This chapter reviews several facets of the study of volcanic gases. The focus of the review is
generally, but not exclusively on" high-temperature volcanic gases"—ie, gases emitted at …

Global carbon cycle models suggest that CO2 degassing from the solid Earth has been a
primary control of paleoatmospheric CO2 contents and through the greenhouse effect, of …

Degassing processes in basaltic magmas rich in both water and carbon dioxide can be
modeled using the solubilities of the endmember systems and the assumption of Henry's …

Samples from Kawah Ijen crater lake, spring and fumarole discharges were collected
between 1990 and 1996 for chemical and isotopic analysis. An extremely low pH (< 0.3) …

Airborne measurements of CO2 released from Oldoinyo Lengai, the only carbonatite-
erupting volcano in the world, reveal a CO2 flux of 0.055× 1012 mol/yr. This flux is …

General Physiology of Carbon Dioxide 2.4 Human Physiology of Carbon Dioxide: Normal …

Two diffuse soil CO2 flux surveys from the southern Lakki plain show that CO2 is mainly
released from the hydrothermal explosion craters. The correspondence between high CO2 …

Crater lakes, situated at the summits of active volcanos, act as condensers for heat and
volatiles released from near-surface magma bodies. Char acteristic traits of crater lakes …

The principal features, geotectonic settings and association with near-surface hydrothermal
mineral systems of ancient and present subaerial hot springs, fumaroles and geysers are …

We compiled time series of hydrothermal discharge consisting of 3593 chloride-or heat-flux
measurements from 24 sites in the Yellowstone region, the northern Oregon Cascades …
