Characterisation of the Antarctic polar frontal zone to the north of South Georgia in summer 1994
PF (and thus the PFZ) is known to be influenced by topographic steering, while local bathymetry has ... 30 days suggested that the surface expression of the PF had shifted southward by approximately 35 km ... . This high-speed flow was found to have a geostrophic component of velocity that was slower than ... estimates for other regions of the PF. Comparisons with output from recent oceanographic models were found ...
