PHYSICAL OCEANOGRAPHY OP THE GULP OP MAINE

the form of a U or V, its concavity directed toward the southwest, its one arm 
roughly paralleling and somewhat overlapping the 100-meter contour off the Nova 
Scotia coast, its other arm similarly paralleling the coast of Maine westward as far 
as the offing of Penobscot Bay (figs. 135 and 136). In my account of the salini- 
ties of 1913 I assumed that this saltest tongue was continuous with the still higher 
salinities outside the continental shelf via the southeastern part of the gulf (Bige- 
low, 1915, pi. 2). However, continued investigation of the gulf has made it more 
likely that this was actually an isolated pool surrounded by less saline water on the 
south, as was certainly the case in July and August, 1914 (fig. 136). This was.
