We welcome submissions to the AGU session Multidisciplinary perspectives on volcanic lakes to be held during the 2021 Fall Meeting, from 13th to 17th of December. As the meeting will be both in-person and virtual, we strongly welcome contributions from early-career scientists and scientists from low-income countries. The AGU online abstract submission is now open, and will close on Wednesday 4st of August at 23:59 EDT.
Session Title: V014. Multidisciplinary perspectives on volcanic lakes
Section: Volcanology, Geochemistry and Petrology
Volcanic lakes are spectacular features of our planet. They also are windows into magmatic-hydrothermal systems, ideal natural laboratories to study interactions between the lithosphere, hydrosphere and atmosphere in volcanic environments, as well as interactions between the geosphere and biosphere inside their water body. A multidisciplinary measurement and modeling approach incorporating scientific fields such as volcanology, geochemistry, geophysics, limnology, microbiology, hydrogeology and economic geology has developed over the years to better understand volcanic lake systems. Such an approach also aims to forecast and mitigate hazards associated with volcanic lakes, such as phreatic and limnic eruptions, acid seepage, and lahars.
We therefore seek contributions related to studies of volcanic lakes from a broad range of perspectives, including:
- Geochemical, geophysical and microbiological characteristics and monitoring of volcanic lakes
- Hazard forecast and mitigation
- Environmental impacts of hyperacidic crater lakes
- Limnology and hydrogeology of volcanic lakes
- Modeling studies of volcanic lake processes
We look forward to seeing you, either in-person in New Orleans or online from anywhere.

Volcanic lakes are “windows” into magmatic-hydrothermal systems that become study objects for multi-disciplinary research approaches, and the lymph of our small but active Commission. After CVL9-Cameroon in March 2016, the IAVCEI Commission of Volcanic Lakes (CVL) reunited for CVL10 in Taupo, New Zealand, from 17 to 25 March 2019.
The meeting aimed at bringing together volcano scientists from a wide range of sub-disciplines, including physical volcanology, hydrology, limnology, biochemistry, geochemistry and geophysics, all with a view toward establishing broad communication amongst the disciplines and development of holistic models of volcanic lake environments. The goals of the workshop are to provide ample opportunity for exchange of ideas around data collection and monitoring methodologies in volcanic lake environments, hazard recognition and mitigation, and copious discussion of conceptual models for so-called “wet volcanic systems”.

Thirty-two participants from 12 countries attended the workshop, which was organised by Bruce Christenson, Agnes Mazot, Karen Britten and Brad Scott of Geological and Nuclear Science, New Zealand.
During the first three days (18-20 March 2019), seven different symposia were organised at the Great Lake Venue in Taupo, tackling the various topics of what volcanic lake research stands for: (1) Tracking lake water chemistry-The future of direct sampling of volcanic lakes (convened by María Martínez-Cruz Céline Mandon and Takeshi Ohba, 11 talks), (2) Gas emissions from acidic crater lakes (convened by Cindy Werner and Orlando Vaselli, 3 talks + 2 posters), (3) Hydrothermal systems surrounding volcanic lakes-surveys and models (convened by Joop Varekamp and Jennifer Lewicki, 6 talks), (4) Phreatic eruptions form Wet Volcanoes (convened by Bruce Christenson and Akihiko Terada, 5 talks), (5) The impact of volcanic lakes on society-from mythology to risk mitigation (convened by Hollei Gabrielsen and Dmitri Rouwet, 3 talks), (6) Limnology of Lake Nyos and its nephews-searching for strata (convened by Minoru Kusakabe and Bill Evans, 5 talks + 2 posters), and (7) Carbon dioxide degassing at volcanic lakes-theory and practice (convened by Artur Ionescu and Agnes Mazot, 4 talks). In the afternoon of day 2, the Phreatic Eruption symposium was followed by a round table session entitled “The role of crater lakes in forecasting phreatic eruptions”, panelled by Nico Fournier, Art Jolly, Bruce Christenson, Akihito Terada, Jennifer Lewicki, Takeshi Ohba, and Dmitri Rouwet. Notes were taken by Craig Miller. A major observation, also in the aftermath of the Ontake-2014 and Ruapehu-2007 phreatic eruptions, was: Is there such a thing as “blue sky eruption?” Or, are we not just detecting it? Answering this question remains a challenge for future research.

The scientific sessions were closed by the CVL Business Meeting (20 March 2019), that reported on the CVL activities of the past 9 years, from CVL7-Costa Rica-2010, over CVL8-Japan-2013, to CVL9-Cameroon-2016, until CVL10-New Zealand-2019. A positive balance of the commission’s activities was acknowledged by the commission members and participants. After nine years Dmitri Rouwet (INGV-Bologna, Italy) stepped back as the CVL Leader; Corentin Caudron (Université de Savoie, France, not present) and Jennifer Lewicki (USGS-Menlo Park, USA) were unanimously elected as the new CVL-co-Leaders. Bertram Boehrer (GFZ, Germany), Alain Bernard (ULB, Belgium) and Takeshi Ohba (Tokai University, Japan, ex-CVL Secretary, 2010-2013) decided to leave the CVL-Steering Committee. Céline Mandon (Yachay Tech University, Ecuador), Akihiko Terada (KSVO-TIT, Japan) and Maarten de Moor (OVSICORI, Costa Rica, not present) were added to the team of SC members, that is now composed of Bruce Christenson (CVL Secretary), Dmitri Rouwet (CVL webmaster), Greg Tanyileke (IRGM, Cameroon, ex-CVL Secretary 2013-2016), Agnes Mazot, Franco Tassi, Jacopo Cabassi (University of Florence, Italy), Raúl Mora-Amador (UCR, Costa Rica), Céline Mandon, Akihiko Terada, Maarten de Moor, and the two new co-Leaders Caudron and Lewicki.
This refreshed SC represents all continents, all ages and levels of experiences, besides all research fields of volcanic lake studies. Shortly after CVL10, the SC decided to organise the CVL11 Workshop in early 2022 at Lake Taal in the Philippines. CVL is delighted to bring the research group together at this enigmatic and potentially dangerous lake hosting volcano. The organisation of CVL11-2022-Philippines is in hands of Corentin Caudron, Alain Bernard and Phivolcs. The workshop will soon be promoted through IAVCEI newsletter, CVL mailing lists and on the CVL website https://iavcei-cvl.org/ and social media (https://www.facebook.com/Commission-on-Volcanic-Lakes-204310646248839/). See you all at the shore of Lake Taal in early 2022!

In the evening of March 20, the next Winner of the 2019-Kusakabe Award was announced during the Conference Dinner-Barbeque at the at Debrett’s Thermal Spa. The three nominated “heavy-weights” of our research during the past three decades, elected by the 2016-2019 CVL Steering Committee and an external evaluation commission, were: Bruce Christenson, Alain Bernard and Joop Varekamp (Wesleyan University, CT-USA). Joop Varekamp resulted the Winner of the 2019-Kusakabe Award. Congratulations Joop! Well deserved… thank you for your decades-long commitment, innovating and eclectic research and guidance.

After the scientific sessions and official Business Meeting CVL10 continued with field trips at the Tama Lakes (between Mt. Ruapehu and Mt. Ngauruhoe), Huka Falls, Wairakei Geothermal field, Wai-o-Tapu Geothermal Park, and joint sampling and measurement campaigns at Waimangu Volcanic Valley with a special focus on Lake Rotomahana (out of Rotorua). A climb to the Ruapehu Crater Lake with the entire group could, unfortunately, not take place due to adverse weather conditions. Needless to say that the magmatic-hydrothermal features in these field trips were breathtaking as well as very didactical. The group split on 25 March; some members decided to visit White Island/Whakaari independently.

The 2,000 € support by IAVCEI was awarded (5 x 400 €) to the young researchers/students, coming from overseas: Gino González (Costa Rica), Kaori Seki (Japan), Céline Mandon (Ecuador), Kyriaki Daskalopoulou (Greece), and Artur Ionescu (Romania).
See you in the Philippines in early 2022!
CVL would like to draw your attention to the upcoming MAAR8 Conference to be held ib Petropavlovsk-Kamtchatsky in late August 2020.
The Conference proposes a “Maar Lake session” where our work can be presented to a broader volcanological community.
Needless to say that MAAR8 includes exciting field trips, pre-, intra- and post-conference.
We hope to meet you in Kamchatka next summer.
