Russell studies Earth's past climate using geochemical proxies from cave deposits (speleothems). He is part of the Speleothem Science Research Group (www.speleothemscience.org) that spans the Schools of Geography and Earth Sciences. His current research focuses on the nature and causes of major climate transitions during the Quaternary Period, especially glacial terminations and abrupt 'millennial-scale' climate events, and how these play out regionally and hemispherically. He also studies recent palaeorainfall patterns over the past few thousand years (southern and eastern Australia, Indonesia, French Polynesia).
Russell runs a fully equipped microsampling and stable isotope laboratory dedicated to the study of speleothem climate records that complements the suite of analytical instrumentation in the School of Earth Sciences. We have two AP2003 continuous-flow stable isotope ratio mass spectrometers for measuring carbon and oxygen isotope ratios on carbonates (one active, one on standby); a Picarro cavity-ring down isotope analyser for measuring oxygen and hydrogen isotope ratios in waters, and a Nu Instruments "Perspective" dual-inlet isotope ratio mass spectrometer configured to measure small-sample (50 ug) conventional carbon and oxygen isotopes as well as clumped-isotopes (delta-47) on carbonates (sample size ~500 ug). The lab welcomes enquiries from colleagues and their graduate students interested in running samples. Collaborative rates apply (send him an email for a schedule of prices). We are also open to commercial work.
