  • Quantification of iron-rich volcanogenic dust emissions and deposition over the ocean from Icelandic dust sources 

    Arnalds, Olafur; Ólafsson, Haraldur; Dagsson-Waldhauserova, Pavla (Copernicus PublicationsEuropean Geosciences Union, 2014-12-02)
    Iceland has extremely active dust sources that result in large-scale emissions and deposition on land and at sea. The dust has a volcanogenic origin of basaltic composition with about 10% Fe content. We used two independent ...
