    A Bayesian hierarchical model for glacial dynamics based on the shallow ice approximation and its evaluation using analytical solutions 
    Gopalan, Giridhar Raja; Hrafnkelsson, Birgir; Adalgeirsdottir, Gudfinna; Jarosch, Alexander H.; Pálsson, Finnur (Copernicus GmbH, 2018-07-11)
    Bayesian hierarchical modeling can assist the study of glacial dynamics and ice flow properties. This approach will allow glaciologists to make fully probabilistic predictions for the thickness of a glacier at unobserved spatiotemporal coordinates, and ...

    Gradual caldera collapse at Bárdarbunga volcano, Iceland, regulated by lateral magma outflow 
    Gudmundsson, Magnus Tumi; Jónsdóttir, Kristín; Hooper, Andrew; Holohan, Eoghan P.; Halldorsson, Saemundur; Ofeigsson, Benedikt Gunnar; Cesca, Simone; Vogfjörð, Kristín S.; Sigmundsson, Freysteinn; Högnadóttir, Thórdís; Einarsson, Páll; Sigmarsson, Olgeir; Jarosch, Alexander H.; Jónasson, Kristján; Magnússon, Eyjólfur; Hreinsdóttir, Sigrún; Bagnardi, Marco; Parks, Michelle M.; Hjorleifsdottir, Vala; Pálsson, Finnur; Walter, Thomas R.; Schöpfer, Martin P.

C.; Spaans, Karsten; Jakobsson, Sigurður; Guðmundsson, Gunnar B.; Fridriksdóttir, Hildur María; Drouin, Vincent; Dürig, Tobias; Adalgeirsdottir, Gudfinna; Riishuus, Morten; Pedersen, Gro; van Boeckel, Tayo; Oddsson, Björn; Pfeffer, Melissa A.; Barsotti, Sara; Bergsson, Baldur; Donovan, Amy; Burton, Mike R.; Aiuppa, Alessandro (American Association for the Advancement of Science (AAAS), 2016-07-14)
    Large volcanic eruptions on Earth commonly occur with a collapse of the roof of a crustal magma reservoir, forming a caldera. Only a few such collapses occur per century, and the lack of detailed observations has obscured insight into the mechanical ...

    A Hierarchical Spatiotemporal Statistical Model Motivated by Glaciology 
    Gopalan, Giri; Hrafnkelsson, Birgir; Wikle, Christopher K.; Rue, Håvard; Adalgeirsdottir, Gudfinna; Jarosch, Alexander H.; Pálsson, Finnur (Springer Science and Business Media LLC, 2019-06-12)
    In this paper, we extend and analyze a Bayesian hierarchical spatiotemporal model for physical systems. A novelty is to model the discrepancy between the output of a computer simulator for a physical process and the actual process values with a ...

    Modelling debris transport within glaciers by advection in a full-Stokes ice flow model 
    Wirbel, Anna; Jarosch, Alexander H.; Nicholson, Lindsey (Copernicus GmbH, 2018-01-19)
    Glaciers with extensive surface debris cover respond differently to climate forcing than those without supraglacial debris. In order to include debris-covered glaciers in projections of glaciogenic runoff and sea level rise and to understand the ...

    Non-surface mass balance of glaciers in Iceland 
    Jóhannesson, Tómas; Pálmason, Bolli; Hjartarson, Árni; Jarosch, Alexander H.; Magnússon, Eyjólfur; Belart, Joaquín M. C.; Gudmundsson, Magnus Tumi (Cambridge University Press (CUP), 2020-06-02)
    Non-surface mass balance is non-negligible for glaciers in Iceland. Several Icelandic glaciers are in the neo-volcanic zone where a combination of geothermal activity, volcanic eruptions and geothermal heat flux much higher than the global average lead ...

    Winter mass balance of Drangajökull ice cap (NW Iceland) derived from satellite sub-meter stereo images 
    Belart, Joaquín M. C.; Berthier, Etienne; Magnússon, Eyjólfur; Anderson, Leif S.; Pálsson, Finnur; Þorsteinsson, Þorsteinn; Howat, Ian M.; Adalgeirsdottir, Gudfinna; Jóhannesson, Tómas; Jarosch, Alexander H. (Copernicus GmbH, 2017-06-30)
    Sub-meter resolution, stereoscopic satellite images allow for the generation of accurate and high-resolution digital elevation models (DEMs) over glaciers and ice caps. Here, repeated stereo images of Drangajökull ice cap (NW Iceland) from Pléiades and ...
