V12 – Geochemistry and Geophysics of Active Crater Lakes

Convener: Joop Varekamp (USA)

Co-Conveners: Corentin Caudron (Singapore), Dmitri Rouwet (Italy)

Active crater lakes provide the opportunity to watch inside magmatic-hydrothermal systems. The proto-type setting of “wet volcanoes” makes crater lakes prone to phreatic eruptions. Multidisciplinary approaches, by combining geophysical and geochemical measurements, and numerical and probabilistic modelling, have recently proven to be promising means to possibly reveal precursory signals of phreatic and phreatomagmatic eruptions. Hence, this section seeks contributions on how to measure and monitor crater lakes in relation with the activity of the underlying volcanoes.

P44. Volcanic lakes: multi-methodological and multi-disciplinary approaches for the characterization of the geosphere-biosphere interactions
Conveners: Dmitri Rouwet (INGV), Stefano Fazi (IRSA CNR), Jacopo Cabassi (UNIFI)
Corresponding e-mail: jacopo.cabassi@unifi.it

In this session, we welcome contributions focusing on peculiar approaches and methods of investigation of volcanic lakes from the geochemical, biological and limnological perspective. Studied lakes may be volcanic lakes from little maars to giant calderas, heated and acidic lakes, Nyos-type lakes (from the Lake Nyos gas disaster in Cameroon in 1986, when a limnic eruption occurred releasing huge amounts of CO2), bio-activity lakes (prone to the development of CO2(CH4)-rich gas reservoirs at depth mediated by bacterial activity), as well as lakes simulating the characteristics of a volcanic lake such as anthropic gas-rich lakes, sinkholes, etc. The aim is to encourage the expertise exchange among scientists in the study of microcosms such as limnic systems of volcanic environments, especially favouring the discussion and the development of new multidisciplinary and methodological research approaches, to shed light on the interactions occurring between geosphere and biosphere.
