Difficulties in Deducing Temporal Changes in Precipitation Chemistry from Snow and Ice Cores:The Spatial Variability Problem
Temporal Changes Precipitation Chemistry Snow and Ice Cores Spatial Variability Problem
2009/10/26
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...
Assessment of Spatial Variability of Major-Ion Concentrations and DEL Oxygen-18 Values in Surface Snow,Upper Fremont Glacier,Wyoming,U.S.A.
Spatial Variability Major-Ion Concentrations DEL Oxygen-18 Values
2009/10/26
One hundred samples were collected from the surface of the Upper Fremont
Glacier at equally spaced intervals defined by an 8,100 m 2 snow grid to assess
the significance of lateral variability in ma...
Field Observations of Small Scale Spatial Variability of Snowmelt Drainage and Infiltration
Field Observations Small Scale Spatial Variability Snowmelt Drainage
2009/10/23
De-icing chemicals (containing 1,2 propane diol and potassium acetate) used on
airports in winter time mix with snow and start infiltrating along the runways in
spring. The distribution of the chemi...
Spatial Variability of Contaminant Transport in a Fractured Till,Avedøre Denmark
Spatial Variability Contaminant Transport Fractured Till
2009/10/23
A field experiment shows that rapid downward migration of solutes and microorganisms
can occur in a fractured till. A solute tracer, chloride, and a bacteriophage
tracer, PRD-1, were added to ground...
Spatial variability of nitrate concentration in lakes in Snowdonia, North Wales, UK
Spatial variability North Wales nitrate concentration
2009/5/26
At a regional scale, high nitrate (NO3‾) concentrations in upland surface waters generally occur in tandem with high nitrogen (N) deposition levels. However, significant differences in the patte...
