The Southern Ocean is a key component of the earth system, being responsible for 50% of ocean uptake of atmospheric CO2 and 30% of carbon export flux to the deep ocean. Introduction Climate models and decadal data sets predict changes in the Earth’s climate that will influence the effectiveness of the Southern Ocean CO2 sink 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

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
