By Sarah Gille, Simon Josey, and Seb Swart: EOS article 13 May 2016 https://eos.org/meeting-reports/new-approaches-for-air-sea-fluxes-in-the-southern-ocean Air-sea exchanges in the Southern Ocean of momentum, heat, freshwater, carbon dioxide, and other gases are not well documented because fluxes are sparsely sampled (see Figure 1) and because high winds, high sea state, and lack of calibration for bulk formulas make Continue Reading

The global oceans are estimated to contribute an impressive 50-85% of the oxygen (O2) present in the earth’s atmosphere. It is often assumed the Amazon and other reputable rainforests are responsible for atmospheric O2, however rainforests only cover 2% of the earth’s total surface area; the oceans cover a remarkable 71%. From the Blue Planet Continue Reading

Written by Sarah Wild for Mail and Guardian 21 August 2015  The stormy waters south of the Cape suck carbon dioxide out of the atmosphere and are key to understanding what will happen to our climate as the Earth heats up. The storms are part of the reason the Southern Ocean is one of the most Continue Reading

In February 2015, Carte Blanche ran a full story on prime time TV covering SOCCO research objectives and how gliders are used in the Southern Ocean to make key observations that assist in answering SOCCOs research questions.

    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

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
