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 
oft 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.
