  1. 1. Paleoglaciology of the Tian Shan and Altai Mountains, Central Asia

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Robin Blomdin; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciology; glacial geomorphological mapping; cosmogenic nuclide dating; Tian Shan; Altai Mountains; Physical Geography; naturgeografi;

    Abstract : The mountain-systems of Central Asia, act as barriers to atmospheric circulation patterns, which in turn impose striking climate gradients across the region. Glaciers are sensitive indicators of climate change and respond to changes in climate gradients over time by advancing during cold and wet periods and receding during warm and dry periods. READ MORE

  2. 2. Speleothems from Warm Climates Holocene Records from the Caribbean and Mediterranean Regions

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Meighan Boyd; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stable isotopes; U-Th dating; trace elements; stalagmite; speleothem; Mid-Holocene; Caribbean; ITCZ; rapid climate change; climate; Eastern Mediterranean; Peloponnese; Santorini; Neolithic; Alepotrypa Cave; Physical Geography; naturgeografi;

    Abstract : This thesis contributes to increased knowledge on Holocene climate and environmental variability from two complex and sparsely studied areas. Using a speleothem from Gasparee Cave, Trinidad, as a paleoclimate archive, the local expression of the 8. READ MORE

  3. 3. Unravelling Sustainability The complex dynamics of emergent environmental governance and management systems at multiple scales

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Lucas Dawson; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Integrated adaptive environmental governance and management; Social-ecological system dynamics; Complex systems; Sustainability transitions; Sustainability strategies; Multi-level governance; Causal loop diagrams; Green Infrastructure; Landscape restoration; Habitat restoration; Biodiversity conservation; Comprehensive planning; Stakeholder participation; System thinking; Water Framework Directive; Sustainable water governance; Collaborative learning; Communities of practice; Knowledge management; naturgeografi; Physical Geography;

    Abstract : This thesis adopts a complex systems approach to investigate the dynamic emergence of sustainable environmental governance and management systems in multiple contexts in Europe. Accelerating rates of environmental degradation across the world have called the legitimacy of previous environmental governance and management arrangements into question. READ MORE

  4. 4. Numerical modeling of groundwater and air flow between compacted bentonite and fractured crystalline rock

    University dissertation from Stockholm : Department of Physical Geography, Stockholm Univeristy

    Author : Benoît Dessirier; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; naturgeografi; Physical Geography; Two-phase flow; porous media; fractured media; compacted bentonite; crystalline rock; numerical modeling; geological disposal;

    Abstract : The geological repository for final storage of spent nuclear fuel, envisioned by the Swedish Nuclear Fuel and Management Company (SKB), relies on several barriers: copper canisters deposited in holes in the floor of underground tunnels in deep bedrock, embedded in a buffer of compacted bentonite. The initially unsaturated buffer would take up water from the surrounding rock mass and swell to seal any potential gap. READ MORE

  5. 5. Comparison of dating methods for paleoglacial reconstruction in Central Asia

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Natacha Gribenski; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciation; Optically stimulated luminescence dating; Cosmogenic nuclide exposure dating; EMCCD camera; Physical Geography; naturgeografi;

    Abstract : Reconstruction of former Central Asian glaciers extents can provide valuable information about past atmospheric circulation variations. These extents, often marked by terminal moraines, need to be chronologically constrained. Cosmogenic nuclide exposure (CNE) dating is widely used to directly date moraines. READ MORE
