The subpolar sector of the Southern Ocean plays an important role in the global carbon budget. However, while, researchers have linked the occurrence of widespread outgassing of CO2 in this region to the large-scale upwelling of old CO2-rich deep waters, the mechanisms that explain their transport into the surface mixed-layer, where it can then be outgassed into the atmosphere, remain poorly understood.
In the study, the researchers highlight the importance of the frequent strong storms in modulating the mean seasonal transport of CO2 within and across the mixed-layer and surface ocean boundary interfaces.
The CSIR has developed a polymer composite solution for one of Africa’s largest steel pipe manufacturers, Hall Longmore, which takes them one step closer to offering the South African water industry a localised push-fit application for pressurised steel pipelines.
Using the DSI-CSIR Nanomaterials Industrial Development Facility, CSIR researchers developed a uniquely formulated polymer composite material for the steel pipe manufacturer and performed coating trials at their facility.
“The coating trials proved to be a success and an indication of a fruitful collaboration between local institutions working together to localise technology solutions for industry,” says Managing Director of Hall Longmore, KC Van Rooyen.

CSIR senior researcher Dr Thomas Ryan-Keogh and CSIR research group leader for the Southern Ocean Carbon-Climate Observatory Dr Sandy Thomalla are co-lead authors of this high-impact research, which suggests that there may be a reduction in the supply of iron to the Southern Ocean’s surface sunlit waters.
Outlining the significance of the research, Ryan-Keogh says that the Southern Ocean is a globally important region that helps to mitigate the impacts of climate change by absorbing, mainly through physical processes, a significant proportion of the man-made carbon dioxide that is emitted through the burning of fossil fuels. “Almost half of all the anthropogenic carbon dioxide that dissolves in the ocean does so here,” he says.
