Dear colleagues,
We invite submissions to the following session on "Subglacial and Subaqueous and Volcanism: processes, products and impacts" (V16) at the 2011 IUGG General Assembly, Melbourne, 28 June-7 July.
Eruptions from subaqueous/subglacial vents are controlled by high confining pressure and interactions between magma and water/ice. Eruptions sourced in shallow water/thin ice can have sufficiently high eruption rates or eruption durations to breach the water/ice-air surface and become subaerial generating significant hazards and potential for highly explosive interaction between magma and water. The April 2010 eruption of Eyjafjallajokull not only affected the local population but became sufficiently violent to produce ash and steam-rich plumes rich in fluorine that caused,significant disruption to European airspace with a high cost local and global economies. For volatile-rich eruptions sourced in deep water and thick ice, high confining pressure reduces explosivity and the surrounding water affects eruption column dynamics. In contrast explosivity can be aided by magma/water interaction during effusive eruptions. The conditions extant during these eruptions form deposits that uniquely constrain evolving vent conditions over the course of eruptions, and can be important sources of paleo-climate information and water depth constraints. This session brings together researchers within the fields of submarine/sublaustine/
subglacial effusive and explosive volcanism where confining pressure and ambient conditions influence the eruption processes. Particular emphasis will be on eruption dynamics, transport mechanisms, and hazards.
Abstract deadlines: 17 January 2011 Close of abstracts for those applying for grants and funding
