G-Cubed "OceanArc" Theme extended for another year
From: William Chadwick - NOAA Affiliate <william.w.chadwick@xxxxxxxx>G-Cubed "OceanArc" Theme extended for another year
****************************************************************************************************
An existing Theme in the journal Geochemistry, Geophysics, Geosystems (G-Cubed) titled: "Assessing Magmatic, Neovolcanic, Hydrothermal, and Biological Processes along Intra-Oceanic Arcs and Back-Arcs" has been extended for another year. We invite you to submit manuscripts to G-Cubed under this theme. Previous papers published under this theme are listed here: http://onlinelibrary.wiley.com/journal/10.1002/(ISSN)1525-2027/specialsection/OCEANARC1
This theme is aimed at understanding submarine magmatic and
hydrothermal processes along intra-oceanic arc and back-arc systems with
an emphasis on neo-volcanism. Submarine magmatic activity is a
fundamental process in the creation and consumption of the oceanic
crust, arguably the ocean’s largest geophysical and geochemical cycle.
Submarine magmatic activity is not only responsible for the creation and
recycling of the oceanic crust but also provides the energy to drive
hydrothermal activity that nurtures associated biological communities.
Despite extensive study of mid ocean ridge, arc, and back-arc submarine
volcanic provinces, active magmatism has only been observed recently
and only in the arc/back-arc environment. As a result, magmatic activity
remains poorly understood due to difficulty in detecting active sites,
their remote locations, and the generally non-continuous nature of their
activity.
This theme is driven by significant and recent progress on
relevant multidisciplinary topics including the origin and transport of
magma in subduction zones, the setting and style of eruptions, the
detection and remote identification of eruptive activity and eruptive
mode, the formation and evolution of resultant hydrothermal activity,
and the potential for active volcanic sites to host and sustain
chemosynthetic biological communities. The transport, flux, and chemical
modification of magmatic volatiles are key variables that both cross
and link various disciplines. Volatiles modify subducted oceanic crust,
enhance melting in the mantle, drive eruptions, affect eruption style,
enhance hydrothermal alteration of the crust, and provide chemical
energy for microbial processes, which in turn nurture unique animal
species and ecosystems.
We look forward to your submissions. Thank you.
