BIGELOW: COAST WATER EXPLORATION OF 1913.

Evidently then, the immediate coast water from Cape Ehzabeth to 

 and across the mouth of Penobscot Bay was distinctly warmer than 

 the coast water further south, or than the water off shore, water 

 colder than 42° being limited, on the northeast by the slope of Jeffrey's 

 Bank. We have no means of knowing how far south water colder 

 than 42° may have extended in August. But the fact that in early

 the coast of Maine (Station 10098) to German Bank (Station 10095) cross- 

 ing the northern end of the basin (Station 10097). 



July it filled the basin off Cape Cod, from thirty fathoms to bottom, 

 suggests that it reached the northwestern side of Georges Bank, though 

 probabl}" underlaid by warmer water in the southern part of the basin, 

 just as at Station 10088. 



A profile from the basin toward the Bay of Fundy (Fig. 27) shows 

 that vertical tidal mixing was effective from German Bank to Lurcher 

 Shoal, diminishing toward the north, to reappear again off the coast of 

 Maine (Fig. 28).
