Oceanography. GENERAL BIOLOGY 695 is situated in the Sargasso Sea, Station 86 on our northern track, Station 101 to the south of, and Station 113 to the north of, the Wyville Thomson Ridge, while Station 46 from the year 1900 is west of the Lofotens. Figs. 504 and 505 show that just on the verge between the two seas, between Stations 101 and 113, a marked drop occurs in the temperature and specific gravity. In

A specific gravity of does not occur in the Atlantic at all at the depths here treated of, while the entire deep layer in the Norwegian Sea is of a specific gravity even higher than In the Atlantic the fall away towards deep water and as we approach the tropics. In the Sargasso Sea we find the same specific gravity at 600 or 800 metres as occurs in the Norwegian Sea at 50 metres.
