  2. 1. Advances in time-domain induced polarization monitoring with application on chlorinated solvents contamination : Towards scalable real-time geophysical monitoring

    Author : Aristeidis Nivorlis; Teknisk geologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geoelectrical monitoring; Chlorinated solvents; geophysics; Electrical resistivity tomography ERT ; Contaminated soil; contamination remediation geophysics;

    Abstract : Environmental pollution is a significant concern for scientists, practitioners, authorities and the society. Among the various pollutants, chlorinated solvents pose a considerable risk to our groundwater resources. READ MORE

  4. 2. Controlled Source Radiomagnetotelluric (CSRMT) Applications in Environmental and Resource Exploration

    Author : Nazli Ismail; Laust Pedersen; Bulent Tezkan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetotelluric; radio magnetotelluric; controlled-source tensor magnetotelluric; plane wave; near surface geophysics; sediment; fracture zone; inversion; forward modelling; near field effect; two-dimensional model; three-dimensional model; resolution; Geophysics; Geofysik; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys; Hydrology; hydrologi; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : An integrated use of radio magnetotelluric (RMT) and controlled source tensor magnetotelluric (CSTMT) measurements, the so-called CSRMT method, has been employed in environmental and resource exploration studies. A number of case histories, including a groundwater investigation in glacial deposits, a study of fracture zones for geotechnical purposes and a mining exploration study of a copper deposit, are presented in this thesis in order to illustrate the usefulness and capability of the CSRMT method.

  5. 3. Plane wave electromagnetic measurements for imaging fracture zones

    Author : Lena Persson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Electromagnetic Measurements Fracture Zones; Geofysik; Geophysics; Geofysik; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : Electromagnetic fields from distant radio transmitters interact with the resistivity structures in the earth. They can be regarded as plane-wave fields since their penetration depth is much smaller than their wavelength. READ MORE

  6. 4. Environmental and hydrogeological geophysics with applications in Thailand, Laos, and Sweden

    Author : Kamhaeng Wattanasen; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geophysics; Tillämpad geofysik;

    Abstract : This thesis presents applications of geophysical methods in the fields of environment and hydrogeology. In relation to environmental problems, two different geophysical surveys have been carried out; one to study an arsenic contaminated area in the southern Thailand (paper I) and a second to locate shallow faults in Quaternary sediments in an area around the Ongkharak Nuclear Research Centre, central Thailand (paper II).

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

    Author : Nils Perttu; Jean Roy; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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
