Light Climate and Primary Productivity in the Arctic


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. 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. 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).
