the preceding profile is only fractional, while the surface was more 
uniform, and the mean surface temperature was fractionally higher 
(23.7°) along the Jupiter Inlet than the Cape Florida line (23.04°). 
In the bottom of the channel the water was of practically the same 
temperature (5.7°) and salinity (34.85°/,.) as between Cape Florida 
and Gun Cay, 100 meters deeper.

Fig. 32.—Temperature profile running east from Jupiter Inlet, across the northern end of the Bahama Bank. 
The vertical condensation of salinity and temperature, and the 
general rise of cold fresh bottom water toward the surface from off 
Habana to the northern entrance of the channel is illustrated by an 
artificial profile lengthwise of the axis of the channel (fig. 34), recon- 
structed from the preceding transverse profiles. Several features 
deserve mention. The very warm surface water has been sufficiently 
emphasized. Beneath it lies a band of salter, cooler water (36.5°/o.

ous in both salinity and temperature with the surface water east 
of the Bahama Bank (p. 19, fig. 15, 16). Whether it is also con- 
tinuous with the surface water of the Gulf of Mexico is not certain. 
Finally, at the northern end of the profile the rise of water of 6°-10° 
temperature and 34.8-35°/,, salinity toward the surface is very 
evident; but water colder than 5° does not rise up the slope 
above the 1,100-meter level. Water of this temperature was also
