EGU 2016. Session: VOLCANIC GAS EMISSIONS - GMPV6.2/AS4.26/NH2.9
*****************************************************************************************************
Dear Colleagues,
We would like to draw your attention to the session
Volcanic Gas Emissions - GMPV6.2/AS4.26/NH2.9 - at the EGU General Assembly 2016, held in Vienna
(Austria) from 17 - 22 April 2016. We
welcome your contributions on volcanic degassing. (EGU website: http://www.egu2016.eu/)
The abstract submission deadline is: 13 January 2016 13.00 CET.
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.
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.
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.
Don't hesitate to
contact us if you have any questions.
We look
forward to seeing you in Vienna.
All the best,
Giuseppe Salerno, Nicole Bobrowski, Christoph kern and Franco Tassi
