On March 25 and 26, 1919, Mayor (1922) found the alkalinity to be as follows

Henderson and Cohn (1916) found the alkalinity of several Gulf of Maine sam- 
ples to vary from pH 8.031 to pH 8.102. 
Off the Atlantic coast of the United States, between New York and the Tortu- 
gas, Mayor (1922) has reported a range of pH from 7.95 to 8.23, noting a character- 
istic difference between the gray-green coastal water, with a pH of about 8, and 
the deep blue gulf stream outside the edge of the continent, with a pH upward of 8.2. 
The pH as tabulated above shows the Gulf of Maine to fall among the less 
J! For general summaries of the measurements of pH that have been made in various seas, see Clark (1920), Atkins (1922), 
and Palitzsch (1923).
