has a powerful influence on Earth’s climate, as it stores more anthropogenic CO2 and heat than any other latitude band on Earth. This massive body of water also plays a pivotal ecosystem role in regulating the supply of nutrients to lower latitudes which supports about 80% of ocean production. Its ability to continue to provide Continue Reading

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

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
