current field variation during this time. The accumulation of distortion of the barotropic component of the current and the barotropic transport corresponding to it
can be, in principle, estimated from the satellite altimetry. A distortion constituent
of the barotropic transport, which is not taken into account using these data, also
exists. This constituent is related to the displacement of isohypses (streamlines of
the geostrophic current at the ocean surface) relative to the isobaths. Due to this
displacement during the execution of the section, the instantaneous barotropic
transport varies within certain limits. It is clear that, depending on the restriction on
the total transport across the section, this variability should be completely or partially compensated by a change in the instantaneous baroclinic transport. The latter
cannot be accounted directly from the satellite altimetry data. Note that the
