Course requirements:

Enrolment in a relevant PhD programme.

Academic content:

This course reviews the main variables (light regime, temperature, nutrients, salinity & CO2) affecting marine primary production in the Arctic. We focus on how phytoplankton, sea-ice microalgae and macroalgae are adapted (long term adjustments) and acclimatize (short term adjustments) to variations in the light regime (irradiance, its spectral composition and day length), temperature, salinity and CO2 concentration.

Practical work includes taxonomy (microscope, pictures, molecular overview), primary production measurements using fluorescence kinetics to estimate electron transfer rates (Pulse Amplitude Modulated fluorometry), and light absorption and utilization (spectrophotometer, irradiance meters, spectroradiometer).

Learning outcomes:

Students will acquire a deep comprehension of the system ecology and photo-biology of the Arctic micro- and macroalgae and how growth is related to environmental key factors. The combination of complimentary lectures, and field-based practical work will further their understanding of the environmental challenges, especially climate induced differences in time and space. Student-lead project work will enhance skills in experimental design and analysis including the demands and limitations of fieldwork in extreme environments.

Knowledge
Upon completing the course, the students will:
Have an overview of arctic algae eco-physiology in general. Main focus will be to enhance knowledge in processes related to light climate (irradiance, spectral irradiance and day length) and the corresponding photosynthetic activity and growth in micro- and macroalgae. Knowledge about modern optical methods to measure photosynthesis will be part of the practical curriculum.

Skills
Upon completing the course, the students will:
Have an overview of photosynthetic and growth performance of arctic micro- and macro algae. Know how to measure light climate and photosynthesis in the laboratory and in situ.

General competences
Upon completing the course, the students will:
H
ave competence in how key environmental variables alters photosynthesis and growth of arctic micro- and macro algae throughout the year. Hands-on competence in measurements light climate and photosynthesis in the laboratory and in situ.

Learning activities:

The course extends over 4 weeks including compulsory safety training, and is run in combination with AB-323.

The lectures are based on literature on algal photosynthesis, general physiology, ecology, and we also focus on differences between various algal classes and pigment groups (chemo-, bio-optical- and molecular taxonomy). The course also includes laboratory/field exercises in which students study how different algal groups utilize available light for photosynthesis and growth.

Total lecture hours: 30 hours.
Total seminar hours: 8 hours.
Laboratory work: 30 hours.
Excursion: 7 days.

Compulsory learning activities:

Field excursions, laboratory work, one approved report and a presentation on a given topic.
All compulsory learning activities must be approved in order to sit the exam.
