Short summary
The paper investigates the role of vertical shear on the horizontal ocean dispersion of tracer particles or concentration fields. We compare in situ measurements to GCM numerical data of the magnitude and the typical timescale of the vertical shear. We discuss how an appropriate sub-grid-scale parameterization can account for an anomalous numerical shear dispersion due to the model poor time resolution. The analysis focuses on the mixing layer, and on the region of the south Mediterranean Sea.
