Project title:

What controls the processing, partitioning, and exchange of N-components and isotopes over Antarctic continental shelves?

Project summary:

Nitrous oxide (N2O) is a potent greenhouse gas with a high global warming potential and is the main ozone-depleting substance emitted in the 21st Century. N2O is produced by nitrification, denitrification and is therefore intimately linked to nitrogen (N) cycling. So, it appears important to investigate the impact of the biogeochemical processing of nitrogen in the water column and sea ice, keeping in mind that emission of nitrous oxide, a by-product of the biological pump, will have an opposite effect on climate warming than CO2 sequestration.

Field sites:

Sea ice cores and seawater samples, Antarctica


Nutrient measurements (colorimetry, fluorimetry & chemiluminescence).

Stable isotope tracer experiment (13C & 15N tracers). C & N isotopic composition measurements (EA & GC-IRMS).
