Mass-Independent Sulfur Isotopic Compositions in Stratospheric Volcanic Eruptions
International audience The observed mass-independent sulfur isotopic composition (33S) of volcanic sulfate from the Agung (March 1963) and Pinatubo (June 1991) eruptions recorded in the Antarctic snow provides a mechanism for documenting stratospheric events. The sign of 33S changes over time from a...
