Last year we had a great session on Volcanic Gas Emission at EGU due to a lot of very interesting contributions. Next EGU in April 2018 we will have again the possibility to meet and discuss the science going on in our field in the same session. The name of the session is "GMPV4.5/AS3.8 Volcanic gas emissions" and it is convened by Nicole Bobrowski, Franco Tassi and Fatima Viveiros. It is cross-advertised in another disciplines - atmospheric science - we had a interdisciplinary audience last year. We hope we will get another successful exchange in 2017. It would be great to see you in Vienna, and please submit your contribution until 13:00 CET of 10th of January 2018.
We are looking forward to your contributions
Best wishes Franco, Fatima and Nicole
Session description:
As magma rises from depth, decreasing pressure allows volatile species to partition to the gas phase. Bubbles form, grow, coalesce and gases start to flow through vesiculated magma. Eventually, gases reach the surface and are released into the atmosphere, in some cases diffused through a soil or bubbling through a water pool, in other cases forming large plumes or explosive eruption columns.
Volcanic volatiles play a key role in magma transport and have significant impact on the style and timing of volcanic eruptions. Gas composition and flux may change with time, reflecting variations in the magmatic feeding system of volcanoes. Measuring volcanic gases therefore constitutes a powerful tool for monitoring and understanding active volcanoes.
This session will focus on all aspects of volcanic volatile degassing in the Earth’s system. We invite contributions discussing how novel measurement techniques, field measurements, direct and remote ground- and space-based observations and modeling studies of volcanic degassing can provide new insights into volcanic and atmospheric processes on local and global scales. Studies with the potential to improve our ability to forecast eruptions are specifically encouraged.

Measuring volcanic gases therefore constitutes a powerful tool for monitoring and understanding active volcanoes.
Volcanic emissions can also have profound impacts on terrestrial environment, atmospheric composition, climate and human health at various temporal and spatial scales. For instance, sulfur dioxide emissions can cause acid rain, influence aerosol formation and, if an eruption column reaches the stratosphere, cause global dimming and a decrease in Earth’s surface temperatures for years. Similarly, halogens can dramatically impact proximal ecosystems, influence the oxidation capacity of the troposphere and alter the stratospheric ozone layer.
