dc.description.abstract	Chemical denudation rates during the 2014–15 Bárðarbunga eruption, calculated using river chemical fluxes, increased substantially confirming that volcanic activity and its products such as fresh lava, and acidic volatiles accelerates these rates. Although the long-term net effect of the combined input of volcanic gases and basalt from the eruption appears to be the overall net drawdown of CO2, it is found that the rapid release of acid gases to surface waters once the basaltic lava comes in contact with surface waters will lead to a short-term release of CO2 from these waters.
dc.description.sponsorship	This study was funded by Ríkislögreglustjórinn Almannavarnadeild – The National Commissioner of the Icelandic Police, Jarðvísindastofnun Háskólans – Institute of Earth Sciences University of Iceland, Veðurstofa Íslands – IMO, and Rannsóknamiðstöð Íslands – The Icelandic Centre for Research RANNÍS (Grant # 163531-051 and 163531-052). The authors would like to thank to all of those who helped to collect the water samples. We also thank all the colleagues and co-workers from Institute of Earth Sciences and IMO for fruitful discussions during the time of the Bárðarbunga unrest.
