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

 and Palitzsch (1923).
