of overlap between South Atlantic Central Water and North Atlantic 

 Deep Water that has a low temperature and a relatively high salinity. 

 Captures that were made around 1000 m in the South Atlantic Central 

 Water come from the Antarctic Intermediate Water that penetrates 

 well northward at those depths. The shallow captures fall within the 

 South Atlantic Central Water Mass envelope where the temperature 

 is high (6°-7.5° C) and the salinity is relatively low (34.50-34.65%o). 

 The plots of the captures on vertical sections constructed for the 

 eastern and western Atlantic show the location of B. ahyssicola in 

 relation to temperature, salinity, and oxygen concentration (figs. 52- 

 59). Only one juvenile specimen was taken in the eastern Atlantic at 

 a temperature above 10° ; the remaining captures were in less than 10° 

 water and most of these were below the 5° isotherm (figs. 52-54A). 

 The distribution with salinity shows that B. ahyssicola tends to occur 

 in waters where the salinity is al)Ovc o4:.50%o but below 35.00%o (figs. 

 55, 56, and 54B) ; in the North and South Atlantic Central Water 

 Masses the values correspond principally to Antarctic Intermediate
