Comparisons between Patterns of Sea-Surface Temperature and Sub-Surface Parameters in the Western Tasman Sea

摘要

Comparisons are presented between patterns of sea-surface temperature, temperature at 250m, mixed-layer depth and dynamic height for the western Tasman Sea. Data are from ship cruises and aerial surveys. It is shown by comparing deep current structures, shown by the temperature fields at 250 metres and/or dynamic heights, with surface temperature patterns that on many occasions the latter revealed the East Australian Current flowing down the coastline, turning eastwards between 30 deg and 32 deg S and, sometimes, turning back to the north. Also on most occasions in winter and spring, and sometimes in summer-autumn, warm-core eddies were apparent in surface temperature patterns. In general, surface mixed-layers are deeper above anticyclonic features and shallower above cyclonic features.
