This study discusses the development of a computer program capable of performing the necessary dynamic computations to obtain estimates of the transports of mass, salt, and heat across the vertical cross section at 40°N within the North Atlantic Ocean. Previous studies have used either different approaches to the problem or, if the same approach was used, then the data were averaged to eliminate seasonal effects. Temperature and salinity data from Crawford Cruise 16, 2 to 22 October 1957 of the International Geophysical Year, are used for the entire cross section of ocean. These observations provide data that are both homogeneous and consistent . General interpolation methods are evaluated for determining the temperature and salinity observations at standard depths. A combination of linear and mean parabolic interpolation methods is found to be the most accurate method of estimating the continuous vertical temperature and salinity, profiles at each station. The velocity estimates are obtained for the cross section by the classical dynamic method. A level of no motion is established where there is a balance of the net transports of mass and salt. Based on this level of no motion, a heat transport figure is obtained that compares favorably with those of earlier studies by Sverdrup, Jung, and Budyko.
