Deep Structure of the East Australian Current and Tasman Front
Abstract
In order to investigate the deep structure of the East Australian Current and the Tasman Front, surface to bottom Conductivity-Temperature-Depth (CTD) casts were obtained along various sections through them on eight different research cruises. From this data set it was found that the depth to which these major oceanographic features extended was highly variable, lying between 2500 m and 4500 m. It was found that any flow below 1500 m in the Tasman Front was blocked from flowing eastward firstly by the Dampier Ridge and then by the Lord Howe Rise, and so flowed either north or south, depending on the orientation of the near-surface flow. On many sections, at abyssal depths, near-bottom bodies of water were found with temperatures approximately 0.05 C lower than their surroundings and with widths and depths of order 50 km and 600 m respectively. Keywords: Australia.
