Note
As part of the SFERPM Program we have made direct measurements of volume transports in the major passages of the middle Keys over semidiurnal tidal periods usinga RDI 600 kHz shipboard ADCP with 201 beam angle. Transects were made perpendicular to the passages on six occasions at LongKey Channel, Channel 5 and Channel 2 and on a single day at 7-Mile Bridge.
