16. The mutual interaction between the time-mean atmospheric circulation and continental-scale ice sheets
Sammanfattning : Geomorphological evidence of glaciations exist for the Last Glacial Maximum (about 20 kyr ago). At this time, both North America and Eurasia were covered by extensive ice sheets which are both absent today. LÄS MER
17. Proterozoic crustal growth along the Archaean continental margin in the Luleå area, northern Sweden
Sammanfattning : .... LÄS MER
18. Silicic Magma Genesis in Basalt-dominated Oceanic Settings : Examples from Iceland and the Canary Islands
Sammanfattning : The origin of silicic magma in basalt-dominated oceanic settings is fundamental to our understanding of magmatic processes and formation of the earliest continental crust. Particularly significant is magma-crust interaction that can modify the composition of magma and the dynamics of volcanism. LÄS MER
19. Carbon Dynamics in Northern Marginal Seas
Sammanfattning : The marginal seas have, despite their relatively small area, an important role in the global carbon cycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. LÄS MER
20. Microbial life deep underground : From anaerobic cultures to reconstructed genomes
Sammanfattning : The deep biosphere refers to the vast ecosystem of life beneath the Earth’s surface, residing in the fractured bedrock and pores of rocks, largely isolated from solar energy. These fractures enclose an important reservoir of groundwater that contains microorganisms active in processes such as the uptake of inorganic carbon, sulfur cycling, or the degradation of organic matter.
