DESCRIPTION:Sulfur emissions from volcanoes influence Earth’s climate\, 
 have profound effects on the local environment and human health during vol
 canic eruptions\, and provide a tool to monitor volcanic activity from spa
 ce. How much sulfur is released during volcanic eruptions is a complex int
 erplay of magma storage pressure\, temperature\, melt sulfur content\, and
  melt redox state. Sulfur isotope fractionation during sulfur degassing an
 d sulfide saturation provides information on the fate of sulfur in magmati
 c systems. Sulfur isotopes ratios measured in melt inclusions and glasses 
 in oxidised magmas from ocean islands and arc magmas can help to constrain
  sulfur speciation in the gas and melt during melt evolution\, and how cha
 nges in redox can influence where sulfur ends up in magmatic systems.
