Oceanographic conditions were examined along two meridional sections of 150 and 115°E in the Australasian sector of the Southern Ocean during the summer of 1983-84. Three major oceanic fronts were identified in these sections, i.e., the Subtropical Convergence, the Subantarctic Front and the Polar Front. The vertical features of these fronts were identified by temperature, salinity, dissolved oxygen and some nutrient salts. The Subtropical Convergence was at 47°S along 150°E and 43.5°S along 115°E. The Subantarctic Front was at 49°S along 150°E and 47.5°S along 115°E. The Polar Front was at 56.5°S along 150°E and 55°S along 115°E. The geostrophic flow relative to 2000db was calculated for both sections. The maximum valocity was 18cm/s at the surface between 45 and 47.5°S along 115°E. The direction of the flow was mainly eastward for both sections. The volume transport was about 88×(10)^6m^3/s between 45 and 65°S along 150°E and 105×(10)^6m^3/s between 40 and 65°S along 115°E.
