Geological Society of America Cordilleran Section Meeting, Bellingham, WA, May 4-6, 2007
A session of relevance to volcano-ice interactions researchers will take place at the GSA Cordilleran Meeting. All conference details can be found at http://www.geosociety.org/sectdiv/cord/07cdmtg.htm
8. Active Volcano-Glacier Interactions: Process, Products, Hazards.
This session will address the interaction between glacial ice and active volcanoes. Unrest at ice-clad volcanoes (including intrusion, increases in fumarolic output, and eruptions) can profoundly disturb glacial cover, resulting in distinctive seismicity, avalanche, debris flow, flood generation, and dramatic changes in glacier topography and motion. Recent activity in Alaska and the Cascades have highlighted these processes and products and provided new and sometimes surprising glimpses into the behavior of ice during eruptions. This session will present recent examples of volcano-ice interaction and what has been learned about physical process and resulting hazards.
Special Session at AGU Joint Assembly, Acapulco, Mexico, May 22-25, 2007.
A session on volcano-ice interactions will take place at the 2007 Joint Assembly. The abstract deadline is 1 March 2007. All other conference details will be posted at http://www.agu.org/meetings/ja07/. V06: Understanding Volcano-Ice Interactions: Integration of Field, Remote Sensing, and Modeling Approaches.
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.
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.
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.

Workshop on Surtseyan volcanism: shallow, subaqueous explosive eruptions. 1-10 October, 2007, Utah and California, USA. JDL White and BD Pauly, conveners.
This workshop will focus on deposits of two well-preserved Quaternary surtseyan volcanoes, each of which erupted in one of the extensive pluvial lakes of the western USA. There are two primary targets. The first is Pahvant Butte, in Utah, which erupted beneath ~ 80m of water in Lake Bonneville and consists of a basal subaqueously emplaced tephra mound capped by a fairly typical tuff cone. The second will be Black Point volcano, erupted beneath ~200 m of water in the precursor to Mono Lake, California. Side trips are intended to Tabernacle volcano (Utah), Panum Crater (Mono Lake), and Ubehebe craters (Death Valley). Topics to be addressed are: subaqueous explosive eruption processes; primary subaqueous deposits from the eruptions; syn-eruptive redeposition; post-eruptive reworking and sedimentation; palagonitization and other alteration of young basaltic glass.
