    Evolution of Stresses Over Conjugate Faults in Hjalli‐Ölfus, South Iceland 
    Mozhikunnath Parameswaran, Revathy; Bjarnason, Ingi Þorleifur; Þorbjarnardóttir, Bergþóra Sólveig (American Geophysical Union (AGU), 2023-03-14)
    Hjalli-Ölfus is the westernmost segment of the east-west transform South Iceland Seismic Zone (SISZ), which is the eastward extension of the ∼ENE-trending transtensional Reykjanes Peninsula (RP). Historically, the area has shown an interactive behavior ...

    A Framework to Study Mixing Processes in the Marine Boundary Layer Using Water Vapor Isotope Measurements 
    Benetti, Marion; Lacour, Jean-Lionel; Sveinbjörnsdóttir, Árný; Aloisi, G.; Reverdin, G.; Risi, C.; Peters, A. J.; Steen‐Larsen, H. C. (American Geophysical Union (AGU), 2018-03-10)
    We propose a framework using water vapor isotopes to study mixing processes in the marine boundary layer (MBL) during quiescent conditions, where we expect evaporation to contribute to the moisture budget. This framework complements the existing models, ...

    Hydroclimate in the Pamirs Was Driven by Changes in Precipitation‐Evaporation Seasonality Since the Last Glacial Period 
    Aichner, Bernhard; Makhmudov, Zafar; Rajabov, Ilhomjon; Zhang, Qiong; Pausata, Francesco S. R.; Werner, Martin; Heinecke, Liv; Kuessner, Marie L.; Feakins, Sarah J.; Sachse, Dirk; Mischke, Steffen (American Geophysical Union (AGU), 2019-12-03)
    The Central Asian Pamir Mountains (Pamirs) are a high-altitude region sensitive to climatic change, with only few paleoclimatic records available. To examine the glacial-interglacial hydrological changes in the region, we analyzed the geochemical ...

    Initial results from the ICEMELT Experiment: Body-wave delay times and shear-wave splitting across Iceland 
    Bjarnason, Ingi Þorleifur; Wolfe, Cecily J.; Solomon, Sean C.; Guðmundsson, Gunnar (Wiley-Blackwell, 1996-03-01)
    We present results from the first stage of the ICEMELT broadband seismometer experiment designed to determine upper mantle structure beneath Iceland, a hotspot located on the Mid-Atlantic Ridge. Relative delays of teleseismic body waves across Iceland ...

    Lava field evolution and emplacement dynamics of the 2014–2015 basaltic fissure eruption at Holuhraun, Iceland 
    Pedersen, Gro; Höskuldsson, Ármann; Dürig, Tobias; Thordarson, Thorvaldur; Jonsdottir, Ingibjorg; Riishus, M. S.; Óskarsson, B.V.; Dumont, Stéphanie; Magnússon, Eyjólfur; Gudmundsson, Magnus Tumi; Sigmundsson, Freysteinn; Drouin, V.J.P.B.; Gallagher, C.; Askew, R.; Gudnason, J.; Moreland, William; Nikkola, P.; Reynolds, Hannah Iona; Schmith, Johanne (Elsevier BV, 2017-06)
    The 6-month long eruption at Holuhraun (August 2014–February 2015) in the Bárðarbunga-Veiðivötn volcanic system was the largest effusive eruption in Iceland since the 1783–1784 CE Laki eruption. The lava flow field covered ~84 km2 and has an estimated ...

    Quantifying the Effect of Wind on Volcanic Plumes: Implications for Plume Modeling 
    Dürig, Tobias; Guðmundsson, Magnús T.; Dioguardi, Fabio; Schmidt, Louise Steffensen (American Geophysical Union (AGU), 2023-01-13)
    The considerable effects that wind can have on estimates of mass eruption rates (MERs) in explosive eruptions based on volcanic plume height are well known but difficult to quantify rigorously. Many explicitly wind-affected plume models have the ...

    Reinterpretation of the RRISP-77 Iceland shear-wave profiles 
    Menke, William; Brandsdóttir, Bryndís; Einarsson, Páll; Bjarnason, Ingi Þorleifur (Oxford University Press (OUP), 1996-07)
    Two shear-wave profiles, E and G, collected during the 1977 Reykjanes Ridge Iceland Seismic Experiment have played an important role in models of the Icelandic crust. They were originally interpreted as indicating very low shear-wave velocities and ...
