7-7-7-7-7-7-7-7-7-7-7-7-7-7 From: Nicole <n.bobrowski@xxxxxxxxx> Dear Colleagues and Friends, Last year we had a great session on Volcanic and Tectonic degassing at EGU due to a lot of very interesting contributions. Next EGU in May 2020 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 this year is " *GMPV2.2/*AS4/NH2/TS13 *Volcanic and Tectonic degassing*" and it is convened by Nicole Bobrowski <https://meetingorganizer.copernicus.org/EGU2020/sessionprogramme#>, Carlo Cardellini <https://meetingorganizer.copernicus.org/EGU2020/sessionprogramme#>, Kyriaki Daskalopoulou <https://meetingorganizer.copernicus.org/EGU2020/sessionprogramme#>, Artur Ionescu <https://meetingorganizer.copernicus.org/EGU2020/sessionprogramme#> and Brendan McCormick. It is cross-advertised in another disciplines - atmospheric science, natural hazards and tectonic and structural geology - we had a interdisciplinary audience last year. We hope we will get another successful exchange in 2020. It would be great to see you in Vienna, and please submit your contribution until *13:00 CET of 15th of January 2020*. We are looking forward to your contributions! Session description: Areas found in different geodynamic settings, which are characterized by the presence of seismic, volcanic and geothermal activity contribute to the terrestrial degassing. Volatiles are of great importance because of their impact on a wide range of geological processes that take place from Earthâ??s mantle to the surface. Magma rises from depth and its decreasing pressure allows volatile species to partition to the gas phase. Bubbles form, grow, coalesce and gases start to flow through vesiculated magma. In addition, hydrothermal fluids that transport volatiles from the deep crust or mantle to the surface circulate in the crust enhancing geodynamic processes. Eventually, they escape towards the surface using tectonic structures and are released in the atmosphere, in some cases diffused through the soil, gas vents or dissolved in groundwater, in other cases forming large plumes or explosive eruption columns. Those fluids providing important information on processes in the interior of our planet. Fluids play an important role in volcanic eruptions and earthquake generation and thus, measuring gases constitutes a powerful tool for monitoring and understanding Earth. This session aims to merge different geo-disciplines and bring together researchers interested in the comprehension of the degassing processes that take place in various geodynamic regimes. Furthermore, identify the impact that the emissions can have on terrestrial environment, atmospheric composition, climate and human health at various temporal and spatial scales. We invite contributions discussing novel measurement techniques, field measurements, direct and remote ground- and space-based observations and modeling studies of degassing that can provide new insights into volcanic, tectonic and atmospheric processes on local and global scales. 7-7-7-7-7-7-7-7-7-7-7-7-7-7 ============================================================== Volcano Listserv is a collaborative venture among Arizona State University (ASU), Portland State University (PSU), the Global Volcanism Program (GVP) of the Smithsonian Institution's National Museum of Natural History, and the International Association for Volcanology and Chemistry of the Earth's Interior (IAVCEI).
