Figure 3.-Vertical distributions of meridional geostrophic velocity (cm/s) through Standard Section A-7 computed relative to the 

 1,000-decibar surface. Net transport values given in Sverdrups (1 SV = 10" mVs). Station numbers are arrayed along the upper 

 horizontal boundary. Positive velocities are northward. 



The vertical sections of geostrophic velocity 

 (Figure 3) revealed a fairly consistent pattern of 

 alternate bands of weak (<10 cm/s) northward 

 and southward flow in the offshore half of the 

 transect (seaward 400-500 km). West of this, a 

 narrow band of stronger (10-40 cm/s) northward 

 current was found in five of the sections, located 

 generally just seaward of the 1,000-fathom 

 isobath, about where the band of stronger north- 

 ward Antilles Current was shown by Boisvert 

 (1967). However, a band of southward flow of 

 about the same speed was found nearby in each of 

 the transects. Net transport through the section 

 was northward in four of the occupations and 



southward in two, ranging from 3.9 to 30.4 x 10^ 

 m^/s northward and 3.4 to 6.4x10^ mVs south- 

 ward. The mean net transport for the six sections 

 was 8.6 X lO^m^/s northward. In five of the sec- 

 tions, the northward transport values fall far short 

 of the 30x10^ m^/s or more which the Antilles 

 Current is supposed to add to the Gulf Stream, 

 indicating that sources other than the Antilles 

 Current must contribute to the observed increase. 

 Although it is difficult to make a direct com- 

 parison with Kort's findings (Kort 1972), because 

 of the small size of his charts, paucity of data 

 portrayed, and the fact that all of his data were 

 collected south of lat. 28° 35'N, the locations of the
