Announcement of three forthcoming meetings on Volcano-Ice Interactions
in 2007:
1. XXIVth IUGG General Assembly, 2 to 13 July 2007, Perugia, Italy;
Session JVS003: Ice -Volcano Interactions
A session on ice-volcano interactions is being organised at the 24th
IUGG General Assembly, which will take place between 2 and 13 July 2007
at Perugia in Italy http://www.iugg2007perugia.it/. Abstract submission
is now open, but the deadline for electronic submission of abstracts is
not until 31 January 2007. Details as follows:
There are many important interactions between volcanism and glaciation,
operating at different levels and over a wide range of timescales. In
several regions of the world volcanoes generate the elevation necessary
for glaciers and snow covers to form, while the deposition of
pyroclastic material and eruptive and geothermal activity impact
directly on glacier mass balance. On the other hand, expansion and
contraction of glaciers over millennia and the release of meltwater
during deglaciation can influence eruptive activity through the
overburden pressure release and infiltration of water into the volcanic
system. Catastrophic floods may be generated by subglacial eruptions and
geothermal activity in the form of lahars and jökulhlaups, while
landform evidence from moraines and flood and tephra deposits can
provide important information on past glacier extent and the
interactions between glacier fluctuations and eruptive activity. This
session welcomes contributions on any aspect of ice-volcano interactions
on Earth or on other bodies in the solar system, including results from
field, remote sensing and modelling studies. The aim is to provide a
forum for exchange of knowledge and ideas, particularly between
scientists form different disciplines, and to encourage future
collaborative research into these complex and challenging systems.
Sponsoring Association: IAVCEI in collaboration with: IAHS, UCCS, IGS
Convener: Ben Brock, University of Dundee, UK (b.w.brock@xxxxxxxxxxxx)
Co-Conveners: Andrés Rivera (arivera@xxxxxxx); Magnus Gudmundsson
(mtg@xxxxxxxxxxxxx)
2. 2nd Volcano-Ice Interaction on Earth and Mars Conference ("VII2"), to
be held at the University of British Columbia in Vancouver, Canada, June
19th-22nd 2007.
Meeting: This is a follow-up to the first Volcano-Ice Interaction on
Earth and Mars Conference, held in Reykjavik, Iceland in 2000, and will
also build upon the International Symposium on Earth and Planetary
Volcano-Ice Interactions, organized by the International Glaciological
Society (IGS), also in Reykjavik in June 2006. The VII2 conference is
sponsored by the IAVCEI Working Group on Volcano-Ice Interaction,
University of British Columbia (UBC), Geological Survey of Canada (GSC),
and the University of Pittsburgh, USA. Further support from the IAVCEI
Commissions on Explosive Volcanism (CEV) and Volcanogenic Sediments
(CVS) and the United States Geological Survey (USGS) is pending. VII2
will in particular be a chance to see and discuss the many superb
examples of non-basaltic volcano-ice interaction that are preserved in
British Columbia and north-west USA.
Field Trips: Three field trips are planned. These include a
pre-conference trip to the Cascades, a local mid-conference trip to
Whistler, BC, Canada and a post-conference trip to northern BC.
Accommodation: UBC Campus and nearby parts of Vancouver
Conveners: Ben Edwards, Dickinson College, USA; Ian Skilling,
University of Pittsburgh, USA; Lionel Wilson, University of Lancaster,
UK. Hugh Tuffen, University of Lancaster, UK.
Further Information: To sign up for the mailing list, please contact Ian
Skilling (skilling@xxxxxxxx). The first circular will be emailed in
October 2006 to all those on the mailing list, and will include details
of registration and accommodation costs, details of field trips, program
schedule and deadline information. A Web Page for the conference will
be available from the end of November 2006. Abstract submission will be
online via the webpage and the deadline is 28th February 2007
3. Proposed session at AGU Joint Assembly, Acapulco, Mexico, May 22-25,
2007.
The following topic has been proposed as a special session for the 2007
Joint Assembly. Confirmation of the session, the abstract deadline and
other details will be posted at http://www.agu.org/meetings/ja07/.
Understanding Volcano-Ice Interactions: Integration of Field, Remote
Sensing, and Modeling Approaches.
Interactions between volcanism and snow or ice lead to a diversity of
eruption products, landforms and hazardous phenomena. Examples include
the formation of steep-sided tuyas during eruptions under ice caps and
the generation of lahars by mixing of pyroclastic materials with summit
snowpack. While often poorly observed, the consequences can be highly
hazardous to adjacent communities. Furthermore, subglacial edifices
exposed by glacier removal yield information on past climatic
conditions. The potential for volcano-ice interactions to have occurred
on Mars means that a rigorous understanding of the terrestrial
glaciovolcanism is necessary before we can understand the implications
for the evolution of the martian climate and environment. Progress
towards understanding the variety and consequences of volcano-ice
interactions comes though field studies of exposed edifices and
deposits, remote sensing and geophysical monitoring, and modeling of the
physics of heat transfer and fluid dynamics. In this session we seek to
bring together practitioners in these sub-disciplines to highlight
recent advances in our understanding and to map the path to further
progress in elucidating the mechanisms and consequences of volcano-ice
interactions.
