We present an exploratory study examining the use of airborne remote-sensing observations to detect ecological responses to elevated CO2 emissions from active volcanic systems. To evaluate these ecosystem responses, existing spectroscopic, thermal, a

Self-potential, soil CO2flux, and temperature on Masaya volcano, Nicaragua

Autor: Charles B. Connor, J. L. Lewicki, K. St-Amand, W. Spinner, John Stix

Publikováno v: Geophysical Research Letters. 30

We investigate the spatial relationship between self-potential (SP), soil CO{sub 2} flux, and temperature and the mechanisms that produce SP anomalies on the flanks of Masaya volcano, Nicaragua. We measured SP, soil CO{sub 2} fluxes (

Accumulation chamber measurements of methane fluxes: application to volcanic-geothermal areas and landfills

Autor: J. L. Lewicki, Carlo Cardellini, Domenico Granieri, Giovanni Chiodini, Francesco Frondini, L. Peruzzi

Direct measurement of present day CH4 diffuse degassing from the soil represents an effective tool to better estimate the degassing rate of individual sources and to calibrate global Earth degassing estimates. While many data exist on CH4 emissions f
