    2021–2023 Unrest and Geodetic Observations at Askja Volcano, Iceland 
    Parks, Michelle M.; Sigmundsson, Freysteinn; Drouin, Vincent; Hreinsdóttir, Sigrún; Hooper, Andrew; Yang, Yilin; Ófeigsson, Benedikt G.; Sturkell, Erik; Hjartardóttir, Ásta R.; Grapenthin, Ronni; Geirsson, Halldór; Trasatti, Elisa; Barsotti, Sara; Pedersen, Rikke; Einarsson, Páll; Óladóttir, Bergrún A.; Friðriksdóttir, Hildur M. (2024-02-28)
    Unrest began in July 2021 at Askja volcano in the Northern Volcanic Zone (NVZ) of Iceland. Its most recent eruption, in 1961, was predominantly effusive and produced ∼0.1 km3 lava field. The last plinian eruption at Askja occurred in 1875. Geodetic ...

    Calmness of Linear Constraint Systems under Structured Perturbations with an Application to the Path-Following Scheme 
    Garcia, Carlos Argaez; Cánovas, M. J.; Parra, J. (2021-07-14)
    We are concerned with finite linear constraint systems in a parametric framework where the right-hand side is an affine function of the perturbation parameter. Such structured perturbations provide a unified framework for different parametric models ...

    Chlorine isotope ratios record magmatic brine assimilation during rhyolite genesis 
    Ranta, Eemu Johannes; Halldórsson, Sæmundur Ari; Barnes, J. D.; Jónasson, Kristján; Stefánsson, Andri (2021-01-13)
    Magmatic volatile phases within crustal silicic magma domains influence key volcanic processes such as the build up to eruptions and formation of magmatic-hydrothermal ore deposits. However, the extent and nature of fluid-melt interaction in such ...

    Geomorphology and surficial geology of the Femmilsjøen area, northern Spitsbergen 
    Allaart, Lis; Schomacker, Anders; Håkansson, Lena M.; Farnsworth, Wesley Randall; Brynjólfsson, Skafti; Grumstad, Andreas; Kjellman, Sofia E. (2021-06-01)
    Climate change is amplified in the Arctic, and establishing baseline data for its current character is important. Here we present a map of the geomorphology of the Femmilsjøen area, Spitsbergen, northern Svalbard. The regional physiography is characterised ...

    Glacial history of the Åsgardfonna Ice Cap, NE Spitsbergen, since the last glaciation 
    Allaart, Lis; Schomacker, Anders; Larsen, Nicolaj K.; Nørmark, Egon; Rydningen, Tom Arne; Farnsworth, Wesley Randall; Retelle, Michael; Brynjólfsson, Skafti; Forwick, Matthias; Kjellman, Sofia E. (2021-01-01)
    The response of glaciers and ice caps to past climate change provides important insight into how they will react to ongoing and future global warming. In Svalbard, the Holocene glacial history has been studied for many cirque and valley glaciers. ...

    Pseudomonas syringae on plants in Iceland has likely evolved for several million years outside the reach of processes that mix this bacterial complex across earth’s temperate zones 
    Morris, Cindy E.; Carrera, Natalia Ramirez; Berge, Odile; Lacroix, Christelle; Monteil, Cécile; Chandeysson, Charlotte; Guilbaud, Caroline; Blischke, Anett; Sigurbjörnsdóttir, Margrét Auður; Vilhelmsson, Oddur Þór (2022-03)
    Here we report, for the first time, the occurrence of the bacteria from the species complex Pseudomonas syringae in Iceland. We isolated this bacterium from 35 of the 38 samples of angiosperms, moss, ferns and leaf litter collected across the island ...

    Quantum fluids of light in all-optical scatterer lattices 
    Alyatkin, Sergey; Sigurdsson, Helgi; Askitopoulos, Alexis; Töpfer, Julian; Lagoudakis, Pavlos (2021-09-22)
    One of the recently established paradigms in condensed matter physics is examining a system's behaviour in artificial potentials, giving insight into phenomena of quantum fluids in hard-to-reach settings. A prominent example is the matter-wave scatterer ...

    Stimuli-Responsive Properties of Supramolecular Gels Based on Pyridyl-N-oxide Amides 
    Jayabhavan, Sreejith Sudhakaran; Kristinsson, Baldur; Ghosh, Dipankar; Breton, Charlène; Damodaran, Krishna K. (2023-01-20)
    The nature of functional groups and their relative position and orientation play an important role in tuning the gelation properties of stimuli-responsive supramolecular gels. In this work, we synthesized and characterized mono-/bis-pyridyl-N-oxide ...

    Upper Miocene and Pliocene geomagnetic secular variation in the Borgarfjördur area of Western Iceland 
    Watkins, N. D.; McDougall, Ian; Kristjánsson, Leó (1977-06-01)
    A total of 362 successive lava flows, which were extruded at a regular rate between t= 6.7 and 1.6 Myr in the Borgarfjördur area of Western Iceland, have been subjected to palaeomagnetic study. In contrast to the result of a study by Wilson & McElhinny ...
