympagic), pelagic and benthic compartments.

Skills
Upon completing the course, the students will have:

  • the ability to species determine common protists, meiofauna and meso- and macrofauna living within and in close association with sea ice in the high Arctic
  • practical skills in operating various state-of-the art field-devices for collecting physical and biological data in sea ice covered environments
  • competence to plan and carry out field studies under sometimes challenging Arctic conditions
  • the ability to discuss scientific questions related to sea ice ecosystems
  • improved competence in how to design and write a scientific paper.

General competences
Upon completing the course, the students will have:

  • the ability to search for, critically read and extract relevant information from scientific literature
  • competence in design and implementation of research tasks
  • improved written and oral skills based on assignments given during the course
  • experience in problem solving
  • team work experience, including leading and organizing group work
  • experience in safety standards related to work in harsh Arctic environments, including safe snow scooter driving on land an on sea ice.

Learning activities:

The course extends over ca 6 weeks, and is run in combination with AB-330.

The course will start with a theoretical introduction and safety training (5–9 days) followed by extensive sampling activities on sea ice during a week-long field excursion, where PhD students are expected to take an active role as group leaders for 3-4 students. The samples will be analysed partly in field and partly back at UNIS in the laboratory. The data produced from field and lab work will provide the basis for the written scientific report, which will be the main focus for AB-830 students the last week of the course. The PhD students are allowed to work in pairs and are asked to design relevant research questions, based on the data available, for their scientific report which will be written as a scientific paper. Regular seminars will be arranged for discussing selected papers ans the field results, which will stimulate to find the most appropriate data analyses and to draw conclusions.

Total lecture hours: 15 hours.
Laboratory exercises / seminars: 20 hours.
Excursion: Ca. 7 days.
Data analysis and presentations: 10 hours.

Compulsory learning activities:

Field excursions, laboratory work and technical written reports from these practical activities.
All compulsory learning activities must be approved in order to sit the exam.

Assessment:

Method Duration
Percentage of final grade
Written exam 40%
Written scientific report + presentation 60%

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 October 2022
