    The chemical composition of rivers and snow affected by the 2014/2015 Bárðarbunga eruption, Iceland 
    Galeczka, Iwona; Sigurdsson, Gunnar; Eiriksdottir, Eydis Salome; Oelkers, Eric H.; Gíslason, Sigurður Reynir (Elsevier BV, 2016-04)
    The 2014/15 Bárðarbunga volcanic eruption was the largest in Iceland for more than 200 years. This eruption released into the atmosphere on average 60,000 tonnes/day of SO2, 30,000 tonnes/day of CO2, and 500 tonnes/day of HCl affecting the chemical ...

    Direct evidence of CO2 drawdown through enhanced weathering in soils 
    Linke, Tobias; Oelkers, Eric; Möckel, Susanne Claudia; Gíslason, Sigurður Reynir (European Association of Geochemistry, 2024-04-30)
    The ability of engineered enhanced weathering to impact atmospheric CO2 has been challenging to demonstrate due to the many processes occurring in soils and the short time span of current projects. Here we report the carbon balance in an Icelandic ...

    Hydrothermal and Cold Spring Water and Primary Productivity Effects on Magnesium Isotopes: Lake Myvatn, Iceland 
    Pogge von Strandmann, Philip A. E.; Burton, Kevin W.; Opfergelt, Sophie; Eiríksdóttir, Eydís Salóme; Murphy, Melissa J.; Einarsson, Árni; Gíslason, Sigurður R. (Frontiers Media SA, 2020-04-30)
    Lake Myvatn, Iceland, is one of the most biologically productive lakes in the northern hemisphere, despite seasonal ice cover. Hydrothermal and groundwater springs make up the dominant source to this lake, and we investigate their Mg isotope ratio to ...

    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 ...

    Using Mg Isotopes to Estimate Natural Calcite Compositions and Precipitation Rates During the 2010 Eyjafjallajökull Eruption 
    Pogge von Strandmann, Philip A. E.; Olsson, Jonas; Luu, Tu-Han; Gíslason, Sigurður Reynir; Burton, Kevin W. (Frontiers Media SA, 2019-02-01)
    Chemical weathering of silicate rocks is a key control on the long-term climate, via drawdown of atmospheric CO 2 . Magnesium isotopes are increasingly being used to trace weathering, but are often complicated by several coincident fractionating ...
