Research Interests

Biogeochemical applications of atmospheric O₂ and CO₂ measurements as they pertain to the reservoirs of the land biosphere, oceans, and atmosphere; instrument development of land and ocean observing systems for all carbon cycle-related atmospheric gases; use of atmospheric data in regional and global biogeochemical, ocean-atmosphere, and land-atmosphere modelling efforts.


Biography

In 2001, I completed my Ph.D. in Oceanography at Scripps Institution of Oceanography, USA. During my thesis work, I developed the world’s first continuous, high precision atmospheric O₂ analyser and installed it at the remote monitoring site, Baring Head, New Zealand, where it has continued to collect data uninterrupted since 1999. Atmospheric O₂ measurements (together with concurrent CO₂ measurements) are a relatively new and powerful tool for studying the global (and regional) carbon cycle. For example, we are able to partition and quantify the uptake of fossil fuel CO₂ emissions by the oceans and land biosphere, and we are able to monitor changes in the Southern Ocean carbon sink. From 2001-2005, I worked at the Max Planck Institute for Biogeochemistry in Germany, where I was the leader of the “Tall Towers Group”. Here I expanded my work to monitor other greenhouse and greenhouse-related gases such as CH₄, CO, N₂O, and SF₆. We set up multi-species, continuous, automated measurements from very high (up to 300 m) towers in Siberia, Poland, and Germany. Tall tower measurements are a relatively new approach to study regional, terrestrial carbon cycles in continental interiors.

I moved to ENV in 2006 and established the “Carbon Related Atmospheric Measurements” (CRAM) Laboratory as part of LGMAC. With this laboratory, I will bring atmospheric O₂ measurement capability to the UK, as well as an additional suite of gases: CO₂, CH₄, CO, N₂ and SF₆. I am interested in using these measurements to further our understanding of both the terrestrial and oceanic carbon cycles on regional and global scales. I am currently a P.I. in the EU “CarboEurope” (Assessment of the European Terrestrial Carbon Balance, 2004-8) and “CarboOcean” (Marine carbon sources and sinks assessment, 2005-9) projects. Since 2003, I have been leading an international atmospheric O₂ intercomparison programme (GOLLUM), which brings together the 12 international atmospheric O₂ laboratories from around the world in an effort to link our various measurement programmes.
