USGS gas geochemist and colleagues at fissure 8

A USGS gas geochemist and colleagues from the United Kingdom carry multi-gas sensors as they approach the degassing fissure 8 cone during Kīlauea Volcano's 2018 eruption. The collaboration between HVO and UK universities allowed for better characterization of the aerosols emitted during the eruption, which, in turn, has better informed the larger volcanology community about the chemistry of these kinds of plumes.
