Niiler and Richardson (1973) have presented the results of direct measurements showing the seasonal variation of the volume flux of the Florida Current, from the average low of 25.4 × 106 m3/s in about November to the average high of 33.6 × 106 m3/s in about June. These excellent measurements give us, for the first time, reliable quantitative information about the seasonal variation of a major ocean current.
