  1. 16. Manganese cycling in the Baltic Sea over the last ~8000 years: the influence of redox conditions on mineral formation and burial

    Författare :Conny Lenz; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; sediments; hypoxia; redox conditions; manganese;

    Sammanfattning : The Baltic Sea is one of the largest brackish water bodies in the world and is suffering extensive environmental issues caused by eutrophication and warming climate. A halocline in the water column divides more saline bottom water fed by inflows through the narrow connection with the North Sea from the surface waters and inhibiting exchange of oxygen between the two water masses.

  3. 17. Ocean circulation in the Amundsen Sea, West Antarctica

    Författare :Ola Kalén; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean; currents; icebergs; remote sensing; ocean model;

    Sammanfattning : The increase of mass loss from the Antarctic Ice Sheet is a significant contribution to global sea level rise. The most rapid changes are occurring in the Amundsen Sea area, where the thinning of the floating glaciers is assumed to be driven by the ocean. LÄS MER

  4. 18. 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

  5. 19. Mapping bathymetry : From measurement to applications

    Författare :Benjamin Hell; Martin Jakobsson; Michele Rebesco; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean and coastal mapping; Digital Bathymetric Model; Geographical Information System; Applications of bathymetric data; Baltic Sea; Arctic Ocean; Seafloor morphology; Ocean circulation; Other earth sciences; Övrig geovetenskap; Marine Geoscience; marin geovetenskap;

    Sammanfattning : Surface elevation is likely the most fundamental property of our planet. In contrast to land topography, bathymetry, its underwater equivalent, remains uncertain in many parts of the World ocean. Bathymetry is relevant for a wide range of research topics and for a variety of societal needs. LÄS MER

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

    Författare :André Löfgren; Josefin Ahlkrona; Fabien Gillet-Chaulet; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
