Observing the four dimensional structure and variability of the Southern Ocean using satellite altimetry ...
We present a gravest empirical mode (GEM) projection, of temperature and salinity fields in the Southern Ocean that, combined with satellite altimetry, produces time evolving temperature, salinity and velocity fields, and use these to observe the mean and synoptically varying properties of the South...
