Description :
By using major ion, microparticle, and stable-isotope data obtained from ice cores, it is possible to assess the degree of atmospheric loading and potential climatic importance of major volcanic eruptions that occured prior to 1880. The AA. have identified both silicate ash particle and sulfuric acid fallout from the 1783 Laki eruption in Iceland in the Geenland Ice Sheet Project 2 (GISP2) firn and ice core collected in 1989. The AA. use this information, coupled with available information on the Laki event, to reassess atmospheric conditions following this major 18th century eruption.
