The more detailed physical and chemical data 
presented in this paper for the Queen Charlotte 
Strait area were obtained during two cruises, 
one (53/1) on the C.G.M.V. "Cancolim II” in 
1953 (anon., 1955^) and the other (56/1) 
on the CN.A.V. "Ehkoli” in 1956 (anon., 
1956^). The stations occupied during these two 
cruises are indicated in Figures 5 and 6, respec- 
tively. Further less detailed observations were 
made on a cruise (57/6) in May, 1957, on the 
CN.A.V. "Clifton” (anon., 1958). In analyzing 
the seasonal characteristics and annual fluctua- 
tions of temperature and salinity that occur, 
reference has been made to the data obtained 
in the area from the daily records (anon., 1944, 
1946, 1948 b, 1949, 1950, 1951, 1952 b, 1953 a, 
1955c, 1956c) and data reports of the Hecate 
Strait Project (anon., 1955 b, 1955 d, 1955c, 
195 6b) of the Pacific Oceanographic Group. 
Meteorological data have been obtained from 
the Meteorological Observations in Canada 
(anon., 1953 b), and tidal data were taken from 
the Pacific Coast Tide Tables (anon., 1952*). 
Chart data have been taken from charts of the 
Canadian Hydrographic Office and the British 
Admiralty. Some additional physical and chem-
