The Centre for Southern Hemisphere Oceans Research brings together researchers from Australia and China to further scientific understanding of the southern hemisphere oceans and their role in global and regional climate.

The challenge

Understanding the complexities of the southern oceans

More than 80 per cent of the Southern Hemisphere is covered in oceans and until very recently these vast oceans were largely unmeasured and poorly understood.

We do know that the southern oceans play a critical role in the global climate system through; absorbing more heat and carbon dioxide than any other ocean region; influencing cycles of floods and droughts; and, controlling the fate of the Antarctic Ice Sheet and its contribution to sea level rise.

Our response

A new centre to deepen knowledge on climate and oceans

To develop a deeper understanding of the role of southern oceans in the global climate system CSIRO has collaborated to create the $20 million Centre for Southern Hemisphere Oceans Research (CSHOR).

Together with the Qingdao National Laboratory for Marine Science and Technology (QNLM) and university partners the University of New South Wales and the University of Tasmania, the new Centre will conduct fundamental research on the ocean's role in a changing climate.

The Centre, based in Hobart, will conduct research to improve our understanding of the complex nature of the climate system, leading to information, products and services to assist Australia, China and the world to better manage the impacts of climate variability and climate change.

The Centre builds on CSIRO's strong history of research leadership in the southern hemisphere oceans, and on our long history of international collaboration, including over 40 years of collaboration with China.

Steve Rintoul: We’ve got some difficult decisions to make in society.  We need to decide how we’re going to respond to the challenge of climate change and how we’re going to adapt to both natural climate variability and the climate change that we don’t manage to avoid.

And the key to doing that is knowing exactly what’s going to unfold in the future as climate changes and as the modes of natural climate variability respond to that climate change.

Ming Feng: CSHOR is important because it brings together the Chinese and Australian scientists

to tackle the most crucial questions for the world ocean climate. 

[Image changes to show Prof Matthew England talking to the camera and text appears: Prof Matthew England, CSHOR Project Leader, University of New South Wales]

Prof Matthew England:  The Southern Ocean is poorly sampled.  It’s poorly represented in models that we use to predict the climate system and it’s poorly understood because of this lack of observations and models in the region.

So CSHOR’s filling this very important niche to get at the Southern Ocean climate system, how the oceans are warming and what the implications are for climate change.

Ming Feng:  So, CSHOR project will help us to use a cost effective, robotic technology to mirror the upper ocean and the copying between the upper ocean and the atmosphere which may lead to further development of the robotic technology to apply in other ocean regions.

Susan Wijffels: CSHOR is going to interact a lot with big, international campaigns. It’s going to help us understand how to build the new observing system for the ocean and how to evolve that and also some of the projects that we’re building in CSHOR have already entrained a lot of international collaborators.

Xuebin Zhang: The CSHOR is a purely scientific uni, science orientated.  So, it’s very important.

So even to… we got to address some of the cutting edge of scientific questions in the ocean and the climate and the model where it brings expertise from Qing LM and the CSIRO and UNSW the UTas.

[Image changes to show Steve Rintoul talking to the camera]

Steve Rintoul: CSIRO is important because it gives us the means to tackle some of the biggest open questions in the southern hemisphere ocean science.

The results

Answering fundamental questions to improve climate response

Research will be undertaken across a number of key projects, answering the following fundamental questions about the southern oceans' role in future climate:

  • How will the El Nino – La Nina cycles that bring floods and drought to Australia will change with climate change?
  • How will changes in the ocean, including interaction with Antarctic ice shelves, impact sea level rise?
  • What is the role of the Indian Ocean Dipole and the Southern Annual Mode in the future climate?
  • What role will southern oceans play in future distribution of heat and carbon dioxide across the planet?
  • How do the oceans north of Australia influence regional and global climate, and how will these regions change in the future?

CSHOR's research will underpin the next generation of climate projections needed to inform effective responses to climate change and variability. The research will be made publicly available and will contribute to Australian, Chinese and global efforts to effectively anticipate and adapt to future change.

The Centre for Southern Hemisphere Ocean Research opened in May 2017
