Closing the mean mass budget of the Florida Straits is fundamental to understanding the source waters of the Gulf Stream and for constraining ocean simulations and forecasts in a region of complex topography. Existing transport time series of the inflow through Yucatan Channel and the outflow at 27°N yield a 9 Sv difference in the mean, which cannot be reconciled by the two minor inflows between. Here we present a synthesis of transport estimates from throughout the Florida Straits, using velocity data collected aboard the cruise ship Explorer of the Seas. Our transports form a consistent mass budget and conform with the northern outflow from the Straits of 32.1-±-3.3 Sv, as measured continuously by cable. In particular, we find an average of 30.0-±-5.3 Sv for the inflow to southern Florida Straits and estimate that Old Bahama Channel contributes less than an additional 2 Sv. Key Points The mean inflow in the southern Florida Straits is estimated at 30.0-±-5.3 Sv The mean transports are consistent from Yucatan Channel to North Florida OBC inflow is less than 2 Sv with eastward flow on top and westward flow below
