Abstract
During the arctic summer 1978 hydrochemical investigations were carried out in the area of Oobloyah Valley. Samples of precipitation, soils, lakes and rivers of different types (periglacial, glacial and mixed glacial/periglacial) were analysed. The following results can be presented: 1. All precipitations had similar chemical characteristics, except those of July 16, that show a significant high peak in sulphate with concentrations of 12 mg/l. .... 2. The chemistry of soil water is mainly affected by the subsoil relief of the permafrost-table. If the draining soil water cannot discharge, as this happens in the sediment of the frostboils, the concentration of soil water in the wet zone beneath the top of the frost boil increases. 3. The chemistry of the two examined lakes especially the calcium content is strongly related to the course of concentration of soil water at station II which was installed in moraine sediment. Precipitation causesdilution,.... 4. The three examined rivers show, according to their hydrological types, different chemical behaviour. Causal connections to other hydrometric parameters (discharge, air temperature, precipitation) could be found only for the periglacial Peri Creek. In this creek the soluted freight is increasing meanwhile the daily discharge decreases. The concentration of calcium in the glacial Nukapingwa River is dependent on the area of the river bed which is flooded during high water level. In the mixed glacial-periglacial Heidelberg River the amount of potassium and sodium is correlated to the transport of silt sediment in the river which is eroded in the upper parts of the river. Those ions were absorbed by this material and were exchanged during the time of storing the samples till they were analysed in the laboratory. 5. Only in the Peri Creek we found a correlation between the total diluted freight and the daily discharge. The linearregression between these two parameters is not very strong and therefore it is not useful to compute the diluted freight by the daily discharge.
