  1. 1. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments

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

    Author : Matthias Benjamin Siewert; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon; soil organic carbon; permafrost; soil; land cover classification; digital soil mapping; machine-learning; ecosystem; mapping; landscape studies; Siberia; Arctic; Physical Geography; naturgeografi;

    Abstract : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. READ MORE

  2. 2. Eurasian Arctic Tectonics: Geology of Severnaya Zemlya (North Kara Terrane) and Relationships to the Timanide Margin of Baltica

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henning Lorenz; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Arctic; Severnaya Zemlya; North Kara Terrane; Baltica; bedrock; geology; tectonics; Timanides; Caledonides; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap;

    Abstract : The North Kara Terrane (NKT), with Severnaya Zemlya as its main outcrop area, constitutes the Palaeozoic and older rocks of the northern part of the Kara Shelf. Potential field data suggest a continuation into the eastern Barents Shelf. READ MORE

  3. 3. Glacial geology and palaeo-ice dynamics of two ice-sheet margins, Taymyr Peninsula, Siberia and Jameson Land, East Greenland

    University dissertation from Quaternary Sciences, Department of Geology, Lund University

    Author : Helena Alexanderson; Lund University.; Lunds universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ice dynamics; Pleistocene; Arctic Siberia; East Greenland; Sedimentology; Physical geography; Sedimentologi; pedology; geomorphology; klimatologi; kartografi; marklära; geomorfologi; cartography; Fysisk geografi; ice-marginal processes; glacial history; climatology;

    Abstract : The North Taymyr ice-marginal zone (NTZ) on the Taymyr Peninsula, Arctic Siberia and the Ugleelv Valley on Jameson Land, East Greenland, have been investigated with the aim of reconstructing the glacial history, including depositional processes and environments. Geomorphological, sedimentological, stratigraphical and remote sensing methods have been combined to give a comprehensive view of developments in the two areas. READ MORE

  4. 4. Carbon Emissions from Western Siberian Inland Waters

    University dissertation from Umeå : Umeå University

    Author : Svetlana Serikova; Umeå universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon; carbon dioxide; methane; carbon emissions; river; lake; inland waters; permafrost; Siberia; Limnology; limnologi;

    Abstract : Inland waters (i.e. rivers, streams, lakes, ponds) emit carbon (C) into the atmosphere. The magnitude of global inland water C emission has been estimated to equal the global ocean C sink, thus making inland waters an important component of the global C cycle. READ MORE

  5. 5. Population fluctuations and life history consequences in the arctic fox

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Magnus Tannerfeldt; Stockholms universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; zoologisk ekologi; Animal Ecology;

    Abstract : In this thesis, I describe and explain drastic population fluctuations in the arctic fox Alopex lagopus (L.). I proceed to examine evolutionary consequences of unpredictable fluctuations in terms of life history strategies. In fluctuating populations, the risks and benefits of different behaviours vary with changes in population density. READ MORE
