Multiparametric Monitoring System of Mt. Melbourne Volcano (Victoria Land, Antarctica)

Area of Science:

• Geosciences and Volcanology
• Polar Research and Environmental Monitoring
• Geophysical Instrumentation and Engineering

Background:

• Volcanic eruptions, even from remote locations like Antarctica, pose significant global hazards, as evidenced by past events.
• Effective volcano monitoring is essential for risk mitigation but is severely challenged by extreme polar conditions.
• Antarctic volcanoes require dedicated monitoring systems to understand and predict potential hazards.

Purpose of the Study:

• To describe a novel multiparametric monitoring system deployed on Melbourne volcano, Antarctica.
• To detail the strategies employed to ensure system efficiency and reliability in extreme polar environments.
• To provide a model for establishing similar volcano monitoring infrastructures in other polar regions.

Main Methods:

• Deployment of a multiparametric network including seismic, geochemical, and thermal sensors.
• Installation of robust powering, transmission, and data acquisition systems designed for polar conditions.
• Strategic placement of monitoring stations within fumarolic ice caves for protection and stable temperatures.

Main Results:

• A functional multiparametric monitoring system was successfully established on Melbourne volcano.
• Specific technological solutions were implemented to ensure operational efficiency despite extreme cold and wind.
• Fumarolic ice caves provided a protected environment, maintaining temperatures near 0°C and safeguarding instruments.

Conclusions:

• The developed monitoring system demonstrates the feasibility of effective volcano surveillance in Antarctica.
• The strategies for instrument protection, energy management, and site selection are transferable to other polar volcanic regions.
• This work contributes to enhancing global volcanic hazard assessment capabilities by enabling monitoring of previously under-observed volcanoes.
