Rapid detection and characterization of surface CO2 leakage through the real-time measurement of δ13 C signatures in CO2 flux from the ground
A portable stable carbon isotope ratio analyzer for carbon dioxide, based on wavelength scanned cavity ringdown spectroscopy, has been used to detect, locate, and characterize an intentional leakage of CO2 from an underground pipeline at the ZERT experimental facility in Bozeman, Montana. Rapid (1 h) walking surveys of the 100 m x 100 m site surrounding the pipeline were collected using this mobile, real-time instrument.
