A changing climate has brought the Southern Ocean into sharp focus, not only due to the physical changes we are observing in the ice levels and sea surface temperatures around Antarctica, and their effect on currents, but on the biology and life within the oceans. When sailing across the oceans, you notice their Continue Reading

CO2 is a greenhouse gas which means that it absorbs outgoing long wave radiation and in so doing warms the atmosphere. Of the approximately 3 billion tonnes of CO pumped into the atmosphere annually by human activities, about half stays there, warming the planet through the greenhouse effect. The rest is soaked up by natural processes, more-or-less Continue Reading

They are heading out past the breakwater to deploy this wave glider, which will begin its month-long journey to the Southern Ocean, and they are racing against the oncoming storm. These storms are part of the reason that the Southern Ocean is one of the most under-researched in the world, even though it absorbs almost Continue Reading

Their previous long term mission, the Southern Ocean Seasonal Cycle Experiment (SOSCEx, Swart et al., 2012) was conducted between September 2012 and March 2013, when five state-of-the-art autonomous Seagliders were deployed in the Southern Ocean from aboard South Africa’s newest polar ship, the SA Agulhas II. The gliders observed the SAZ region of the SE Continue Reading

This voyage combined the annual transportation of relief and logistics supplies, and the ferrying of the SANAE over-wintering team to South Africa’s Antarctic base, with the Southern Ocean Carbon Climate Observatory (SOCCO) research programme led by the CSIR. According to CSIR ocean systems and climate chief scientist and head of the SOCCO programme, Dr Pedro Continue Reading
