Description
Summary:Ionic concentration of snow prior to meltoff in 1990 as in previous years ranged widely from point to point within the basin. Overland flow began on May 12 and was monitored at closely-spaced time intervals for discharge volume and ionic concentrations to better define this relationship in non-channelized flow. Ionic concentration in both watertrack flow and in Imnavait Creek were closely monitored during meltoff. During the post melt period daily sampling was maintained in watertrack 7 and Imnavait Creek. Rainfall collection and analysis on an eight day schedule was maintained as in previous years. Soil solution composition was monitored on an event basis in conjunction with a similar schedule of precipitation sampling to determine relationships between precipitation and near surface and overland flow. Composition of deeper soil solution was also monitored and sampled for {sup 18}O analyses to determine the age structure of water contributed by the active layer to stream and watertracks. A pilot experiment employing salt tracers was conducted across landscape units to determine rates and pathways of soil solution movement in response to individual rain events. Nutrient addition in rime and fog were also recorded to add detail to the input side of the balance equation.
