Volcanic and Natural Gas Emissions
New technologies for sensing, characterizing, and monitoring volcanic and natural gas emissions, including sulfur dioxide, nitrogen oxides, halides, helium, carbon dioxide, and methane.
Continuous volcano monitoring using a field-portable helium isotope detector
New technologies for sensing, characterizing, and monitoring volcanic and natural gas emissions are helping scientists better predict hazardous conditions and volcanic activity, potentially saving lives and property.
Characterizing magmatic gases directly in the field
USGS scientists, in collaboration with a private industry partner, have collaborated to adapt a commercially-available, industrial, in situ hydrogen chloride (HCl) and hydrogen fluoride (HF) analyzer for use in airborne and ground-based measurements of volcanic gases.
Using sUAS to measure methane fluxes
Combining NASA and USGS expertise to measure the amount, or flux, of methane being released from a bog using a sensor mounted on a sUAS to fill observation gaps from lack of flux towers in sensitive and remote locations.
