Annotation
We consider the pattern of species transport in a compound vortex flow contacting with a free surface. The evolution of a compact marker stain (aniline ink or sunflower oil) is traced in spiral arms on the vortex surface created by a uniformly rotating disk in a cylindrical container. The parameters of the structural elements of currents are determined. The geometry of the spiral flow is structurally stable for a wide range of experimental parameters.
