colder on the surface, warmer on the bottom, from Cape Ann toward 
the Bay of Fundy, for example the surface and fifty fathom tempera- 
tures were 64° and 41.05° at Station 10105; 61° and 44° at Station 
10103; 54° and 47.5° at Station 10101. And though this change was 
interrupted off Mt. Desert (Station 10099), the difference between 
surface (50.5°) and bottom (48.3°) off the Grand Manan Channel (Sta- 
tion 10098) was only 2°. 
At Stations 10097 and 10100 the temperature agreed at the surface 
(55°) and at 100 fathoms (43.2°); but from about ten fathoms down 
to about fifty fathoms, Station 10100 was the colder of the two, 
with a difference of 3° at twenty fathoms, a fact probably due to an 
upwelling of cold water from below. 
On the Nova Scotia slope, off Lurcher Shoal (Station 10096), the 
temperature curve (Fig. 19) agrees very closely with that for Station

Fic. 19.— Temperature sections in the Gulf of Maine, on Jeffrey’s Bank 
(Station 10091); off Matinicus Island (Station 10101); off the coast of 
Maine near the Grand Manan Channel (Station 10098); near Lurcher 
Shoal (Station 10096); and on German Bank (Station 10095). 
10097 from the surface down to fifty fathoms, cooling from 54° to 
about 47°, and although the seventy fathom reading (43°) was colder 
than the water at the corresponding level in the northern part of the 
basin, it was almost precisely the same as the bottom water there 
(Stations 10097 and 10100). The temperature was practically uniform 
from the surface downward, on German Bank; and even over the 
seventy fathom curve on its western slope (Station 10094, Fig. 17) the 
difference between surface and bottom was only about 3° (48°-44.9°).
