  1. 11. Effects of warming on the green alga Cladophora glomerata : Ecological and genetic responses

    Författare :Jenny Zie; Pauline Snoeijs; Mats Grahn; Anna Godhe; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AFLP; Baltic Sea; Cladophora glomerata; climate change; community ecology; genome scan; global warming; selection; Marine Ecology; marin ekologi;

    Sammanfattning : Since the beginning of the 20th century, average global surface temperature has increased ~0.7 °C and the current scenarios predict that it will continue to rise additional 2-4 °C during the 21st century. LÄS MER

  3. 12. Hydrological Transport in Shallow Catchments: : tracer discharge, travel time and water age

    Författare :Sofie Safeyeh Soltani; Vladimir Cvetkovic; Bijan Dargahi; Jan Olof Selroos; Andrea Rinaldo; KTH; []
    Nyckelord :Hydrological transport; travel time; water age; tracer discharge; Lagrangian pathway approach; pathway lengths; numerical modeling; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : This focuses on hydrological transport in shallow catchments with topography-driven flow paths. The thesis gives new insight to kinematic pathway models for estimation of tracer discharge at the catchment outlet. LÄS MER

  4. 13. Simulating Earthquake Rupture and Near-Fault Fracture Response

    Författare :Billy Fälth; Björn Lund; Roland Roberts; Harald Hökmark; Eric Dunham; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : Sweden is presently a low seismicity area where most earthquakes are small and pose no serious threat to constructions. For the long-term perspectives of safety assessments of geological repositories for spent nuclear fuel, however, the effects of large earthquakes have to be considered. LÄS MER

  5. 14. Modelling water and solute flows at land-sea and land-atmosphere interfaces under data limitations

    Författare :Yoshihiro Shibuo; Georgia Destouni; Jerker Jarsjö; Clifford Voss; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Submarine groundwater discharge; unmonitored flows; catchment hydrology; evapotranspiration; bathymetry; GIS; Aral Sea; nuclear waste repository sites; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Sammanfattning : Water and vapour flows from land to sea and the atmosphere are important for water resources, coastal ecosystems and climate. This thesis investigates possible methods for modelling these flows under often encountered unmonitored hydrological conditions and data limitations. LÄS MER

  7. 15. 40Ar/39Ar, AFT and (U-Th)/He thermochronologic implications for the low-temperature geological evolution in SE Sweden

    Författare :Pia Söderlund; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 40Ar-39Ar; Fennoscandian Shield; U-Th He; AFT; geochronology; thermochronology; cooling; uplift;

    Sammanfattning : The Oskarshamn and Forsmark areas in the Fennoscandian Shield, SE Sweden, have been chosen as potential sites for hosting highly radioactive nuclear waste. To evaluate their respective suitability, the geological history of the bedrock in these two areas has been investigated. This study has focused on the thermal evolution, from c. 500 °C to c. LÄS MER
