BIGELOW: COAST WATER EXPLORATION OF 1913.

Station 10071 was considerably the warmest at all depths above 150 

 fathoms of the three stations outside the continental shelf (Figs. 4, 5, 

 6) and presented a fairly typical Atlantic curve; the temperature 

 falling rapidly at first from 76° at the surface to 58.8° at fifty fathoms; 

 then more and more slowly until at the lowest level, 250 fathoms, a 

 reading of 43.6 was obtained. Station 10064 was some 6° colder at the 

 •surface, the diiference gradually decreasing downward; but even at

250 fathoms it was 2° colder (41.6°). Station 10076 was the most 

 southerly of the three, and might, therefore, have been expected to 

 be the warmest, as it lay at about the same relative position on the 

 slope. But as a matter of fact the temperature (49.3°) at 150 fathoms 

 (the deepest reading) was about the same as that of Station 10071 : and 

 above this level, Station 10076 was considerably the colder of the two..
