Instrumentation expert in stable isotope mass spectrometry.
I work on several projects within INSTAAR's Stable Isotope Lab.
In collaboration with NOAA's Global Monitoring Division, I work to characterize the stable isotopic composition of carbon dioxide and methane from locations around the world. We use this information to better constrain the sources and sinks of these greenhouse gases in atmospheric models. These models in turn give us one of our best chances to understand climate change as it changes our world.
I also help run SIL's drone program where I use a fixed wing drone flying up to 1600m to sample water vapor isotopic values at the EGRIP ice core camp in Northern Greenland. Water vapor isotopes above and below the planetary boundary layer at altitude informs us of the entrainment of incoming weather systems to the ice sheet and helps us hone in on the uncertainty of future mass-balance. The atmosphere talks to the ice sheet and the ice sheet has something to say back.
Lastily I work with our collaborators at the Sante Fe Institute on implementing the complexity metric weighted permutation entropy in order to characterize the flow of information in ice core records. Combined with contextual ice information, we hope to use this modern analytical technique to inform us on the climate system and to help find potential new places for bulk climate shift.
