Volume transport has Deen calculated from USS PURSUIT data above 

 a depth of stability having a sigma-t value of 27.52, which averages 

 920 meters over the entire area. It was felt that this would be more 

 accurate quantitatively than referring the calculations to 1,200 meters, 

 as was done with the dynamic topography, althoxigh the horizontal flow 

 is almost uniform to this depth. At each station, the weighted mean 

 anomaly was calculated referred to the depth at which sigraa-t was equal 

 to 27.52 as read from STD curves. The direction and volume of transport 

 Is shown in figure 9» Total volume transport as calculated is h$ x 

 10^ m3/sec through the area, with an error of 2j$ between incoming and 

 outgoing transport. The presence of Internal tides (inferred by figure 

 lU and discussed under VI. Tidal Influence) may account for the error.

For the most part, the GEK's are in good agreement with the cal- 

 culated transport directions. Where the strong currents in disagree- 

 ment are found, 2 sets, GEK's 25-26 and 27"28, may be explained by 

 winds of 10 to 3J4 knots (high for the time of year) occurring 18 to 

 20 hours earlier. For GEK's 37-38 no simple explanation presents 

 itself, but other observations taken the same day in the sane general 

 area support the calculated transport direction,, Too much importance 

 should not be attached to the discrepancies, however, since it was 

 in this area that the time lag between GEK's and oceanographic sta- 

 tions was greatest.
