Georgina Sawyer‘s research focuses on the development and application of ground-based remote sensing techniques that are used to investigate the composition, flux and atmospheric chemistry of gas emitted from volcanoes. In particular, she uses open-path Fourier transform infrared (OP-FTIR) spectroscopy to characterise the composition of plumes (detectable gases include H2O, CO2, CO, SO2, HCl, HF, OCS) and ultra-violet differential optical absorption spectroscopy (UV-DOAS) to measure the emission rate of SO2.Icelandic eruptions, degassing, and spectroscopy.
