Abstract:
Our ability to reconstruct past conditions of Southern Ocean surface waters is critical to our understanding of the causes of glacial- interglacial differences in atmospheric concentrations of CO2. The extent to which sedimentation of materials (with anomalous isotopic and trace element signatures) produced within sea-ice confounds reconstructions has not been quantified, although it is starting to be recognized as a problem. Detailed study of the behaviour isotope- and trace element-based proxies with carbon and nutrient cycling within sea-ice would be a significant step towards resolving the sea-ice problem and vastly improving proxy-based reconstructions of nutrient cycling in the Southern Ocean over glacial-interglacial cycles.
