Circulation of the Southern Ocean

A remarkably detailed animation of the movement of the densest and coldest water in the world around Antarctica has been produced using data generated on Australia’s most powerful supercomputer, Raijin.

This animation has revealed underwater ocean storms generated by eddies, waterfalls of cold dense water that plummet two kilometers off the Antarctic Continental Shelf into the abyss and underwater waves hundreds of meters high.

Chief Investigator, Dr Andy Hogg, from the ANU hub of ARC Centre of Excellence for Climate System Science worked with the National Computational Infrastructure’s VizLab team, using a high-resolution ocean model, to produce the animation.
