Short summary
A novel analysis is performed utilizing ocean current kinetic energy computed from from along-track satellite altimetry data from 1993 to 2015. The position of enhanced kinetic energy is used to detect shifts in frontal positions in the Southern Ocean. Results indicate no significant shift in the front positions across the Southern Ocean, on average, although there are some localized, large movements, both north and south.
