Linking Australians to their heritage
CSIRO research vessel (RV) Investigator, part of the Marine National Facility (MNF), offers a highly flexible platform that can accommodate multiple research projects on a single voyage. In providing this unique service, the MNF is helping to uncover our maritime heritage alongside other crucial research, such as mapping the seafloor in our region.
The problem
The MV Blythe Star, a 44-metre freighter that disappeared off the coast of Tasmania in 1973, is one of an estimated 8,000 shipwrecks around the Australian coastline. These vessels hold immeasurable stories of the trials and tragedies of living on an island continent. Locating and protecting underwater cultural heritage is a significant challenge that requires specialised equipment, unique expertise, and time.
By facilitating a ‘piggyback’ project on a research voyage off southwest Tasmania in April 2023, RV Investigator was able to confirm the final resting place of MV Blythe Star.
The solution
RV Investigator is equipped with shallow, mid-water and full ocean depth seafloor mapping systems and specialised underwater camera systems. Following a systematic survey of a wreck (pinpointed by local fishing vessels and a previous sea floor survey) and visual inspection with two underwater camera systems, data and vision collected by the CSIRO project team confirmed the identity of the MV Blythe Star. This ended a 50-year mystery and brought closure to a community that included the last remaining survivor from the tragedy.
The impact
While often additional to primary voyage objectives, the unique capability for locating shipwrecks and other underwater cultural heritage work demonstrates the significant benefit that RV Investigator delivers for Australia. We are proud to contribute to the protection and preservation of our maritime heritage, with such discoveries providing closure, connecting communities, and bringing families back together.
