Erebus hydrogen emissions, oxidation state, phase equilibria, and anorthoclase megacrystalsThe continuous measurement of molecular hydrogen (H2) emissions from passively degassing volcanoes has recently been made possible using a new generation of low-cost electrochemical sensors. We have used such sensors to measure H2, along with SO2, H2O and CO2, in the gas and aerosol plume emitted from the phonolite lava lake at Erebus volcano, Antarctica. The measurements were made at the crater r

STUDY AND MONITORING OF ACTIVE VOLCANOES: DECEPTION ISLAND - PICTO-36051-2005ENGLISH The purpose of this project is to make a full study of the Deception Island volcanic system. The geologic research will be carried on through various disciplines. Thus, structure, volcanic stratigraphy, and petrology of magmatic and piroclastic sequences, together with volume and gas composition, will be analyzed with special emphasis in the island seismologic monitoring. In recent years t

Provenance data from Quaternary tills in the Transantarctic MountainsTwo high-elevation moraines sequences in the southern-central Transantarctic Mountains were sampled to characterize provenance changes through time. Samples were collected in transects across the moraine system at the base of Mt. Achernar, at the head of the Law Glacier and at Mt. Howe, at the head of Scott Glacier. Till samples were analyzed for particle size, pebble petrography, quantitative x-r
