The course is a combination of lectures, theoretical, and practical exercises including fieldwork on the sea ice in the Nuuk area. The lectures will address the objectives of the course, and theoretical exercises will be a combination of group work with case studies, colloquiums, and data analyses. The fieldwork will be carried out around Nuuk and samples collected in the field will be analyzed in the laboratory. The data collected are the basis for the individual report.
The course comprises an introduction to the most important abiotic and biotic parameters in sea ice ecology. The course contains five elements 1) Physical and chemical processes in sea ice, 2) Optical conditions of snow and sea ice, 3) Ice algae physiology, biomass, species distribution and production, 4) Bacteria production and survival strategies, 5) Sea ice in a global context.
The theoretical lectures will be supplemented with laboratory exercises and sampling of sea ice in the field. There will be a focus on getting practical experience with work on sea ice, handling of the samples, measuring optical properties, ice algae physiology, biomass, species composition and bacteria production.
The aim of the course is to give the participants
- Insight into and understanding of the most important physical, optical and chemical factors as light, nutrients, salinity, organic and inorganic carbon dynamics, and temperature chances that are relevant for a sea ice ecosystem.
- Abilities and knowledge to discuss the expected changes in these parameters and how they will influence the sea ice ecosystem.
- An understanding of sea ice as an extreme ecosystem, focusing especially on sea ice algae, being both a critical organism for sea ice ecosystems, and a useful model community.
- A detailed knowledge regarding the photosynthesizing sea ice algae and bacteria, which are adapted to this environment.
