BIGELOW: COAST WATER EXPLORATION OF 1913. 



225 



deep basins; but nowhere in the Gulf did we find the beautiful ultra- 

 marine water which washes the continental slope. 



South of Cape Cod the general rule is that the water is bluest where 

 saltest, greenest where freshest; though this does not exactly cover 

 the case, because the water was bluer close off Chesapeake Bay than 

 off New York, although the salinity was lower. But in the Gulf of 

 Maine this rule did not hold either in 1912 (1914a) or in 1913, the 

 greenest water being intermediate in salinity, while the saltest water 

 was not the bluest. 



Current measurements. 



Measurements of surface and bottom currents with the Ekman 

 Current meter (Ekman, 1905b) were taken at three stations between 

 Cape Cod and Chesapeake Bay, with hourly readings for six hours at 

 each station. The directions are the compass bearings (magnetic) 

 toward which the current flows. Velocity in knots per hour is to the 

 nearest tenth of a knot. 



I. Station 10065, July 12. 

 High water at Fire Island Inlet at 2.05 p.m.
