Stable Isotope Lab

Bio

Reid is eager to probe knowledge gaps regarding Earth system response during periods of abrupt climate change, both in the modern and across geologic time.

Reid collaborates with a small team of professional researchers to routinely diagnose, troubleshoot, and repair a fleet of dual-inlet and continuous flow isotope-ratio mass spectrometers to produce accurate and precise datasets for ~15,000 air samples annually.  The carbon and oxygen isotope measurements of atmospheric carbon dioxide and methane are used in a 30+ year partnership between INSTAAR and the Global Greenhouse Gas Reference Network at NOAA to study the sources and sinks in the modern-day carbon cycle. 

Prior to his time at INSTAAR, he worked in a team of researchers investigating marine sediment paleoclimate archives as analogs to modern-day anthropogenic climate change.  He utilized inductively coupled plasma mass spectrometry and scanning electron microscopy of foraminifera to infer past changes in ocean temperature, acidity, and salinity due to large-scale carbon cycle perturbations during the early Eocene.   

Reid is eager to probe knowledge gaps regarding Earth system response during periods of abrupt climate change, both in the modern and across geologic time. His research specialties include the measurement and analysis of stable isotopes of atmospheric methane using gas chromatography combustion isotope ratio mass spectrometry.
