. Explorations of the United States Coast and Geodetic Survey steamer "Bache" in the western Atlantic, January-March, 1914, under the direction of the United States, Bureau of Fisheries : oceanography. the line running southwest from Bermuda (fig. 13) thesurface layers grew gradually warmer toward the south, the curvefor 15° dipping from 550 to 700 meters, while near the surface the EXPLORATIONS, WESTERN ATLANTIC, STEAMER BACHE, 1914. 17 temperature rose from about 18° to 20°, and the peculiar S-shapedcurve for 20° suggests an active mixing of cool and warm surfacewater. In the deeps, below 700 meters, the curves reveal a pro-nounced upwelling of cold abyssal water at station 10181, and thesahnity profile (fig. 14) along this line shows much the same thing,the surface layers down growing Salter, from north to south, while inthe deeper layers salinity, like temperature, curves rise at stationlOlSl. The temperature profile from Florida to a point 200 miles southwestof Bermuda (fig. 15) shows that water warmer than 20° was thickestnear the Bahama Bank (about 200 meters). East of this the curveof 20° rises to 50 meters at station 10191, then dips, as a tongue, to Stations. -Temperature profile of the upper 1,800 meters from Chesapeake Bay to station 10161; and from:point 130 miles south of the latter to Bermuda. 150 meters at station 10189, where the surface was °. But 20°water is again seen at the eastern end of the profile. The curves for15°, 10°, and 5° are roughly parallel with each other, showing a suc-cession of cold and warm undulations, but, as a whole, dipping fromwest to east, the former from about 500 to about 700 meters, thelatter from about 1,100 to about 1,600 meters. The most strikingof these undulations is a well-developed cold band some 300 milessouthwest of Bermuda (station 10185), and this is evidenced by anupswing of the curves down to 1,800 meters, as well as by loweredsurface temperature.
