  2. 1. Biogeochemical data from SGU : properties and applications

    Author : Kaj Lax; Reijo Salminen; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : 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.

  4. 2. Environmental applications of biogeochemical data from Geological Survey of Sweden

    Author : Kaj Lax; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : The Geological Survey of Sweden, SGU, has carried out geochemical mapping for several decades. In 1983, two regional mapping programmes were initiated, aiming at a nation wide coverage. READ MORE

  5. 3. Characterization of the structure, stratigraphy and CO2 storage potential of the Swedish sector of the Baltic and Hanö Bay basins using seismic reflection methods

    Author : Daniel Sopher; Christopher Juhlin; Alireza Malehmir; Christian Hübscher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Baltic Basin; Hanö Bay Basin; OPAB dataset; Seismic reflection; CO2 storage capacity; Seismic interpretation; Seismic processing; Vectorising; Digitizing; Tornquist Zone; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : An extensive multi-channel seismic dataset acquired between 1970 and 1990 by Oljeprospektering AB (OPAB) has recently been made available by the Geological Survey of Sweden (SGU). This thesis summarizes four papers, which utilize this largely unpublished dataset to improve our understanding of the geology and CO2 storage capacity of the Baltic and Hanö Bay basins in southern Sweden.

  6. 4. A geophysical investigation of carbonate build-ups in the Baltic Basin using reflection seismic and well data

    Author : Tegan Levendal; Christopher Juhlin; Lars Nielsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reflection seismic; Ordovician; Silurian; Carbonate mud mounds; Reefs; Gotland; Sweden; CAES; Seismic interpretation; OPAB dataset; 3D seismic; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : During the Late Ordovician, the region around Gotland was part of a shallow epicratonic basin in the southern subtropics. Low latitudes, relatively warm sea temperatures and the presence of a shallow marine environment promoted algae to flourish and diverse carbonate build-ups such as carbonate mounds and reefs developed on the southern margin of Baltica.

  7. 5. Groundwater vulnerability assessment using process-based models

    Author : Riitta Lindström; Roger Thunvik; Pertti Vakkilainen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Database; Groundwater vulnerability; Hydrogeological environment; Process-based models; Penetration depth; Turnover time; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : The focus of this thesis is on groundwater vulnerability assessment by process-based simulation models and data acquisition for these assessments. A modelling system for intrinsic groundwater vulnerability assessment in water supply areas was developed, consisting of flow- and transport models for the unsaturated zone and the groundwater zone, coupled to a geographical informa-tion system.
