FRONTS AND UPPER OCEAN THERMAL VARIABILITY SOUTH OF NEW ZEALAND
The structure and variability of Southern Ocean fronts south of New Zealand are described based on fifteen summer expendable bathythermograph (XBT) sections obtained between 1994 and 2001. The temperature variability north of 60°S is dominated by meanders and meridional shifts of the Sub-Antarctic F...
