Direct monitoring of stream water chemistry is an increasingly important tool for securing stream water quality and assessing stream ecological functioning as it relates to overall ecosystem health. S...
Within an area of about 5 km2, 25 wells were drilled to depths of about 90 m for groundwater observation. The wells were sampled and analyzed, and from the results it could be concluded that the ion...
Chemical changes in water circulating deep in the fissures of the solid rock are studied. The ultimate chemical composition is determined by the conditions of percolation through the soil zone. For ...
Within three areas in Southeastern Norway, Lake Mjosa district, As and Moss - Jeloy, groundwater samples for chemical analysis were collected during the years 1971-77 from 98 drilled wells in bedroc...
High precipitation amounts of strongly varying ionic composition make the western parts of southern Norway well-suited for studies of certain relationships between precipitation chemistry, hydrology...
600 mm of artificial, "unpolluted" precipitation with a chemical composition of assumed preindustrial quality ((HC] = 9 peql-I. ISO,] = 11 peql-') was sprayed on a "mini-catchment" (98 m2) over a pe...
The pH, 613c of total dissolved carbon and HCO;, Ca2*, Ca2+ + Mg2+ contents in spring waters were investigated. Changes of these values were recorded for 8 months of 1982 and 1983. The changes were ...
Two subarctic fens (one nutrient-poor, one nutrient-rich) were sampled from October, 1984 to July, 1985 near Schefferville, northern Quebec. The changes in concentations of chemicals (pH, conductanc...
Depth profiles of chemical impurities found in snow and ice have usually been interpreted simply in terms of temporal changes in atmospheric concentrations of the species of interest. Measurements o...
Catchment areas of Icelandic rivers are mostly barren or with little vegetation cover in the highlands, but with heathland and mire vegetation in the lowlands. Chemical composition and nutrient avai...
Chemical profiles in snowpacks were observed during snow accumulation and melt periods at subalpine sites in the southern interior of British Columbia. During accumulation periods, concentrations of...
The geocheinical model MAGIC (5.01) was applied to the Berg - Pipbacken Nedre catchment in southwestern Sweden for the period 1846-2020. The major objective was to reconstruct historical acidificati...
Water chemistry and bacterioplankton were analysed for two subalpine rivers, River Kidisjoki and River Utsjoki, in northernmost Finland. The data set is based on continuous runoff measurements and w...
Twenty groundwater samples were collected and analyzed from several hand-dug wells at El-Tur City, South Sinai, Egypt. The results of chemical analyses indicate that the water types are Na2SO4 of mete...
Rain, throughfall, soil waters from surface peaty O horizon and deeper mineral B horizon, and stream water, were collected every four weeks for one year in a moorland catchment, and in four forested c...
