Siguršur Reynir Gķslason


I am a research professor at the University of Iceland's Institute of Earth Sciences, where I and my PhD students study water/rock, water/gas and water/biomass interactions by field and laboratory experiments.  Currently I serve on the board of directors of the European Association of Geochemistry and will become the vice president 1 January 2017.  I am the chairman of the Scientific Steering Committee of CarbFix, an international initiative to store carbon in basaltic rocks ( I was named International Association of Geochemistry (IAGC) Fellow for 2016,  - bestowed to a scientist who has made significant contributions to the field of geochemistry.

Professional Accomplishments

My main scientific contributions are 1) measuring the chemical and physical erosion rates of basaltic terrains and their role in the global carbon cycle, 2) quantifying the carbon storage potential of basaltic rocks, 3) measurement of the dissolution rates and dissolution mechanisms of volcanic glasses and minerals as a function of glass composition, aqueous solution composition and temperature and 4) assessing the environmental pressure from volcanic eruptions.

I have published over 100 scientific articles in peer-reviewed international scientific journals.  These articles had been cited 6163 times according to Google Scholar 14 October 2016.
