BIGELOW: COAST WATER EXPLORATION OF 1913. “Ol 
is reversed, 2. e., the water was saltest, depth for depth, next the land, 
suggesting a movement of bottom water up the slope. The general 
rule that the salinity of the upper layers rose steadily passing off shore 
was broken at Station 10097; but this was probably due to local verti- 
eal circulation, as evidenced by the vertical uniformity of salinity 
for the upper thirty fathoms. 
The profile crossing the mouth of the Bay of Fundy from the coast 
of Maine to German Bank (Stations 10098, 10097, 10096, and 10095, 
Fig. 53) shows the same comparatively fresh shore water off the coast 
of Maine, and the water was only slightly salter on German Bank, at 
the southern end of the profile. But the salinity was much higher in 
the centre of the profile, where ;
