  2. 6. Biogenic Halocarbons in Polar Sea Ice

    Author : Anna Granfors; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Volatile biogenic halocarbons; Sea ice; Antarctica; ice-air flux; gases;

    Abstract : Sea ice is to date a rather poorly investigated part of the cycling of volatile halogenated organic compounds, halocarbons. These compounds are natural sources of reactive iodine and bromine to the atmosphere, and are produced in the marine environment. READ MORE

  4. 7. Spaceborne Synthetic Aperture Radar for Sea Ice Observations, Concentration and Dynamics

    Author : Anders Berg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synthetic aperture radar; interferometry; satellite; sea ice dynamics; sea ice monitoring; sea ice concentration;

    Abstract : Spaceborne Synthetic Aperture Radar (SAR) is the primary choice for sea ice monitoring due to its all-weather, day-and-night capability and regular delivery of high resolution images. This thesis presents methods for estimation of sea ice concentration and drift, a multi-sensor study of Baltic Sea ice radar signatures and an interferometric study of landfast sea ice. READ MORE

  5. 8. 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

  7. 10. Subsurface fluxes of mass and energy at the accumulation zone of Lomonosovfonna ice cap, Svalbard

    Author : Sergey Marchenko; Veijo Pohjola; Rickard Pettersson; Carleen Reijmer; Thomas Schuler; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glacier; ice sheet; sea level; runoff; ice; firn; snow; stratigraphy; density; core; radar; thermistor; temperature; preferential water flow; thermal conductivity; water content; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Abstract : Glaciers cover ca 10% of the Earth's land and are found in the high altitudes and latitudes. They are important components of environmental systems due to the multiple feedbacks linking them with the atmosphere, hydrosphere and periglacial landscapes. READ MORE
