Data from Monitoring Volcanic Gases in Plumes and Ambient Air, Newberry Volcano, Oregon

September 21, 2021

This release presents volcanic gas monitoring data from periodic surveys and temporary instrument deployments at Newberry Volcano, Oregon. Measurements of plume-gas and ambient air compositions were obtained using single-gas industrial hydrogen sulfide (H2S) sensors and with multi-GAS (multiple Gas Analyzer System; Aiuppa et al., 2005; Shinohara, 2005; Lewicki et al., 2017) instruments that measure water vapor (H2O), carbon dioxide (CO2), sulfur dioxide (SO2), and H2S abundances. Discrete multi-GAS 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 discrete multi-GAS surveys were completed around Newberry caldera and a temporary continuous gas monitoring network was deployed. The temporary network was in place from August-October 2020 and included one multi-GAS station and four single-gas H2S monitors. Monitoring data from future surveys and instrument deployments will be added to this release as needed. References Aiuppa, A., Federico, C., Giudice, G., Gurrieri, S., 2005.
