encountered at about this same level east of the Bahamas and also 

 in the Providence Chamiel (station 10196). 



The distribution of temperature and salinity may be further 

 illustrated by charts of the 200, 400, and 600 meter levels. 



At 200 meters (fig. 35) there was a general rise of temperature 

 from north and west to south and east from about 10° close to the 

 coast of Florida to 23° off Habana and 21.8° off Gun Cay. Opposite 

 Jupiter Inlet, however, the warmest water (20.13°) was in the center 

 of the channel at this level, with a fractionally lower reading (19.93°) 

 off the northern end of the Bahama Bank. The range of salinity at

this level was only 1.37Voo (35.3 to 36.67Voo) with the water freshest 

 close to the coast of Florida, while the salinity of the southern and 

 eastern half of the channel ranged from 36.5 to 36.67«/oo (fig. 36). 



At 400 meters (fig. 37) there was a general west to east warming 

 in the northern half of the channel from about 9° near Florida to 

 16° near the Bahama Bank; but off Key West this was complicated 

 by the warm tongue of 17° in the center of the channel, already 

 described for the Key West-Habana profile. At this level the range 

 of salinity (fig. 38) was from 35.1Voo (station 10206) to 36.2Voo; 

 lowest close to the coast of Florida, highest on the south and
