Goldschmidt 2016. Subduction zone volcanism and its effects on climate, atmosphere, environment and vice versa
*****************************************************************************************************
Dear All,
the deadline for Gioldschmidt 2016 is approaching and I know that a lot of you are right now writing the abstracts … So if you search for a nice session, featuring the possibility to integrate climate, volcanogy, and chemistry, even on global scales, the following session 7g is your perfect choice ..
We hope to see you there.
Best wishes Tamsin Mather, Toshiya Mori, Anja Schmidt, Steffen Kutterolf
7g: Subduction zone volcanism and its effects on climate, atmosphere, environment and vice versa
Volcanism and volcanic emissions can have profound effects on Earth’s climate, atmosphere, and environment over short and long timescales. The average global surface cooling observed after the Pinatubo 1991 eruption, was a key illustration of the complicated interplay between large volcanic eruptions and the global climate. Longer term cumulative effects of passive degassing or pulses of volcanism have also been implicated in episodes of global change throughout Earth history. Furthermore, subtle feedbacks have been proposed whereby periods of climate change (e.g., glaciation) affect the rate of global volcanism and vice versa.
Most volcanic emissions of gas direct to the atmosphere are from subduction zone volcanoes. The last four decades of research, especially with its progress in analytics, satellite observations and climate modeling, have lead to key advances in our understanding of volcano-atmosphere and volcano-environment interactions as well as possible feedback mechanisms. Applying new multi-disciplinary approaches (e.g. combined tephrostratigraphic, petrological and climate modeling approaches) assist these, often global, perspectives of how volcanism interacts with climate, atmosphere, and environment and are powerful tools to unravel the dynamics and processes of these interactions, including a better understanding of how volatiles are recycled through arcs.
This session focuses on studies exploring longer time series, large-scale studies of subduction zone volcanism interacting with regional and global climate and the environment as well as their possible feedbacks, but relevant contributions from non-arc systems are also welcomed to form comparisons. This session links to session “Magmatic Volatiles: Sources, Fluxes and Sinks“ where individual systems are the focus.
