1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Tjarda Roberts <tjarda.roberts@xxxxxxxxxxxxxx> Hello/Bonjour! We are organizing an in-person workshop on volcanic halogens: **Volcanic halogens across the earth system: from magma to atmosphere** ** 27-29 November 2024, in Orléans, France** We hope you will join us. Please SAVE THE DATE! Inscriptions will be in September, via an upcoming link on the website: https://www.lestudium-ias.com/events/volcanic-halogens-across-earth-system-magma-atmosphere <https://urldefense.com/v3/__https://www.lestudium-ias.com/events/volcanic-halogens-across-earth-system-magma-atmosphere__;!!IKRxdwAv5BmarQ!eSuTXONUSYdy_qLSPrXDr2F_0rdei4YVSKAYyZT90kj_wee00xE-8L8-9fT662Zw3UHHGsMKlsta9dg4WSkEb2o6fw$> We are seeking a wide participation across earth sciences, volcanology and atmospheric science communities, with a focus on volcanic halogens, and also more broadly about the behaviour and fate of related volcanic volatiles, through laboratory, field observation, and modeling studies of their magmatic and atmospheric processes. Hope to see you in Orléans! Tjarda Roberts, Nicole Bobrowski, Jonas Kuhn, Elena Maters, Alexander Nies, Thomas Wagner ----- ----- ----- Volcanic halogens across the earth system: from magma to atmosphere Wednesday 27th to Friday 29th November in Orléans (south of Paris), France. Venue: L' Ancien évêché (The Old Episcopal Palace) - Hôtel Dupanloup, Orléans, France Inscriptions will be in September, via an upcoming link on the website: https://www.lestudium-ias.com/events/volcanic-halogens-across-earth-system-magma-atmosphere <https://urldefense.com/v3/__https://www.lestudium-ias.com/events/volcanic-halogens-across-earth-system-magma-atmosphere__;!!IKRxdwAv5BmarQ!eSuTXONUSYdy_qLSPrXDr2F_0rdei4YVSKAYyZT90kj_wee00xE-8L8-9fT662Zw3UHHGsMKlsta9dg4WSkEb2o6fw$> Halogens play an important role in volcanic systems and their environmental impacts, alongside the main volcanic volatiles (water-vapor, carbon dioxide, and sulfur). Volcanic halogens (fluorine, chlorine, bromine, and iodine) influence the evolution of magmatic systems over time, the transport and fate of metals, and degassing processes leading to passive and eruptive emissions. On entering the atmosphere, halogens in volcanic emission-plumes can undergo chemical reactions that impact atmospheric chemistry, ozone and climate, and exert further influences on the environment and ecosystems by their deposition. Volcanic halogens interact with co-emitted ash particles and can influence the nitrogen, sulfur, and mercury cycles. Tracing volcanic halogens behavior and fate alongside other volatiles in the volcano-atmosphere-environment system is a complex challenge. Recent advances and newly developed research tools across laboratory experiments, field/observation and model studies are enabling to better quantify and characterize volcanic halogens processes within each of the various earth compartments and to bridge knowledge gaps from the mantle to the atmosphere. When brought together, these advances can collectively inform about the environmental impacts of volcanic halogens, their influence on large scale cycles and their evolution in the earth system (and for other planets), and the potential use of volcanic halogens datasets to contribute to observatory efforts to monitor and predict eruption hazards. 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ============================================================== 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).
