  1. 1. Ridged sea ice modelling in climate applications

    University dissertation from Department of Meteorology, Stockholm University

    Author : Sebastian Mårtensson; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic ocean; Baltic Sea; sea ice; ice dynamics; numerical modelling; climate; ice deformation; ice compression; physical and biogeochemical interactions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This work aims to increase our understanding of the nature of large scale features of sea ice from a dynamics point of view.Sea ice plays an important part in the exchange of heat and humidity between sea and air and thus is an important component of the climate system. READ MORE

  2. 2. Light conditions in seasonally ice-covered waters within the Baltic Sea region

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences

    Author : Elina Kari; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seasonal sea ice; Fast ice; Drift ice; Phytoplankton spring bloom; Under-ice plume; Turbidity; Suspended particulate matter; Chlorophyll; Coloured dissolved organic matter; Baltic Sea; marin ekologi; Marine Ecology;

    Abstract : Seasonal ice cover is a major driver of seasonality in aquatic ecosystems in the Baltic Sea region. Ice cover influences the underwater light conditions directly by limiting the light transfer and indirectly by modifying the mixing and circulation under the ice. READ MORE

  3. 3. Biogenic Halocarbons in Polar Sea Ice

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences

    Author : Anna Granfors; Göteborgs universitet.; Gothenburg University.; [2014]
    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. 4. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Christian Nohr; Göteborgs universitet.; Gothenburg University.; [2009]
    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

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sergey Marchenko; Uppsala universitet.; [2018]
    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; Earth Science with specialization in Physical Geography; Geovetenskap med inriktning mot naturgeografi;

    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
