Voyage summary

Transit voyage from Brisbane to Darwin to relocate the vessel in preparation for IN2019_V06. During the transit, a number of research, education and outreach projects will be undertaken.

The Chief Scientist on this voyage will lead a project to map the seafloor along the Great Barrier Reef continental slope. Four main areas of interest will be mapped to produce 3D imagery of key landslides and canyons in the region. This data will be used to increase our understanding of how and when the Great Barrier Reef formed.

The voyage also includes the following research and outreach projects:

  • First measurements of nitrate isotopic composition in the Coral Sea (Dr Dirk Erler, Southern Cross University)
  • Spatial and temporal variability in the distribution and abundance of seabirds (Dr Eric Woehler, Birdlife Australia)
  • Using the Investigator radar as a moving reference for Australian radar network (Dr Alain Protat, BOM – not onboard)
  • Habitat mapping in Wessel Marine Park (NT) using multibeam sonar and deep towed camera (Dr Rachael Przeslawski, Geoscience Australia)
  • Trichodesmium (filamentous cyanobacteria) sampling (LCDR Matthew Hawker, Royal Australian Navy)
  • AIR-BOX integration and calibration for upcoming voyage IN2019_V06 (Dr Robyn Schofield, University of Melbourne)
  • Deployment of two BGC-Argo floats (Prof Tom Trull, CSIRO – not onboard)
  • CSIRO Educator on Board Program (Dr Ben Arthur, CSIRO – not onboard)

The science team on this voyage includes 34 participants from 16 institutions, including a journalist from ABC News in Darwin and two Australian school teachers under the CSIRO Educator on Board Program.

Voyage outcomes

Summary of voyage outcomes - as well as voyage image gallery - will be published approximately one month after completion of the voyage.
