Regional surveys of the chemistry of the snowpack in Norway, late winter 1973, 1974, 1975 and 1976

In late winter 1973, 1974, 1975 and 1976 samples of the snowpack were collected from 23 to 165 sites in Norway (and adjacent areas of Sweden and Finland in 1976) and the concentrations of major ions and several trace metals determined. In southeastern and northernmost Norway the snowpack was characterized by high concentrations of H +, SO 4, NO 3, and NH 4, components that come principally from the long-range transport of air pollutants. Along the west and northwest coast the snowpack was dominated by the seawater salts, Cl, Na, and Mg. The patterns of concentration of these two groups of components in the snowpack were similar to those in fresh precipitation collected at 16 stations in Norway. The concentrations in the snowpack, however, were generally less than those measured in winter precipitation, probably due to mid-winter melting that preferentially depletes the snowpack in chemical impurities. Snowpack and precipitation chemistry in Norway apparently results from the admixture of continental long-range transported air pollutants with marine aerosols. Deposition is enhanced by orographie effects.

Correlations between cone resistance and vane shear strength in some Scandinavian soft to medium stiff clays

Vane shear strength and cone resistance for Scandinavian soft to medium stiff clay has been compared for six different sites in Norway and Sweden.At five of the sites, three in Drammen, one in Onsøy, and one in Gøteborg, the clays have been sedimented in an entirely marin environment. At the Skå-Edeby site the conditions have been marine-brackish or brackish-marine.When compared with the standard field vane shear strength, the cone factor, Nk (in the formula: qc = Nk∙[Formula: see text]f + γ∙z), varies between 13 and 24 for the five marine clays. For the Skå-Edeby clay the Nk values lie in the range 8 to 12.Corrections of field vane shear strength result, for the five marine clays, in Nk values between 15 and 19 with an average of 17. This Nk value can be used for Scandinavian marine normally consolidated clays, but may not be valid in other types of clays. An example of this is the Skå-Edeby brackish-marine clay where the corrected Nk values fall between 11 and 13.

Distribution and estimation of standing crop of zooplankton in a mountain lake with fast renewal

Zooplankton distribution has been studied in lake Ovre Heimdalsvann, an IBP/PF site in Norway, for the purpose of obtaining reasonably good estimates of standing crop for zooplankton measurements. ...
