COLOR OF THE SEA. 
The observations on color, tabulated below, are interesting chiefly ie. 
because there is very little precise information as to the color of the 
water over the continental shelf south of Cape Cod. 
Color, in % of yellow, according to the Forel scale (Steuer, 1910).

The water was very green (27% yellow) along Cape Cod both in 
July and in August, and this was also the case on the western side of 
George’s Bank (20%). But it was distinctly bluer (9% yellow) over 
the southern end of the basin of the Gulf and after crossing Nantucket 
Shoals the water grew visibly blue to the eye, being almost pure blue 
(2% yellow) at the 80 fathom curve south of Nantucket (Station 
10061). 
In general the water was greenest near land, bluest off shore, as 
might be expected, the water being greenest of all near New York 
(Stations 10067, 10068). The color was 20-27% yellow along the 
coast of New Jersey; that of the coast water south of Delaware Bay 
14-20% yellow. The water was nearly pure blue (2% yellow) at all 
the stations outside the edge of the continental shelf. 
The water of the Gulf of Maine was considerably greener, most 50 
along Cape Cod (27% yellow), over German Bank (27% yellow), and 
along the coast of Maine between Mt. Desert and Penobscot Bay 
(27-35% yellow). The water was considerably bluer (9%) over the
