A new mathematical model for the transport across a meandering current like the Gulf Stream is suggested. This model is based on a modification of the von Kármán vortex street stream function. The suggested modification allows one to approximate the main patterns in meandering ocean currents as observed by satellites. The inclusion of small perturbations in time (as periodic functions) and in space (in the form of weak eddies) enhance transport and mixing across the current. The mixing across the current is examined by following the deformation of certain well-defined (circular) areas on one side of the current back in time, so that we can determine from which initial part of the current that area is eventually composed.
