A technique for the direct measurement of transport with application to the Straits of Florida

A method is described by which the volume transport per unit width of a water column is obtained from measurements of the run time, depth, and horizontal d efl ection of a freely falling instrument. Measurements of the north-south component of transport in the Straits of Florida using this technique gave 35.5 ± 1.2 x 106 m3/sec on August 16 and 17, 1964. The surface currents and east-west components of transport are also given

Current fine structure in the Florida Current

The current profile to a depth of 120 m has been measured in the Florida Current with a resolution of about 1 m in the vertical. The profile reveals a complex fine structure with regions of high shear

Seasonal variability of the Florida Current

The seasonal variability of the directly measured transport and horizontal currents in the Florida Strait has been determined from 90 transects of the Florida Current at the latitude of Miami, Florida. It is estimated that the seasonal variability accounts for 45% of the total variability in the total transport; the early summertime maximum value of the transport is 33.6 × 106 m3/sec, and the early winter low is 25.4 × 106 m3/sec...

A comparison of direct and electric-current measurements in the Florida Current

Simultaneous measurements of surface velocity obtained in 1967 by means of geomagnetic electrokinetograph and free-instrument techniques aboard two ships in the Florida Current off Ft. Pierce, Florida have been compared . The results show a varying degree of agreement in magnitude across the stream and good agreement in direction. A surprising result is the high seabed conductance

A technique for the direct measurements of ocean currents from aircraft

A method for measuring surface and subsurface ocean currents from aircraft is described. Comparisons of measurements using this technique with those obtained from a ship are given and applications are discussed

Description of a freely dropped instrument for measuring current velocity

A new form of freely dropped instrument for current-velocity measurements is described. Operational procedures for using the instrument and its auxiliary equipment are given
