  3. 33. Regulation of carbon dioxide emission from Swedish boreal lakes and the Gulf of Bothnia

    Författare :Grete Algesten; Mats Jansson; Pirkko Kortelainen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical geography and sedimentology; lakes; boreal; Gulf of bothnia; CO2; NEE; DOC; mineralization; sediment; catchment; net heterotrophy; Naturgeografi och sedimentologi; Physical geography; Naturgeografi; naturgeografi; Physical Geography;

    Sammanfattning : The global carbon cycle is subject to intense research, where sources and sinks for greenhouse gases, carbon dioxide in particular, are estimated for various systems and biomes. Lakes have previously been neglected in carbon balance estimations, but have recently been recognized to be significant net sources of CO2. LÄS MER

  4. 34. Diatoms as indicators of Holocene climate and environmental change in northern Sweden

    Författare :Christian Bigler; Ingemar Renberg; Roland Hall; N. John Anderson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical geography and sedimentology; diatoms; Holocene; paleolimnology; climate change; lake sediments; transfer functions; quantitative environmental reconstructions; northern Sweden; Abisko; Naturgeografi och sedimentologi; Physical geography; Naturgeografi; naturgeografi; Physical Geography;

    Sammanfattning : The objective of the thesis was to explore the potential of diatoms (Bacillariophyceae) as indicators of Holocene climate and environmental change in northern Sweden (Abisko region, 68°21'N, 18°49'E). A modern surface-sediment calibration set including 100 lakes was developed and lake-water pH, sedimentary organic content (assessed by loss-on-ignition) and temperature were identified as most powerful environmental variables explaining the variance within the diatom assemblages.

  5. 35. Development of a Detailed Geomorphological Mapping System and GIS Geodatabase in Sweden

    Författare :Marcus Gustavsson; Else Kolstrup; Harry Seijmonsbergen; Ian S. Evans; Uppsala universitet; []
    Nyckelord :Physical geography and sedimentology; Geomorphology; Geomorphological map; GIS; Sweden; Naturgeografi och sedimentologi;

    Sammanfattning : This thesis presents a method for detailed landscape presentation. The method incorporates both fieldwork-based comprehensive geomorphological description and digital data handling and thus contributes in filling the gap between traditional geomorphological mapping and modern geomorphological studies performed in Geographic Information Systems (GIS).
