Our research focuses on the use of gases, aerosols and their isotoplogues to understand present and past biogeochemical and physical processes in the atmosphere and oceans.

Our vision follows an interdisciplinary approach, integrating chemistry, biology and physics, and comprises several overarching goals:

  • to understand and quantify chemistry and oxidation capacity of the atmosphere
  • to quantify relative time scales of transport and biogeochemical conversion processes in atmosphere and oceans
  • to understand and quantify variability in marine biological production and CO2 uptake down to small spatial scales
  • to gauge the impact of human activities on greenhouse gas emissions in terrestrial and coastal environments

To achieve these goals, we use field measurements, laboratory experiments, theoretical considerations and numerical modelling. We develop high-precision analytical methods using a range of scientific instruments, for example, isotope ratio mass spectrometers, cavity ring-down greenhouse gas analysers or ocean gliders.

You can find out more about what we are doing on these pages, in our publications or by contacting us by > email.

We offer nitrogen (15N/14N) and oxygen (18O/16O, 17O/16O) isotopic analyses of nitrate (NO3) as analytical service, see here for more information.
