Setting the Southern Ocean in motion: An illustration of the surface currents in the Southern Ocean with the high-resolution ocean model ROMS at 1/8° horizontal resolution. Credit: F. Alexander Haumann, ETH Zurich.



Air-sea difference in pCO2 over the Southern Ocean: A strong oversaturation is visible in winter along the sea-ice edge (grey) when deep carbon-rich waters mix into the surface layer. Blue: undersaturation of the surface ocean with respect to the atmosphere; red: oversaturation. Data stems from the regional ocean model ROMS-BEC that is forced with a climatological surface forcing between 1979 and 2013. Credit: F. Alexander Haumann, ETH Zurich.



Seasonal cycle of the Southern Ocean sea surface salinity: Along the sea-ice edge (grey) a strong decrease in salinity occurs seasonally when the ice melts. Blue: salinity below 34.5 g/kg; red: above 34.5 g/kg. Data stems from the regional ocean model ROMS that is forced with a climatological surface forcing between 1979 and 2013. Credit: F.
