Summary

Results from discrete multi-GAS surveys are compiled herein. Gas composition data were obtained using portable multi-GAS instruments that record H2O, CO2, SO2, and H2S gas mixing ratios, GPS coordinates, and pressure and temperature data at 1Hz. Initial surveys were completed in 2017 at East Lake hot springs and Paulina hot springs. In response to reports of anomalous degassing in the summer of 2020 more extensive multi-GAS surveys were completed around Newberry caldera. In 2020 the instruments' CO2, SO2, and H2S sensor responses were verified in the field with portable gas standards; in 2017 the instrument was lab-calibrated only. The collection and processing of multi-GAS data have been discussed in Gunawan et al. (2017) and Lewicki [...]
