EGU 2013 Session - Volcanic ash dispersal, deposition and tephra deposits
From: Karen.Fontijn@xxxxxxxxxxxxxx
****************************************************************************************
Dear all,
We would like to draw your attention to session GMPV33/AS3.18/NH2.8 focussed on tephra studies, to be held at the EGU 2013 General Assembly in Vienna, Austria, 7 - 12 April 2013. More session details can be found below. We encourage contributions from the whole range of tephra studies, from ash formation to dispersal and deposition, from field observations to experimental studies and modelling.
The abstract deadline is 9 January 2013. There are however funding possibilities, including for young European researchers, or for non-European scientists, if abstracts are submitted by 30 November 2012. More information on financial support possibilities can be found on: http://www.egu2013.eu/support_and_distinction/financial_support.html

GMPV33/AS3.18/NH2.4
Volcanic ash dispersal, deposition and tephra deposits: constraints from field, ground-based and satellite observations and models
Recent years have seen significant advances in our capacity to track volcanic ash clouds remotely (from space, or from the ground), and in the modelling of volcanic ash plumes. These technical advances have significant potential to assist the reconstruction of past eruptions, to improve real-time operational forecasting during volcanic eruptions, and to develop further the modelling of hazards associated with tephra dispersal and fallout. But many challenges remain: do we know enough about the optical properties of 'ash' for satellite detection and measurement of volcanic ash plumes? Are the physical properties of ash (e.g., density) characterised in sufficient detail for tephra dispersal modelling, and how can models help us to reconstruct the key parameters that characterise ancient tephra fall deposits? What are typical uncertainties related with the different approaches and techniques? And what are the 'gaps' between the approaches: the coarse tephra that cannot be 'seen' by satellite, or the fine ash that is absent from the geological record? This session invites contributions across the full spectrum of this topic, with the aim of stimulating further discussion and future work.
Convener: David Pyle
Co-Conveners: Simona Scollo , Karen Fontijn , Antonio Costa
We hope to see you in Vienna and look forward to exciting presentations and discussions!
