Fig. 4: Differences between the concurrent estimates of the Florida Current volume transport.
From: Florida Current transport observations reveal four decades of steady state

The differences are computed between the transports estimated from cable measurements (prior to corrections applied in this study) and from (a) dropsonde sections, (b) satellite altimetry measurements, (c) Lowered Acoustic Doppler Current Profiler (LADCP) sections, and (d) the combination of Shipboard and Lowered Acoustic Doppler Current Profilers (SADCP/LADCP) sections. The linear trends of the differences are shown by the red lines.
