Characteristics of Water and Variations of Salinity, Temperature, and Dissolved Oxygen Content of the Water at Ocean Weather Station "P" in the Northeast Pacific Ocean

Vertical distributions of salinity, temperature, and dissolved oxygen content of the water at Ocean Weather Station "P" (lat. 50°N, long. 145°W) in the northeast Pacific Ocean have been examined for water characteristics, and deviations about their mean values. They are based on surveys made every alternate 6-week period during the 2 years between August 1956 and July 1958, and include data above the depth of 1500 metres. Temperature and salinity data are presented in two-dimensional frequency distribution on a temperature–salinity diagram. Variations at each depth during the 6-week periods are expressed in terms of standard deviations and ranges. Causes of these variations, when ascertainable, are discussed briefly.
