2. University of Bergen current meter system. After Kvinge, 1968 8 



3. Locations of stations and sections for the 1968 International Weddell Sea Oceano- 



graphic Expedition 9 



4. Vertical distribution of temperature (°C) with selected isopycnals (at, in g/1) 



along Section A. Contour intervals are 0.1 °C in the 0.0 to 0.4° C range, 0.5° C in 



the 0.0 to -1.5° C range, and 0.2° C in the -1.5 to 1.7° C range 10 



5. Vertical distribution of salinity (Voo) along Section A. Values less than 34.40Voo 



not contoured. Shading indicates area of sharp salinity gradient (33.331 Voo to 



34.400Vno) 



6. Vertical distribution of density (at, in g'l) along Section A. Values less than 



27.750 g '1 not contoured - 12 



7. Vertical distribution of dissolved oxygen (ml/1) along Section A. Shading indicates 



area of oxygen greater than 8.0 ml/l 13 



8. Vertical distribution of temperature (°C) with selected isopycnals (at in g/1) along 



Section B. Contour intervals are 0.1 °C in the -0.4 to -0.5°C and 0.0 to 0.4°C 

 ranges, 0.2°C in the -1.5 to -1.7°C and -0.4 to 0.0°C ranges and 0.5°C in the 

 -1.5to -0.5° Grange 14
