Over the northern end of the Bahama Bank the ^/oowater is overlaid by fresher water, as described for the JupiterInlet profile across the Florida current (p. 32). Below 1,200 metersthere is very httle further decrease in salinity: At 1,800 meters itranges from to only, and judging from what isknown of Atlantic bottom water (Murray and Hjort, 1912; Nansen,1912), it is probably practically uniform below that depth. Thoughthe curve of 35^/oo suggests a shght upwelUng of this abyssalwater in the center of the profile, the entire range of variation of Stations179 181.
