Volcanic Gases

Volcanic gas researchers use measurements of volcanic gas composition and flux to provide insights into subvolcanic conditions and volatile cycling. Changes in volcanic gas composition and flux can indicate magma ascent or a change in conduit permeability, which are important eruption precursors. UAF researchers use direct fumarole sampling, in situ plume measurements and ground and satellite-based remote sensing to characterize background degassing, elucidate volcanic processes and identify changes in volcanic systems throughout the Aleutian Arc and around the world.
