- Abstract:
- Iron is an essential nutrient for marine organisms and plays an important role in primary productivity in the ocean and hence the uptake and production of gases associated with climate change such as carbon dioxide. Accurate determinations of iron are therefore required. The low concentration of iron in the ocean (< 1 nM) and the ubiquitous presence of iron in dust and materials (e.g. ships are made from iron) make it hard to undertake measurements without contaminating the samples. Recent developments in clean sampling and analytical land and ship-based methodologies have enabled the acquisition of reliable profiles for the various iron species in seawater. It is widely recognised that a tremendous amount has been learned about the distribution and biogeochemistry of iron in recent years, but the ability to relate one study to another remains problematic. This work proposes the participation in an international intercomparison exercise whereby various top-quality iron research groups will undertake ship-board experiments to determine the best way to take oceanic samples for Fe, to treat and analyse the samples. A great deal of the work will be undertaken at sea, but samples will also be sent out to participating laboratories and analysed using land-based instruments. This rigorous intercomparison exercise will advance our ability to sample and analyse for iron in oceanic waters, to correlate these observations and to distinguish between environmental variability and analytical data quality.
