Voyage summary

Transit voyage from Darwin to Fremantle to relocate the vessel in preparation for IN2020_V01. During the transit, a number of research, education and outreach projects will be undertaken.

The Chief Scientist on this voyage will lead a project that will use RV Investigator's advanced weather radar as a moving reference point for the Bureau of Meteorology (BoM) operational radar network located along the coast from Darwin to Fremantle. This data will be used to calibrate Australia's operational radar network.

The voyage also includes the following research and outreach projects:

  • Supplementary Cloud Radar, Lidar and Aerosol Measurements (Dr Alain Protat, BoM / Dr Robyn Schofield, University of Melbourne - on shore)
  • Spatial and temporal variability in the distribution and abundance of seabirds (Dr Eric Woehler, Birdlife Australia)
  • Microplastic in the food chain: impact on microbial and planktonic organisms (A/Prof Sophie Leterme, Flinders University - on shore)
  • Continuous plankton recorder tows (Claire Davies, CSIRO - on shore)
  • CSIRO Educator on Board Program (Dr Ben Arthur, CSIRO)
  • MNF Indigenous Time at Sea Scholarship (Hannah McCleary, CSIRO)

The science team on this voyage includes 27 participants from 8 institutions, including two Australian school teachers under the CSIRO Educator on Board Program and the first two university students under the MNF Indigenous Time at Sea Scholarship (ITSS).

This will be the first time the vessel has been at sea over Christmas.

Voyage outcomes

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