sounding velocity for either area 13 or 16 should be 

 revised. The shifted boundaries are shown by broken 

 lines of appreciable length, although only a single point 

 is located at each crossing. To show these single points 

 more definitely, lines have been drawn connecting the 

 two oceanographic stations nearest each of these points 

 of intersection. 



As shown in one of the preceding sections (pp. 50-53). 

 correction had to be applied to the sonic depths, owing 

 to error in the timing, by multiplying the computed 

 depths from various parts of the cruise by a constant 

 factor. This has been done and the final values, togeth- 

 er with their positions, are given in table 4 (Oceanogra- 

 phy I -B). 



It is believed that, except where otherwise noted in 

 this table, the soundings are accurate within the follow- 

 ing limits: soundings to 360 inclusive, +1.0 per cent; 

 soundings 361 to 476 inclusive, +1.5 per cent; soundings 

 477 to 534 inclusive, +1.0 per cent; and soundings 535 

 to 1496 inclusive, +0.5 per cent. 



The sonic soundings listed in table 4 (Oceanography 

 I-B) are nearly all shown graphically in twenty-eight 

 bottom profiles, of which twelve have been plotted 

 against latitude and sixteen have been plotted against 

 longitude. The course followed by the Carnegie has 

 been shown on each profile.
