The International Glaciological Society will hold an International
Symposium on Earth and Planetary Ice-Volcano Interactions in 2006. The
symposium will be held in Reykjavik, Iceland, with registration on 18
June and sessions on 19-23 June.
Ice-covered volcanoes pose many interesting challenges to scientists.
Numerous interesting phenomena arise from the thermal interaction
between hot volcanic materials and ice, here on Earth and elsewhere in
the Solar System; examples include the triggering of jokulhlaups, the
effect of internal layers of volcanic origin on radar signals, and the
relationship between older subglacially erupted volcanoes and the
glaciers in which they formed. Furthermore, ice-volcano interactions may
cause major hazards such as lahars, jokulhlaups, and explosive
eruptions. An improved understanding of these topics can only be
advanced through multidisciplinary research, drawing together such
diverse fields as remote sensing, fieldwork, and modeling. This
symposium provides a forum for researchers from a variety of backgrounds
to discuss the science of interactions of volcanoes and ice.
The suggested topics include:
(1) Effects of ice cover on volcanic systems:
a. Extraction of heat from magma to meltwater: subglacial and
supraglacial melting
b. The effect of glacier overburden and water pressure on volcanic
activity, seismic activity, and subglacial geothermal systems
c. Older subglacially formed volcanoes as evidence for past ice cover
thickness and extent
(2) Effects of geothermal and volcanic systems on glaciers and ice caps:
a. Mass balance (subglacial melting, the effect of tephra on albedo)
b. The effect of subglacial geothermal activity and eruptions on glacier
flow
c. Effects on the atmosphere and the ocean
d. Subglacial lake studies
(3) Geophysical exploration of ice-covered volcanoes:
a. Looking through the ice (radio echo soundings, etc.)
b. Detection of subglacial geothermal activity (surface depressions;
chemicals in meltwater)
(4) Information from internal acid layers and tephra layers:
a. On volcanic activity
b. On mass balance
(5) Volcano-glacier hazards:
a. Monitoring of ice-covered volcanoes and geothermal areas (inflation
of volcanoes, seismicity, meltwater chemistry, thermal activity, lake
levels)
b. Jokulhlaups, lahars
(6) Extraterrestrial ice-volcano interaction
