Data from three moored current meters and four inverted echo sounders deployed south off Shikoku, Japan during October 1993 through November 1995 were used to investigate the variations of velocity and transport associated with coastal cyclonic eddies. The averages of the velocity near the bottom across the ASUKA line were about 5 cm/s for southwest on the continental slope, The vertical profiles of the geostrophic velocity were nearly barotropic at two coastal current meter stations when the coastal cyclonic eddies passed through the ASUKA line. Directions of the velocity anomaly near the bottom were then southwest at the most coastal station and northeast at the two relatively offshore stations. Variations of the barotropic transport anomaly associated with the coastal cyclonic eddies and the decrease of the geostrophic transport anomaly associated with southward shift of the Kuroshio axis were seen simultaneously.59
