Welcome aboard MISO!


The MISO voyage on CSIRO research vessel RV Investigator sailed from Hobart on 5 January 2024.

MISO stands for:
Multidisciplinary Investigations of the Southern Ocean.

The aim of the 60-day voyage is to improve our ability to anticipate the impacts of future climate change.

39 scientists in five teams (CTD, Carbon, Atmosphere, Biology, GEOTRACES) will explore how links between physics, biogeochemistry, plankton, aerosols, precipitation and clouds influence the Earth’s climate, from the deep ocean to the lower atmosphere.

The Southern Ocean takes up vast amounts of heat and carbon dioxide and acts as a climate 'shock absorber'.

Changes in the Southern Ocean would have profound implications, influencing the rate of climate change, the productivity of the Antarctic ecosystem, and the future of the Antarctic Ice Sheet. 

Data collected on the MISO voyage will be compared to earlier measurements to track how the Southern Ocean is changing and what it means for climate and sea level rise.


The MISO voyage is a key research activity of the Australian Antarctic Program Partnership (AAPP). The AAPP is funded by the Australian Government through the Antarctic Science Collaboration Initiative to better understand the role of the Antarctic region in the global climate system and the implications for marine ecosystems. The AAPP is a 10-year program established in July 2019 and is led by the University of Tasmania (UTAS) with core partners the Australian Antarctic Division (AAD), CSIRO, and the Bureau of Meteorology (BoM). A number of scientists on the voyage are also part of the ARC-funded Australian Centre of Excellence for Antarctic Science (ACEAS), based at UTAS.

This research is supported by a grant of sea time on RV Investigator from the CSIRO Marine National Facility which is supported by the Australian Government’s National Collaborative Research Infrastructure Strategy (NCRIS).
