Geochemistry
​
The geochemical investigation performed during 28 October- 23 November 2017 mainly focused on the fumaroles and Ice Caves of both Mt. Melbourne and Rittmann. The following activities were performed:
​
- Thermal analysis of the fumarole areas.
​
​- Extended the exploration and mapping of MC3 Ice Cave on Mt. Melbourne and R5 on Mt. Rittmann.
​
- Installation of a temporary geochemical-meteo station in the Aurora Ice Cave, to test the possibility of continuously monitoring the gas and heat fluxes released by the cave.
​
- Installation of 2 microloggers to evaluate the heat flux from soil in Aurora Ice Cave.
​
- Download of almost 1 year long air temperature dataset from the micrologger inside Aurora Cave, and logging restart.
​
- 3D experimental survey of a portion of tunnel in Aurora.
​
​- Collection of 2 samples of gas in MC3 Ice Cave
​
- FTIR and UV measurements of gas in both volcanoes
​
- Investigation of Mt. Rittman's plumes using a visible and NIR sun-photometer.
