    Evaluating the carbon sequestration potential of volcanic soils in southern Iceland after birch afforestation 
    Hunziker, Matthias; Arnalds, Olafur; Kuhn, Nikolaus (Copernicus GmbH, 2019-08-06)
    Afforestation is a strategy to sequester atmospheric carbon in the terrestrial system and to enhance ecosystem services. Iceland's large areas of formerly vegetated and now degraded ecosystems therefore have a high potential to act as carbon sinks. ...

    Icelandic Inland Wetlands: Characteristics and Extent of Draining 
    Gudmundsson, Jon; Brink, Sigmundur H.; Arnalds, Olafur; Gisladottir, Fanney O.; Oskarsson, Hlynur (Society of Wetland Scientists, 2016-06-09)
    Iceland has inland wetland areas with soils exhibiting both Andosol and Histosol properties which are uncommon elsewhere on Earth. They are generally fertile, with higher bird-nest densities than in similar wetlands in the neighboring countries, with ...

    The Icelandic volcanic aeolian environment: Processes and impacts — A review 
    Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Olafsson, Haraldur (International Society for Aeolian Research, 2016-02-15)
    Iceland has the largest area of volcaniclastic sandy desert on Earth or 22,000 km2. The sand has been mostly produced by glacio-fluvial processes, leaving behind fine-grained unstable sediments which are later re-distributed by repeated aeolian events. ...

    Impact of dust deposition on the albedo of Vatnajökull ice cap, Iceland 
    Wittmann, Monika; Groot Zwaaftink, Christine; Steffensen Schmidt, Louise; Guðmundsson, Sverrir; Pálsson, Finnur; Arnalds, Olafur; Björnsson, Helgi; Thorsteinsson, Throstur; Stohl, Andreas (Copernicus GmbH, 2017-03-23)
    Deposition of small amounts of airborne dust on glaciers causes positive radiative forcing and enhanced melting due to the reduction of surface albedo. To study the effects of dust deposition on the mass balance of Brúarjökull, an outlet glacier of the ...

    Interactions between the atmosphere, cryosphere, and ecosystems at northern high latitudes 
    Boy, Michael; Thomson, Erik; Acosta Navarro, Juan C.; Arnalds, Olafur; Batchvarova, Ekaterina; Bäck, Jaana; Berninger, Frank; Bilde, Merete; Brasseur, Zoé; Dagsson-Waldhauserova, Pavla; Castarède, Dimitri; Dalirian, Maryam; de Leeuw, Gerrit; Dragosics, Monika; Duplissy, Ella-Maria; Duplissy, Jonathan; Ekman, Annica; Fang, Keyan; Gallet, Jean-Charles; Glasius, Marianne; Gryning, Sven-Erik; Grythe, Henrik; Hansson, Hans-Christen; Hansson, Margareta; Isaksson, Elisabeth; Iversen, Trond; Jonsdottir, Ingibjorg; Kasurinen, Ville; Kirkevåg, Alf; Korhola, Atte A.; Krejci, Radovan; Kristjánsson, Jón Egill; Lappalainen, Hanna K.; Lauri, Anniina; Leppäranta, Matti; Lihavainen, Heikki; Makkonen, Risto; Massling, Andreas; Meinander, Outi; Nilsson, Douglas; Olafsson, Haraldur; Pettersson, Jan B.C.; Prisle, Nønne; Riipinen, Ilona; Roldin, Pontus; Ruppel, Meri; Salter, Matthew; Sand, Maria; Seland, Øyvind; Seppä, Heikki; Skov, Henrik; Soares, Joana; Stohl, Andreas; Ström, Johan; Svensson, Jonas; Swietlicki, Erik; Tabakova, Ksenia; Thorsteinsson, Throstur; Virkkula, Aki; Weyhenmeyer, Gesa; Wu, Yusheng; Zieger, Paul; Kulmala, Markku (Copernicus GmbH, 2019-02-14)
    The Nordic Centre of Excellence CRAICC (Cryosphere–Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011–2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research ...

    Mineralogical and Chemical Records of Icelandic Dust Sources Upon Ny-Ålesund (Svalbard Islands) 
    Moroni, Beatrice; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Crocchianti, Stefano; Vivani, Riccardo; Cappelletti, David (Frontiers Media SA, 2018-11-05)
    This work aims to identify the geochemical and mineralogical markers of Icelandic dust and to differentiate it from the dust of local origin deposited at the Ny-Ålesund station. We characterized representative sediment samples from Iceland and Svalbard ...

    The Spatial Variation of Dust Particulate Matter Concentrations during Two Icelandic Dust Storms in 2015 
    Olafsson, Haraldur; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Magnúsdóttir, Agnes Ösp (MDPI AG, 2016-06-03)
    Particulate matter mass concentrations and size fractions of PM1, PM2.5, PM4, PM10, and PM15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. Images from a camera network were used to estimate the ...

    Temporal and spatial variability of Icelandic dust emissions and atmospheric transport 
    Groot Zwaaftink, Christine; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Eckhardt, Sabine; Prospero, Joseph M.; Stohl, Andreas (Copernicus GmbH, 2017-09-14)
    Icelandic dust sources are known to be highly active, yet there exist few model simulations of Icelandic dust that could be used to assess its impacts on the environment. We here present estimates of dust emission and transport in Iceland over 27 years ...
