The RV Investigator, the RV Southern Surveyor replacement ship, was delivered in 2014 and is instrumented to collect biogeochemical data. It operates from the tropics to the ice edge.  

The, SRV Aurora Australis, is an ice breaker used for research and resupply. The vessel was instrumented for underway CO2 measurements in January 2011 and continues to provide data.

The Tangaroa underway CO2 system was installed in February 2013 and continues to provide data streams. The addition of the Tangaroa to the CO2 ship of opportunity program will substantially improve coverage in the Australia-New Zealand region and in the Southern Ocean.

The Antarctic re-supply vessel, l’Astrolabe is one of the few vessels with a repeat track in the Southern Ocean, operating between Hobart and the French Antarctic base, Durmont d’Urville. l’Astrolabe was fitted with biogeochemical sensors in Oct 2010, providing data until March 2013.

In addition, CO2 data collected as part of the FutureReef MAP project, a three-year project designed to monitor ocean chemistry along the entire length of the Great Barrier Reef is available via the AODN. The Future Reef MAP project is funded by Rio Tinto Alcan and administered by the Great Barrier Reef Foundation, with co-investment by CSIRO. The project is the first large-scale CO2 observing system established on the Great Barrier Reef using the Rio Tinto ship, RTM Wakmatha. This dataset contains quality controlled underway measurements of the fugacity of CO2, atmospheric pressure, and sea surface temperature and salinity. The data management and distribution of these data were supported by the CSIRO Carbon Collaboration Cluster and the Australian Coastal Ecosystem Facility.
