IAVCEI 2004, Pucón - Chile, November 14-19
(1) Special Session (November 14-19)
Volcanic Lakes and environmental impact of volcanic fluids on ambient waters
We invite contributions on a wide range of topics that deal with the use of hydrothermal fluids in eruption monitoring, estimates of fluxes of volcanic elements in lakes, as well as environmental impacts of volcanic emissions on surface waters. Many hot springs are enriched in toxic elements like As, Hg, Tl, Li, B, F, as well as heavy metals. These elements are transported downstream where waters may be used for household or irrigation uses. Many hot spring fluids are used for thermal bathing as well and accidental water ingestion of such fluids is potentially harmful. Contributions on environmental problems as well as secular variations in hot spring chemistry are welcome.
Conveners: Johan C. Varekamp (jvarekamp@wesleyan.edu), Minoru Kusakabe (kusakabe@misasa.okayama-u.ac.jp), Fernando Pedrozo (madyfer@bariloche.com.arg), Manfred J. van Bergen (vbergen@geo.uu.nl)

After the IAVCEI meeting, a workshop on Volcanic Lakes is held in the small ski resort of Caviahue, nestled on the slopes of Copahue volcano, about 400 km north of Bariloche, Argentina. Topics of the workshop are the many aspects of volcanic lakes at the interface of volcanic and surface processes. Two days of lectures, talks and video presentations are planned on the volcanology, geochemistry and bacterial activity in volcanic lakes and the rivers and/or springs that feed them. Fieldtrips are organized to the Rio Agrio (pH~1, 40 oC), the giant glacial Lake Caviahue (pH=2.5) and a variety of thermal areas with the largest thermal health spa in the southern hemisphere in Copahue village. The headwaters of the Rio Agrio, which are ~70 % of magmatic origin, precipitate bright red beds of hematite on the river bed surface, and the waters are saturated in jarosite and gypsum. This site may be a modern terrestrial analog of the Opportunity Landing site on Mars, and these acid waters are teeming with bacterial life. NSF has recommended this meeting for funding and, pending final approval, we can provide partial financial support to USA students and other participants with demonstrated financial needs. Vans will drive participants from the IAVCEI meeting to the workshop and back. Limnologists, geochemists, volcanologists and planetary geologists are invited to participate and present their work on this range of topics.
