Thus, the low temperature and salinity which characterize thesurface waters west of Bermuda (p. 6, 7) were limited to a shallowzone, this being the warmest and saltest area at the 600-meter the very high surface temperature at the mouth of the.

It is clear that thetemperature at this level was highest (12°-13°) northwest of Ber-muda, and that most of the area studied was about 10°, with coolerwater near the coast—i. e., that the general distribution of temper-ature was essentially similar to that of the 600-meter level. But thelow temperatures (about 7°) at stations 10181, 10183, 10185, and10171, suggest a tongue of cold water, extending from southeast to EXPLOEATIONS^ WESTERN ATLANTIC, STEAMER BACHE, 1914. 23 northwest, right across the area traversed by the Bache, whic
