BIGELOW: COAST WATER EXPLORATION OF 1913.

band of water of the same low salinity extending thence along the coast 

 of Maine to the Grand Manan Channel. The salinity was 32.5%o or 

 less over the coast bank west of Nova Scotia ; and it is probable that 

 the surface of the Bay of Fundy was even fresher than this. The 

 curve for 34.4%o shows that the direct effect of Penobscot water did 

 not extend further south than Jeffrey's Bank (Station 10091), south 

 of which it runs in an S, roughly parallel with the coast, crossing the 

 southern end of the basin, and thence westward across Nantucket

Shoals. The surface of the eastern half of the Gulf as a whole was 

 Salter than 32.6%o; the curve for that value outlining a tongue some 

 sixty miles broad, with an eddy-like curve from southeast to north- 

 west. Water as salt as this lay close to the land east of Mt. Desert 

 Island, and indented westward, as far as Matinicus Island, into the 

 fresher Penobscot water. The curve of 32.6%o probably crossed the 

 mouth of the Bay of Fundy. At any rate it paralleled the western 

 shore of Nova Scotia, where it was separated from the land by fresher 

 water (32.45%o on Lurcher Shoal).
