****************************************************************************** NORDVULK Summer School on Volcano-Ice Interaction From: Magnus Gudmundsson <mtg@xxxxxxxxxxxxx> ****************************************************************************** Nordic Volcanological Center, Institute of Earth Sciences, University of Iceland IAVCEI-IACS Commission on Volcano-Ice Interactions Laugarvatn, Iceland, 30 June - 9 July 2009 The aim of the summer school is to give students in volcanology, glaciology and related fields a solid introduction to the field of volcano-ice interaction on Earth and other planets. Ice-covered volcanoes are found in many parts of the world and during glaciations a large number of the world's volcanoes had extensive ice cover. It has been suggested that a global ice cover existed about 600 Ma ago indicating that volcano-ice interaction may have been the dominant style of volcanism on land. Volcanism in the Polar Regions very often involves interaction with ice and negative impacts on the stability of ice sheets have been proposed. The interaction of magma and ice is therefore important in many areas and plays a significant role in the geological record and on the planet Mars. Awareness of the hazard caused by eruptions interacting with ice is also crucial as they often cause lahars and jökulhlaups, threatening inhabited areas. The summer school is aimed at responding to the needs of this expanding sub-discipline in volcanology and glaciology. It includes a combination of lectures from leading scientists, presentations from participants, field studies and observations. A strong field component will be an integral part of this summer school. Topics to be addressed: • Physics of volcano-ice interaction • Lithofacies of subglacial basalts and rhyolites • Landforms of volcano-ice interaction • Glacier response to volcanic eruptions • Physical volcanology of volcano-ice interaction • Applications of geochemical and isotopic techniques to subglacial eruption environments • Subglacial hydrology, jökulhlaups and lahars • Volcano-ice interaction hazards • Volcano-ice interaction on Mars and other planetary bodies • Volcano-ice interaction in the geological record as a paleoclimate proxy • Volcano-ice-climate interaction The venue at Laugarvatn in south Iceland is an ideal place for a summer school of this kind. It is located at the eastern margin of the complex of basaltic hyaloclastite mountains in the Western Volcanic Zone. Many type localities can be easily reached in afternoon trips from Laugarvatn. The last two days will be dedicated to a field excursion through the Eastern Volcanic Zone with its subglacially-formed rhyolitic rocks, basaltic hyaloclastite ridge landscape and the deposits of the spectacular jökulhlaups from the subglacial Katla volcano.
