Measurements of gases, particulates and energy from the plume, air, rocks, snow, ice, steam, gas and soils of Mt Erebus, Ross Island

The volcanic plume was sampled for acids, SO2, H2S, H2SO4, radioisotopes, particulates and metals. To quantify the plume output, SF6 analysis on air samples was completed.

Rock samples were taken and analysed for gases incorporated into volcanic bombs. Snow and ice samples from drill cores and crevasses and windscoop walls at Fang Glacier and Cape Bird and steam and gas samples from fumeroles were analysed for gas content. Soils were tested with CO2 surveys at Black Island, Western Crater and along Tramway Ridge and with a Geogas survey where vapour transport of trace species (including heavy metals) was quantified.
