The depth of the column, h, was approximated as 5,000 meters, and geopotential 

 anomalies from the station data were referred to the same depth. Observations ex- 

 tended to at least 5,000 meters at most of the stations used in the program; at stations where 

 they did not, values of temperature and salinity were selected to extend the profiles to 

 5,000 meters. These values were selected by extrapolating profiles at the station con- 

 sidered and by interpolating between appropriate values at adjacent stations. In the 

 selection care was taken to avoid creating artificial structure in the water mass. 



Values of the wind-driven transport, geopotential anomalies referred to 5,000 meters, 

 the distance between stations, and the reciprocal of the Coriolis parameter are submitted 

 to a second program. This program calculates velocities and geopotential anomalies 

 at each standard depth. These velocities and anomalies reflect the variation with depth 

 associated with the structure of the water column and are adjusted to describe a trans- 

 port through the section equal to the geostrophic mode of transport from the curl of wind 

 stress — that is, equations (36a, b) are satisfied. Tables 2 through 5 show the data printouts 

 from this program for the four sections considered. An explanation of the quantities 

 shown in the headings and columns of each table follows. 



Quantities in the headings are: 



STATIONS, identifying numbers of oceanographic stations 



L, length of section in kilometers 



COR, reciprocal of the Coriolis parameter, multiplied by 10~ 5 



TRANSPORT, the wind-driven geostrophic transport in 10 4 m 3 /second 



N, the number of standard depths considered 



SUMVZ, transport in 10 4 m 3 /second as obtained from differences of dynamic heights, 



referred to 5,000 meters; the sum of the values in column VVZ below 

 CORR, a correction factor in volume transport per meter of depth in 10 2 m 2 /second, 



obtained by:

SUMVZ*, a check of computations. The value is identical with that for TRANSPORT. 

 Quantities in the columns are: 

 DEPTH, standard depths 



A, geopotential anomalies in dynamic meters for station A, referred to 5,000 meters; 

 station A is the southern station of meridional sections and the eastern station of 

 the pairs along parallels of latitude. 



B, geopotential anomalies for station B 



C, the difference, column A minus column B at each standard depth 



VZ, volume transport per meter of depth in 10 2 m 2 /second applicable to each depth. 

 This function of volume transport is obtained by multiplying the difference in geo- 

 potential anomalies (column C) by the reciprocal of the Coriolis parameter (COR in 

 heading). 



VVZ, baroclinic transport in 10 4 m 3 /second for each depth interval, obtained by 

 numerical integration of VZ with respect to depth 



VCZ, an adjusted volume per second per meter of depth applicable to each depth. 

 VCZ is obtained by adding VZ at each depth to the correction, CORR, as given in 

 the heading of the table. 



V*, the velocity at each standard depth corresponding to the adjusted transport values, 

 VCZ. These velocities, obtained in cm/second, are the absolute geostrophic
