Sylabus
1. Introduction to the cryosphere (Marek, Jakub) Physics of frozen water • Cryosphere as part of the Earth’s system • The icy biome2. Physics and chemistry of snow (Jakub) 3. Snow ecology (Jakub)4. Glaciers and ice sheets (guest lecturer Jacob Yde, Sogndal University) Formation of glacial ice • Glacier types • Glacier hydrology • History of glaciation • Glaciers as landscape architects5. Glacier ecology I: The supraglacial ecosystem (Marek) Energy and nutrient sources for glacier surfaces • Cryoconite holes • Surface ice • Supraglacial lakes • Real world example: Ice algae and albedo feedback on the Greenland ice sheet6. Glacier ecology II: The subglacial ecosystem (Marek) Energy and nutrient sources for glacier beds • Basal ice • Subglacial sediments • Subglacial lakes • Real world example: The bed of the Antarctic ice sheet as a methane reservoir7. Glacier ecology III: The englacial ecosystem (Marek) Limitations for life within glacial ice • Ice cores as past climate proxies8. Glacier ecology IV: Glacial ecosystems in the warming world (Marek) Transition to proglacial ecosystems • Ecological succession of deglaciated land • Export of organisms and nutrients from glaciers to downstream ecosystems • Real world example: Export of microbial activity from beneath the Greenland ice sheet9. Lake ice (guest lecturer Birgit Sattler, University of Innsbruck)10. Sea ice (Marek)11. Permafrost ecology (Marek) Energy and nutrient sources for permafrost • Permafrost thawing and greenhouse gas release • Real world example: Seasonal change in the microbial community in the active layer of permafrost in Svalbard 12. The future of the cryosphere (Marek, Jakub)
