PurposeResearch
ObjectivesAims

1. Undertake an integrated zonal oceanographic transect east of Australia studying the marine biogeochemical cycles of TEIs, as part of Australasia's contribution to the international GEOTRACES program.
2. For the first time, establish the full water column, basin-scale distribution of TEIs (which a specific focus on iron, aluminium, manganese, copper, zinc, cobalt, cadmium), and investigate the role of micronutrient TEIs in the oceans surrounding Australia, and their relationship to environmental and ecosystem conditions.
3. Determine the sources, sinks and fluxes of iron and other TEIs (focussing on atmospheric dust delivery and biomass burning), as well as their transport, solubility and chemical form in the ocean. This includes the use of quasi-conservative elemental tracers of inputs, dissolution and redox cycling.
4. Collect subsamples for subsequent analysis of other GEOTRACES 'key parameters' (such as stable, radioactive and radiogenic isotopes; as listed in Table 2 of the GEOTRACES Science Plan) by international colleagues who are not able to participate in the field program.
