  2. 16. Aeolian dunes of central Sweden

    Author : Martin Bernhardson; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aeolian deposits; Inland dune; LiDAR; Digital elevation model; GIS; Luminescence dating; Holocene; Sweden;

    Abstract : In the Swedish inland there are aeolian deposits present, ranging from scattered single dunes to dune fields of more than 10 km2. These dune fields often pass unnoticed since they presently are covered by vegetation. However, they contain a rich palaeoenvironmental archive. READ MORE

  4. 17. Multidisciplinary Near-Surface Investigation of a Quick-Clay Landslide Prone Area in Southwest Sweden

    Author : Silvia Salas Romero; Alireza Malehmir; Ian Snowball; Christopher Juhlin; Laura Valentina Socco; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quick-clay; reflection seismic; landslide; southwest Sweden; borehole logging; physico-chemical properties; hydrogeological modelling; multichannel analysis of surface waves; magnetics; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : Quick-clay landslides are considered one of the most important geohazards in Sweden, Norway, and Canada. The deposits involved are glacial and postglacial clays and silty clays, which are very sensitive to increased stress that may collapse their structure and cause liquefaction. READ MORE

  5. 18. Quaternary paleoceanography of the Arctic Ocean : A study of sediment stratigraphy and physical properties

    Author : Emma Sellén; Martin Jakobsson; Jan Backman; Dorthe Klitgaard-Kristensen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; sedimentology; Quaternary; stratigraphy; physical properties; Earth sciences; Geovetenskap; Quaternary geology; Kvartärgeologi; Sedimentology; Sedimentologi; Marine Geoscience; marin geovetenskap;

    Abstract : A Quaternary perspective on the paleoceanographic evolution of the central Arctic Ocean has been obtained in this PhD thesis by studying sediment cores from all of the Arctic’s major submarine ridges and plateaus. The included cores were mainly recovered during the Healy-Oden Trans-Arctic expedition in 2005 and the Lomonosov Ridge off Greenland expedition in 2007. READ MORE

  6. 19. An integrated study of geological, magnetic and electromagnetic data for mineral exploration in the Jameson Land Basin, central East Greenland

    Author : Anaïs Brethes; Thorkild Maack Rasmussen; Florian Wellmann; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; central East Greenland; Jameson Land Basin; base metal mineralization; geological structures; magnetic data; electromagnetic data; Prospekteringsgeofysik; Exploration Geophysics;

    Abstract : The Jameson Land Basin, located in central East Greenland, initiated in Devonian time with the collapse of the over-thickened Caledonian Orogen. The basin developed during different phases of rifting from the late Paleozoic to the Mesozoic and has accumulated between 16-18 km of sediments. READ MORE

  7. 20. Computational and spatial analyses of rooftops for urban solar energy planning

    Author : Mohammad Aslani; Stefan Seipel; S. Anders Brandt; Julia Åhlén; Alison Jane Heppenstall; Högskolan i Gävle; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Machine learning; Classification; Segmentation; Support vector machines; Instance selection; Rooftop plane segmentation; Photovoltaic panels; Utiliz-able rooftop areas; Geoinformatics; maskininlärning; klassificering; segmentering; stödvektormaskiner; urval av träningsdata; segmentering av takytor; solcellspaneler; utnyttjande av takytor; geoinformatik; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : In cities where land availability is limited, rooftop photovoltaic panels (RPVs) offer high potential for satisfying concentrated urban energy demand by using only rooftop areas. However, accurate estimation of RPVs potential in relation to their spatial distribution is indispensable for successful energy planning. READ MORE
