BIGELOW: COAST WATER EXPLORATION OF 1913.

The density profile (Fig. 62) crossing the Gulf from Massachusetts 

 Eay (Station 10106) to German Bank (Station 10095) shows that the 

 water was nearly uniform horizontally, depth for depth, below seventy 

 fathoms. In the mid-depths the water was densest at Station 10092. 

 Over German Bank there is a distinct spreading of the curves reminis- 

 cent of, and due to the same cause, as the spreading of the tempera- 

 ture and the salinity curves in that region. And the same condition

prevails below twenty fathoms in Massachusetts Bay, just as described 

 for salinity (p. 208). 



A profile from Station 10102, near Penobscot Bay, across Jeffrey's 

 Bank to the centre of the Gulf (Fig. 63) shows a slight rise in density 

 passing off shore, the difference being greatest in the mid-depths. 

 But a parallel profile further east would be exactly the reverse, the 

 surface density being higher at Stations 10101, 10100, and 1009S than 

 at either Station 10092 or 10093.
