    The 2014-2015 lava flow field at Holuhraun: Deriving physical properties of the lava using multi remote sensing techniques and datasets 
    Aufaristama, Muhammad (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2020-04-29)
    The purpose of this thesis is to employ remote sensing to study lava flow products during the 2014-2015 eruption at Holuhraun, Iceland. Multimodal remote sensing techniques and datasets were applied and developed for three study themes (1) deriving ...

    From partial melting to lava emplacement: the petrogenesis of some Icelandic basalts 
    Nikkola, Paavo (Faculty of Science, University of Helsinki; Faculty of Earth Sciences, University of Iceland, 2020-03-20)
    This thesis provides insights into the petrogenesis of Iceland basalts via three subprojects. The first uses olivine macrocrysts as a proxy for mantle melting conditions below Iceland, the second utilizes petrological thermobarometry to resolve the ...

    Geochemistry of supercritical fluids in active geothermal systems 
    Heřmanská, Matylda (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2020-03)
    Supercritical fluids have been reported from both rift and subduction-related geothermal systems. They typically form in the vicinity of magmatic intrusions at the roots of geothermal systems upon conductive heating and boiling of the subcritical ...

    High‐Temperature Deformation Behavior of Synthetic Polycrystalline Magnetite 
    Till, Jessica L; Rybacki, E.; Morales, L.F.G.; Naumann, M. (American Geophysical Union (AGU), 2019-03)
    We performed a series of deformation experiments on synthetic magnetite aggregates to characterize the high‐temperature rheological behavior of this mineral under nominally dry and hydrous conditions. Grain growth laws for magnetite were additionally ...

    A luminescence-based chronology for the Harletz loess sequence, Bulgaria 
    Lomax, Johanna; Fuchs, Markus; Antoine, Pierre; Rousseau, Denis-Didier; Lagroix, France; Hatté, Christine; Taylor, Samuel N.; Till, Jessica L; Debret, Maxime; Moine, Olivier; Jordanova, Diana (Wiley, 2018-10-08)
    The Harletz loess‐palaeosol sequence is located in northwestern Bulgaria and represents an important link between well‐studied loess sequences in eastern Romania and further sites to the west of the Carpathians (e.g. Serbia and Hungary). The aim of ...

    Message in a stainless steel bottle thrown into deep geological time 
    Lewandowski, M.; Kusiak, M.A.; Michalczyk, Ł.; Szmigiel, D.; Sledziewska-Gojska, E.; Barzycka, B.; Wawrzyniak, T.; Luks, B.; Thordarson, Thorvaldur; Wilde, S.A.; Höskuldsson, Ármann (Elsevier BV, 2017-12)
    In the 60th year after the placing of the corner stone under the Polish Polar Station at Hornsund (PPSH; Spitsbergen, Svalbard, Norway), a new capsule has been laid down in the vicinity of the PPSH. It is made of stainless steel, and includes five ...

    Past dynamics of a marine-terminating glacier in lower Borgarfjörður, west Iceland – Analyses of glaciotectonic sediments and landforms 
    Sigfúsdóttir, Thorbjörg (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2019-11)
    Large and complete sections through glacial landforms formed in subaqueous environments are rare, impeding our knowledge of their internal composition and the processes responsible for their formation. Following the last deglaciation of the Icelandic ...

    Scalable Data Analysis in High Performance Computing 
    Götz, Markus (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2017-12-05)
    Á síðastliðnum áratug hefur orðið mikil aukning í framleiðslu og geymslu gagna í iðnaði sem og rannsóknum. Þrátt fyrir að gagnagreining sé ekki ný af nálinni, stendur hún frammi fyrir þeirri áskorun að ráða við síaukið magn, bandvídd og flækjustig ...
