- Assess the sources of external iron to the southern extension of the EAC
- Compare and contrast the biogeochemistry of EAC waters with HNLC waters located southwest of Tasmania
- Determine the role of 'new' (externally sourced iron) versus 'recycled' iron in regulating springtime productivity across the STF
- Test the sensitivity of neodymium and thorium isotope sedimentary records to local sedimentary processes

The primary objective of the voyage is to characterise the sources and biogeochemical cycling of iron and associated nutrients and their impact on productivity southwest, southeast and northeast of Tasmania.
