1. 11. CO2 storage in deep saline aquifers : Models for geological heterogeneity and large domains

   Författare :Liang Tian; Auli Niemi; Fritjof Fagerlund; Simon Mathias; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CO2; Carbon Capture Storage; Storage Capacity; Injectivity; Monte Carlo; Gaussian; Permeability; Upscaling; 二氧化碳; 地質封存; 高斯仿真; 滲透係數; 非均質性; 升尺度; 存儲效能; 場地模擬; 不確定性; 壓力累積;

   Sammanfattning : This work presents model development and model analyses of CO2 storage in deep saline aquifers. The goal has been two-fold, firstly to develop models and address the system behaviour under geological heterogeneity, second to tackle the issues related to problem scale as modelling of the CO2 storage systems can become prohibitively complex when large systems are considered.

3. 12. Uncertain Futures : Adaptive capacities to climate variability and change in the Lake Victoria Basin

   Författare :Sara Gabrielsson; LUCSUS; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adaptive capacities; climate vulnerability; collective action; Lake Victoria Basin; smallholder farmers; sustainable adaptation; sustainability science.;

   Sammanfattning : The Lake Victoria basin (LVB) in East Africa can be considered a climate change hotspot because of its large rural population dependent on rain-fed farming. Drawing on extensive fieldwork (2007-2011) in rural communities along the shores of Lake Victoria in Kenya and Tanzania, I explore adaptive capacities to climate variability and change and discuss how they interrelate in situ.

4. 13. New constraints on paleoreconstructions through geochronology of mafic dyke swarms in North Atlantic Craton

   Författare :Mimmi Nilsson; Berggrundsgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; baddeleyit; U-Pb; geokronologi; large igneous province; mantelplym; superkontinent; paleorekonstruktion; North Atlantic craton; baddeleyite; Large Igneous Province; Mantle plume; supercontinent; paleoreconstruction; U-Pb; geochronology; North Atlantic craton;

   Sammanfattning : Earth history is punctuated by a series of events of supercontinent amalgamation and break-up. Fragments of old continents display rifted margins and orogenic sutures that testify their involvement in supercontinent cycles. LÄS MER

7. 15. Shallow water carbonate basin of the Zanzibar channel, Tanzania

   Författare :Yohanna W Shaghude; Birger Larsen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allmän och historisk geologi; General and Historical Geology;

   Sammanfattning : The shallow water carbonate basin of the Zanzibar channel, Tanzania, has been investigated. This study discusses and describes the sea bottom topographic features, sediment composition, major characteristics of sediment distribution, provenance of sediments, and the depositional settings of the sediments .
