East-to-west or west-to-east current linking the eastern and western boundary currents. An example is the North Equatorial Current.

A cross-basin flow that connects the opposite boundary currents is what links the eastern and western sides of a subtropical gyre. The North Equatorial Current moves westward along the equator, carrying surface water from the region near the eastern boundary toward the western boundary. This west-to-east connection across the basin bridges the two boundary currents, which is exactly what a transverse current does. The other terms don’t describe this linking role: a surface current is too general, North Atlantic Deep Water is a deep water mass, and an undercurrent refers to a flow beneath the surface, not the cross-basin link.
