  1. 1. Magnetic Resonance Sounding (MRS) in groundwater exploration, with applications in Laos and Sweden

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Nils Perttu; Luleå tekniska universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences - Endogenous eartn sciences; geophysics; magnetic resonance sounding MRS ; spin echo; aquifer; groundwater; resistivity; salinity; Gotland; Khorat Plateau; Norrbotten; Geovetenskap - Endogen geovetenskap; Tillämpad geofysik; Applied Geophysics;

    Abstract : Water is essential for all life on the planet, sustaining and ensuring the earth’s ecosystem. Groundwater from a global perspective provides about 50 % of the potable water, 40 % of the industrial water and 20 % of the irrigation water. READ MORE

  2. 2. Characterization of Hydrogeological Media Using Electromagnetic Geophysics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Niklas Linde; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Hydrogeophysics; radio magnetotellurics; ground penetrating radar; electrical resistance tomography; inversion; regularization; geostatistics; electrical anisotropy; fractured rock; Geofysik; NATURAL SCIENCES Physics Other physics Geophysics; NATURVETENSKAP Fysik Övrig fysik Geofysik;

    Abstract : Radio magnetotellurics (RMT), crosshole ground penetrating radar (GPR), and crosshole electrical resistance tomography (ERT) were applied in a range of hydrogeological applications where geophysical data could improve hydrogeological characterization.A profile of RMT data collected over highly resistive granite was used to map subhorizontal fracture zones below 300m depth, as well as a steeply dipping fracture zone, which was also observed on a coinciding seismic reflection profile.

  3. 3. High-Resolution Seismics Methods Applied to Till Covered Hard Rock Environments

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Björn Bergman; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; High-Resolution; Reflection Seismics; Tomography; Nuclear waste repository; Bedrock; Sediments; Geofysik; NATURAL SCIENCES Physics Other physics Geophysics; NATURVETENSKAP Fysik Övrig fysik Geofysik;

    Abstract : Reflection seismic and seismic tomography methods can be used to image the upper kilometer of hard bedrock and the loose unconsolidated sediments covering it. Developments of these two methods and their application, as well as identifying issues concerning their usage, are the main focus of the thesis. READ MORE

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

    University dissertation from Luleå : Luleå tekniska universitet

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

    Abstract : 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. READ MORE

  5. 5. Geophysical targeting of Fe-oxide Cu-Au deposits in the northern fennoscandian sheild

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Alessandro Sandrin; Luleå tekniska universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geophysics; Tillämpad geofysik; Prospekteringsgeofysik; Exploration Geophysics;

    Abstract : In the last decades Fe-Oxide Cu-Au deposits have been discovered and developed in Australia, South America and Canada. This class of mineral deposits is also present in northern Sweden and thus represents a potential target for improving the mineral production of the country. READ MORE
