************************************************************** From: Pierre Delmelle <pd512@xxxxxxxxxx> ************************************************************** Dear All, We would like to draw your attention to the following session on: Environmental Effects of Volcanic Emissions that will be convened at the 2008 IAVCEI General Assembly in Iceland. The abstract submission deadline is 1 April 2008. ___________________________________________ Environmental Effects of Volcanic Emissions http://www.jardvis.hi.is/page/I08-SYM4#4-c ___________________________________________ Volcanic volatile emissions - both during and between eruptions - can have pronounced and widespread impacts on the atmospheric, terrestrial and aquatic environments, including distal and proximal effects on air quality, soil contamination, marine and terrestrial surface water composition, and destruction or enhancement of vegetation. These environmental effects are mediated through interactions with the volcanic volatiles present in the gas and aerosol phases and/or adsorbed onto the surface of silicate ash particles. In this session, we welcome interdisciplinary contributions from geochemical, environmental, atmospheric and ecological perspectives, which highlight the local to regional scale fate of volcanic emissions in the environment. This session will focus on: - the tropospheric chemistry and transport of volcanic gases, aerosols and ash particles; - the aqueous chemistry and transport of volcanic volatiles; - the effects of volcanogenic ´pollution´ on the built environment, plants and soils; - volatile-ash interactions in volcanic plumes - the release of nutrients and toxic elements through dissolution processes of volcanic glass and metal salts adsorbed onto ash; - fertilization effects and impacts on biological productivity of volcanic emissions in marine or terrestrial surface waters, - marine-atmospheric interchange due to volcanic ash deposition onto the surface of oceans Conveners: Pierre Delmelle - pd512@xxxxxxxxxx Svend Duggen - sduggen@xxxxxxxxxxxxx Paul Frogner Kockum - paul.frogner-kockum@xxxxxxxxxx Clive Oppenheimer - co200@xxxxxxxxx ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
