1. Collect samples to characterise the diversity and function of microbial communities in the relatively warm EAC, against the relatively cool water of the Tasman Sea and adjacent shelf waters.
2. Conduct perturbation experiments to experimentally test the role of temperature and nutrients (particularly N and Fe) in microbially mediated biogeochemical transformations.
3. Assess the links between microbial biomass, size structure and carbon production with higher trophic levels (zooplankton, micronekton and cetaceans-seabirds) in a frontal eddy(ies) relative to adjacent shelf and EAC waters through coordinated sampling.
4. Sample sediments to examine water-sediment geochemical processes and historical record of plankton.
5. Sample aerosols to study natural iron fertilisation of oceans around Australia (Supplementary Project).
