Determination of Sound Speed from Temperature Measurements in the Tongue of the Ocean, Bahamas

摘要

Repeated oceanographic stations in the Tongue of the Ocean have revealed a very stable temperature-salinity (T-S) relationship at depths greater than about 200 meters. Three empirical equations fitted to historical T-S data indicate that temperature observations can be used to compute the associated salinity to within 0.05 0/00 at the 95 percent confidence level. The equations have been tested and verified with recent T-S data; sound speeds derived using computed salinities differ only slightly from those using observed salinities. (Author)
