  1. 1. Estimation of snow wetness using multi-offset ground penetrating radar towards more accurate estimates of snow water equivalent

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Nils Granlund; Luleå tekniska universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics; Applied Geology; Tillämpad geologi;

    Sammanfattning : Measurements of snow water equivalent (SWE) constitute an important input to hydrological models used to predict snowmelt runoffs. The new generation of such models use distributed snow data, including distribution of SWE, as input, and rely on it for calibration and validation. LÄS MER

  2. 2. Process water geochemistry at the Kiirunavaara iron mine, northern Sweden

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Magnus Westerstrand; Luleå tekniska universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural sciences - Earth sciences; Naturvetenskap - Geovetenskap; Applied Geology; Tillämpad geologi;

    Sammanfattning : Understanding process water characteristics and variations is important for ensuring the quality of mineral processing of iron ore. Large amounts of water are used, and the quality of the water can be crucial for processes such as flotation, agglomeration and balling. LÄS MER

  3. 3. Applications of the DGT technique for measurements of anions and cations in natural waters

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Helene Österlund; Luleå tekniska universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Since the toxicity and mobility of trace metals are related to the metals' speciation, robust methods for trace metal speciation analysis are of great interest. During the last 15 years, hundreds of scientific articles have been published on the development and applications of the diffusive gradients in thin films (DGT) passive sampling technique. LÄS MER

  4. 4. Fractionation of the stable silicon isotopes studied using MC-ICP-MS analytical method developments and applications in geochemistry

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Emma Engström; Luleå tekniska universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : In spite of the high Si abundance in natural systems, expected significant mass-dependent fractionations, and the importance of the element in many areas of the Earth sciences (focusing on e.g. LÄS MER

  5. 5. Biogeochemical data from SGU properties and applications

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Kaj Lax; Luleå tekniska universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Geochemical mapping is a technique that has been used all over the world for a multitude of purposes. The biogeochemical mapping programme conducted by the Geological Survey of Sweden (SGU) is mainly based on stream plant chemistry, which, opposed to mapping based on inorganic stream sediments or soils, is a method that is very uncommon.
