BIGELOW: COAST WATER EXPLORATION OF 1913.

At the one Station in Massachusetts Bay (Station 10106, Fig. 16) 

 the upper part of the temperature curve agreed almost exactly with 

 the water off Cape Ann, (Station 10087) and near Piatt's Bank (Sta- 

 tion 10089), cooling from 61° at the surface to 48.5° at fifteen fathoms. 

 But at thirty-five fathoms (bottom) it was 2° warmer (44.1°) than 

 either of these. 



All the temperatures described so far for the Gulf were taken in 

 August, during a week's period: and hence directly comparable

with one another. But three Stations, one off Cape Cod (Station 

 10057, Fig. 16) at the same location as Station 10086, one over the 

 southern part of the basin (Station 10058, Fig. 3), the third on George's 

 Bank (Station 10059, Fig. 3), were made a month earlier. The surface 

 temperature of the first (61°) is exactly the same as it was at the same 

 locality in August (Station 10086); but below the surface the July 

 section is colder at all depths, the greatest difference being on the
