  4. 17. Seismic structure of the central Svecofennian lithosphere

    Author : Sebastian Buntin; Alireza Malehmir; Christopher Juhlin; Michał Malinowski; Raymond Durrheim; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wide-angle reflection refraction seismic; near-vertical incidence seismic; Moho; crust-mantle boundary; saucer-shaped sill; BABEL; FENNOLORA; UPPLAND; Fennoscandian Shield; Bergslagen; Uppland Batholith; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : Lithospheric structures in the Fennoscandian Shield in Sweden have been studied by a number of large-scale wide-angle seismic reflection/refraction (WARR) and normal-incidence reflection profiles since the 1960s. Among these were the over 2000 km long Fennoscandian Long Range (FENNOLORA) project in 1979 and the Baltic and Bothnian Echoes from the Lithosphere (BABEL) in 1989, which provided valuable images of the subsurface down to over 60 km depth including the Moho.

  5. 18. Three-component digital-based seismic landstreamer : Methodologies for infrastructure planning applications

    Author : Bojan Brodic; Alireza Malehmir; Christopher Juhlin; André Pugin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; landstreamer; multicomponent seismic; shear-waves; surface-waves; Geophysics with specialization in Solid Earth Physics; Geofysik med inriktning mot fasta jordens fysik;

    Abstract : To support urban infrastructure planning projects, along with various other near-surface applications, a multicomponent landstreamer was developed. The landstreamer was built with broadband (0-800 Hz), three-component (3C) micro-electro-mechanical system (MEMS) sensors. READ MORE

  6. 19. Analysis of Seismic Data Acquired at the Forsmark Site for Storage of Spent Nuclear Fuel, Central Sweden

    Author : Fatemeh Sharifi Brojerdi; Christopher Juhlin; Alireza Malehmir; Bjarne Almqvist; Ramon Carbonell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forsmark site; anisotropy; deformation zone; reflection seismic; shear-wave splitting; fractures and traveltime tomography;

    Abstract : The Forsmark area, the main study area in this thesis, is located about 140 km north of Stockholm, central Sweden. It belongs to the Paleoproterozoic Svecokarelian orogen and contains several major ductile and brittle deformation zones including the Forsmark, Eckarfjärden and Singö zones. READ MORE

  7. 20. Quantifying the Seismic Response of Underground Structures via Seismic Full Waveform Inversion : Experiences from Case Studies and Synthetic Benchmarks

    Author : Fengjiao Zhang; Christopher Juhlin; Ari Tryggvason; Yanghua Wang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; full waveform inversion; waveform tomography; CO2 monitoring; CO2 sequestration; time lapse seismic; Inversion; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : Seismic full waveform inversion (waveform tomography) is a method to reconstruct the underground velocity field in high resolution using seismic data. The method was first introduced during the 1980’s and became computationally feasible during the late 1990’s when the method was implemented in the frequency domain. READ MORE
