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.
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.
In name of the IAVCEI Commission on Volcanic Lakes and GNS Science, New Zealand, we are delighted to present you the SECOND CIRCULAR of our upcoming 10th WORKSHOP ON VOLCANIC LAKES, to be held from 17 to 25 MARCH 2019 in Taupo and Rotorua, New Zealand.
The Workshop will be build around 8 Scientific Symposia during the first three days, followed by field work at Ruapehu, Waimangu and Lake Rotomahana. A post-CVL10 field trip to White Island is optional.
Here is access to the Second Circular, together with the customer-guide-to-temporary-admission-of-goods to enter your scientific gear. In the Second Circular you can find a detailed program, the 8 scientific symposia, online registration procedure, costs and extra reading.
Brynn O’Donnell, graduate student studying freshwater biogeochemistry at Virginia Tech University, USA, interviewed Dmitri Rouwet on the Lake Nyos gas burst and 30-years aftermath.
Brynn runs ‘Submerge’ podcast to exploit her passion for science communication, dixit: “‘Submerge’ dedicates to exploring the various ways our perceptions and beliefs about water can shape our relationship with it.”
