Our research involves the use of gases, aerosols and isotopocules 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 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 and ocean gliders.

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