Isotopic labelling experiments based on field measurements taken at Signy Island, South Orkney Islands, 2008-2009
Field measurements were used to determine the availability of peptide nitrogen to photosynthetic organisms and soil microbes. In order to fully understand their significance in the Maritime Antarctic nitrogen cycle it was also necessary to examine the ability of organisms to utilise the available peptides. For this reason, isotopically-labelled (15N and 13C) nitrogen compounds, including various peptides, were used to determine their rate of uptake by soil microorganisms and plants. These experiments were carried out on Signy to minimise any changes to organisms during transit.

Methodology:
Microbial uptake was determined by adding labelled solutions to freshly collected soil (n=3) at a rate of 0.35 ml to 0.24 g DW soil followed by centrifugal removal of solution after 30 min at about 7 °C. Microbial uptake was calculated as label in soils after subtraction of label retained abiotically in autoclaved controls.
