The variation in the K+/Na+ and Ca++/Na+ ratios in highly diluted sea waters near the heads of two British Columbia inlets has been determined flame photometrically. Although the values agree in general with those calculated from the effect of dilution, discrepancies larger than the analytical error appear. These discrepancies may be explained by cation exchange processes taking place where the silt suspended in the river meets the sea.

Chemical data are presented for the concentrations of sodium, potassium, magnesium, calcium, strontium, chloride, bromide, sulphate, carbonate, boron, silicon, phosphorus, and nitrogen in some lakes and rivers of the Western District of Victoria. All these waters are of the chloride type and sodium is the dominant cation. Comparatively high pH values are common. Several ionic ratios have been calculated and these are used to illustrate relative enrichments or losses among the ions present during an overall increase in total salinity. Precipitation of dolomitic carbonate is indicated. The similarity of several ionic ratios to those of sea water is used to propose an oceanic origin for these inorganic constituents. Clay membrane mechanisms coupled with solar evaporation are suggested as an explanation for the extreme salinity range of samples.

Extractable Cations

The equilibration of acid soils, a Sombric Ferro-Humic Podzol (CSSC-2) from British Columbia, an Orthic Ferro-Humic Podzol (CSSC-19) from Quebec and two horizons of a Dystric Brunisol (SSD-330, SSD-331) from British Columbia, with CaSO4 solution demonstrated that SO4 ions reacted with components of these soils. These reactions increased soil pH, ion activity product (Al)(OH)3 and neutral salt extractable exchangeable cations. The increase in pH and ionic activity product (Al)(OH)3 were noticeable on a single equilibration; however, increase in neutral salt extractable cations was only observed after subsequent equilibrations. After three equilibrations, the sums of NaCl extractable cations were 6.56, 11.99, 5.62 and 4.31 meq/100 g for soil samples CSSC-2, CSSC-19, SSD-330 and SSD-331, respectively. The corresponding values for the unequilibrated soils were 5.20, 7.49, 4.30 and 2.50 meq/100 g. On further equilibration there was no increase in total extractable cations for sample CSSC-2; however, for the other three samples there were increases which became progressively smaller. The reaction of SO4 ions with aluminum hydroxy clay complexes seems to be the mechanism for the increase of negative sites. Key words: Cation exchange capacity, CaSO4, acid soils

Run Off

Grand monthly means of daily observations of surface sea-water temperature and salinity from twelve light stations along the British Columbia coast during the 13 years 1935 to 1948 have been analysed. In general the temperatures reach a minimum of 45°F. ± 1° (7.2 °C. ± 0.5°) in January and February. The maximum varies from 50° to 64°F. (10° to 18 °C.) in August. The warmest waters occur in bays protected from wind action, and the coldest waters occur in regions of turbulent mixing due to wind or strong currents. The salinity along the mainland coast is a minimum in early summer, associated with the maximum run-off from melting snow. Along the west coast of Vancouver Island the minimum occurs in mid-winter, associated with maximum precipitation which is not stored as snow in this region. At the southern and northern tip of the Queen Charlotte Islands there is little or no variation of salinity because there is no land drainage of consequence in the vicinity.In passes between Georgia Strait and the sea where the waters are mixed to homogeneity by strong tidal currents the annual variation of temperature and salinity is reduced, and in some cases entirely suppressed.On the west coast of Vancouver Island it is shown that the annual cycle is affected by the dominant winds and upwelling of deep ocean waters.
