A proposal for a hull mounted multibeam sonar and subbottom profiler on the icebreaker Oden for marine geoscientific research in the Arctic Ocean
Period: 1/1/07 - 12/31/07
The past 50 years have seen remarkable technological advancements in the field of geophysical seafloor mapping. The development of the multibeam bathymetric sonar represents one major breakthrough and the chirp subbottom profiler another. Multibeam mapping involves the use of many simultaneous ...
Advanced chemical study of microbe-mineral interactions: implications for bacteria-mycorrhiza-tree symbiosis on nutrient cycling in forest soils
Period: 1/1/08 - 12/31/09
Advanced chemical techniques will be used to expand the understanding of the impact and significance of molecular-scale processes, such as biochemically induced weathering caused by exudates from bacteria-fungi-tree interactions, on macro-scale processes, such as nutrient cycling in forest soils ...
Advanced chemical study of microbe-mineral interactions: implications for bacteria-mycorrhiza-tree symbiosis on nutrient cycling in forest soils
Period: 1/1/10 - 12/31/11
Advanced chemical techniques will be used to expand the understanding of the impact and significance of molecular-scale processes, such as biochemically induced weathering caused by exudates from bacteria-fungi-tree interactions, on macro-scale processes, such as nutrient cycling in forest soils ...
Apportionment of natural versus anthropogenic sources of halocarbons depleting Arctic ozone: Novel applications of powerful halocarbon-specific analysis of d37Cl, d81Br and D14C isotopes
Period: 1/1/08 - 12/31/10
Halogenated volatile organic compounds (HVOC) such as CH3Br, CH3Cl and CHBr3 have a mix of natural and anthropogenic sources and stand for a poorly constrained contribution (25-50%?) of halogen-induced ozone depletion in the Arctic atmosphere. Source-diagnostic dual-isotopic fingerprint of these ...
Arctic Alaska & Eurasian Orogens
Period: 1/1/15 - 12/31/18
För flera hundra miljoner år sedan kolliderade urtida kontinenter för att bilda de kända eurasiska bergskedjorna: Uraliska bergskedjan, Kaledoniderna och Timaniderna. Utbredningen av Kaledoniderna och Timaniderna i Eurasien är välkänd, men i norr döljs dessa bergskedjor under havet. Från ...
Arctic Ocean bottom temperatures and bathymetry: Critical parameters for Earth system feedback studies
Period: 1/1/13 - 12/31/17
Detta projekt syftar till att undersöka två kritiska parametrar för studier av klimatets återkopplingsmekanismer i Arktis under den senaste istidscykeln: Arktiska oceanens bottenvattentemperaturer och bottentopografi. Projektet bygger på analyser av befintliga sedimentkärnor som tagits från den ...
Asian monsoon variability and its impact on terrestrial ecosystems in Thailand during the past 25 000 years
Period: 1/1/09 - 12/31/12
Thailand is a key region for a better understanding of the dynamics and impact of the Asian monsoon system: it extends between 5°-20° N, is situated at the boundary between two monsoon sub-systems and in close proximity to the western Pacific Ocean. Thailand has a variety of lakes and wetlands ...
Asian monsoon variability and its impact on terrestrial ecosystems in Thailand during the past 25,000 years
Period: 1/1/09 - 12/31/11
Thailand is a key region for a better understanding of the dynamics and impact of the Asian monsoon system: it extends between 5°-20° N, is situated at the boundary between two monsoon sub-systems and in close proximity to the western Pacific Ocean. Thailand’s lakes form exceptional ...
Asian monsoon variability and its impact on terrestrial ecosystems in Thailand during the past 50 000 years.
Period: 1/1/12 - 12/31/14
Hur påverkas terrestra ekosytem av abrupta förändringar i monsunintensitet? Det asiatiska monsunsystemet är ett av de mest dynamiska klimatsystemen på Jorden och påverkar en region med mer än 60 procent av världens befolkning. Medan sommarmonsunen tillför stora nederbördsmängder, leder ...
