********************************************************************* J.D.L. White <james.white@xxxxxxxxxxx> ********************************************************************* Dear All, Many thanks to all of you who have already submitted abstracts to the IAVCEI 2008 session 3-c "Subaqueous explosive volcanism". If you are yet to submit an abstract to this session please note that the submission deadline is 1st April. This session addresses the nature of explosive volcanism in marine, lacustrine and englacial settings. The deposits of such eruptions are of greater volume and economic significance than those of more intensely studied subaerial eruptions, and eruptions can involve any magma composition. Styles of eruption are incompletely understood, and many studies focus on identification of similarities with better-known subaerial eruption styles. This session aims to bring together research on modern subaqueous eruptions, emergent eruptions that represent the shallowest but only visible part of subaqueously initiated eruptions, and deposits of ancient subaqueous eruptions. Eruptions initiated beneath glaciers form their own bodies of water into which eruption continues, and their deposits exposed as a result of glacial retreat offer accessible study targets for many aspects of explosive subaqueous eruptions. This session will focus on: - Fragmentation processes in explosive submarine, subglacial and emergent eruptions - Geophysical and other observations of subaqueous to emergent eruptions - Dispersal characteristics of subaqueous eruptions - Processes of particle transport and deposition from subaqueous eruptions - Interpretation of heat-retention features in deposits of subaqueous eruptions - Role of steam in subaqueous plumes, currents, and deposits - Relationships of deposit mineralization to processes of subaqueous eruptions - Review papers integrating interpretation of deposit features with observed processes during eruptions are particularly welcomed Commissions: CEV, VII, CEV Conveners: J.D.L.
