Abstract
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.
