Research Interests

I have several currently active research projects some of them funded by NSF. Below is a brief summary. I am currently looking for students, so if interested please contact me by email about projects in Iceland, Japan, Central America, East Africa and the Western USA! Volatile fluxes from volcanoes, remote sensing of volcanic gas emissions

The first historical eruption of Anatahan Volcano, Marianas: clues from volatile fluxes, ash leachates and deposits

Anatahan eruption and recent publications

Sampling of Aerosols in Poas Volcano Plume: using the TEM and SEM to study aerosol composition

Poas plume and recent publication

Masaya Volcano, Nicaragua: testing of mini DOAS a new instrument to measure SO2 in plumes

mini DOAS at Masaya Volcano

An eruption every 30 minutes: monitoring SO2 flux at Karymsky Volcano, Kamchatka

SO2 and ash blasts at Karymsky

First historical eruption of Anatahan, Marianas (May 2003)

Magmatic Volatiles: direct sampling

Oldoinyo Lengai, East African Rift: mantle volatiles and the eruption of carbonatite lavas

Sampling carbonatite lavas

Sources of CO2, N2, He and H2O in subduction zone volcanoes: Clues from Kudryavy Volcano, Kurile Islands, using COSPEC and >900°C gases

papers on Kudryavy and pictures

Along arc variations of magmatic volatiles: how do volatile compositions reflect subduction zone processes?

Constraining the volatile composition of the Icelandic mantle: NSF-funded work on N-isotopes from hot springs, phenocrysts and glasses. STUDENTS NEEDED!

Analyses of volcanic and hydrothermal gas and water samples

Fluids and Volatiles Laboratory at UNM

trace elements in fluids: Sector Field ICP-MS analyses of gas condensates

Isotopes: He, C, S, N, O, H. for clues about sources of volatiles

Instrumentation for continuous monitoring of fumarole gas composition

Field Areas
