Chapter VI 



THE AMERICAN SECTOR 



The American sector is the term applied here to the shelf and slope 

 waters embraced by the U. S. Coast Guard's surveys north of St, 

 John's, Newfoundland, during the years 1928, 1931, "1933, and 1934. 

 The 1928 observations, upon which the discussion is based, were made 

 along a series of sections, H to Q, as shown on figure 46. 



Figure 46 — The American sector, 1928. Sections are as follows : H, Cumberland Sound ; 

 I, Frobisher Bay ; J, Resolution Island ; K, Naehvak Fjord ; L, Cape Harrigan ; M, 

 Hamilton Inlet ; N, Domino Island ; O, Belle Isle ; P, White Bay ; and Q, St. John's. 



The American sector embraces two principal slope currents — the 

 Baffin Land Current and the Labrador Current. This division of the 

 south flowing waters along the American continental slope, from El- 

 lesmere Land to the Grand Banks, into two currents, differs mate- 

 rially from the j)revious classifications. As a rule, the flow over this 

 entire range is considered as pertaining to one current, the Labrador.
