SUMMARY:Bubbles and bangs: sensing volcanic emissions - Dr Clive Oppenheim

DESCRIPTION:The gases contained in magma are the protagonists of volcanic 
 eruptions. Emissions of sulfur\, chlorine and fluorine from volcanoes can 
 also have profound impacts on the atmosphere\, climate and environment. Me
 asurements of volcanic effluents are therefore vital in understanding how 
 volcanoes work\, assessing volcanic hazards\, and evaluating the links bet
 ween volcanism and the Earth system. But they are not easy to make using m
 ore conventional sampling techniques\, not least because of the inherent d
 anger of working around an active volcano. This presentation summarises so
 me relevant developments in ultraviolet and infrared remote sensing\, and 
 illustrates their application in probing the plumbing systems of several a
 ctive volcanoes\, including Erta ‘Ale in Ethiopia\, and Mt. Erebus in An
 tarctica
