Wave height data from Geosat over the period November 1986 to February 1989 were used to survey the occurrence of wave amplification/attenuation in the southwest Indian Ocean. More than half of the wave profiles that were inspected revealed some enhancement in the Agulhas Current, with 17% of the profiles showing fractional amplification of more than 40% (relative to the background wave height). Other aspects that were considered included attenuation of wave height in the shelf region and the characterization of the Agulhas Return Current by wave height variations. ¿ American Geophysical Union 1994
