  2. 16. Dynamics of a Risk Regulation Regime : the Case of Head Injuries in Swedish Ice Hockey

    Author : Olov Hemmingsson; Susanna Öhman; Jörgen Sparf; Jens Zinn; Frederic Bouder; Mittuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This thesis explores the risk regulation regime related to head injuries in Swedish ice hockey, primarily by utilizing a corpus linguistic methodology. More specifically, three empirical studies were conducted. READ MORE

  4. 17. Stability of the free-surface problem arising in ice-sheet- and glacier modeling : Numerical investigation and stabilization

    Author : André Löfgren; Josefin Ahlkrona; Fabien Gillet-Chaulet; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ice-sheet modeling; glacier modeling; ice-sheet dynamics; free-surface flow; stability; stabilization; free-surface stabilization algorithm; Numerical Analysis; numerisk analys;

    Abstract : This thesis consists of two papers dealing with a stabilization method for free-surface flows. The method was initially developed to stabilize mantle-convection simulations, but is in this work extended to ice-sheet- and glacier modeling. READ MORE

  5. 18. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions

    Author : Dorothée Vallot; Rickard Pettersson; Veijo Pohjola; Ken Mattsson; Tómas Jóhannesson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryospheric science; glacier modelling; time-lapse imagery; undercutting; sliding inversion; discrete particle model; calving model; subglacial hydrology; sliding law; automatic detection method; calving events size and frequency; ocean interaction; melt water runoff; ice dynamics; ice flow model; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Abstract : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. READ MORE

  6. 19. The mutual interaction between the time-mean atmospheric circulation and continental-scale ice sheets

    Author : Johan Liakka; Johan Nilsson; Johan Kleman; Gerard Roe; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atmospheric stationary waves; Paleo ice sheets; Ice-sheet ablation; Atmosphere-ice sheet modelling; Climatology; Klimatologi; Meteorology; Meteorologi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : 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. READ MORE

  7. 20. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes

    Author : Christian Nohr; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Water and Heat budgets; Deep-water mixing; Internal Wavedrag; Dynamical Sea Ice production; Sea Ice dynamics;

    Abstract : This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. READ MORE
