SNOW-WATER EQUIVALENT MEASUREMENT USING NATURAL GAMMA EMISSION
SNOW-WATER EQUIVALENT MEASUREMENT NATURAL GAMMA EMISSION
2009/10/29
The natural gamma radiation emitted by potassium, uranium and thorium
is attcnuated by snow. This attenuation depends on the water-equivalent
of the snow layer. Air absorption coefficients were dete...
Chemical Budgets and Chemical Quality of Snow and Runoff During Spring Snowmelt
Chemical Budgets Chemical Quality Spring Snowmelt
2009/10/28
In connection with water acidification and the subsequent disappearance of
fish populations and also massive fish kills during spring floods, particular
interest has been focused upon the fate and e...
Meltwater Hydrology and Hydrochemistry in Snow- and Ice-Covered Mountain Catchments
Meltwater Hydrology Hydrochemistry Snow- and Ice-Covered Mountain Catchments
2009/10/28
Electrical conductivity, a surrogate measure of total dissolved solids content,
and discharge of meltwaters draining from two adjacent contrasting watersheds
in the Rocky Mountains, Canada, were rec...
Isotope Input into Runoff Systems from Melting Snow Covers
Isotope Input Runoff Systems Melting Snow Covers
2009/10/28
Stable environmental isotope techniques contribute to reasonable separations
of the direct runoff component in snowmelt hydrographs. For the separation
procedure, the actual isotope input from snow ...
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...
Relocation of Major Ions in Snow along the Tundra-Taiga Ecotone
Relocation of Major Ions Tundra-Taiga Ecotone
2009/10/26
The chemistry of seasonal snowcovers north of Inuvik, Northwest Territories,
Canada was stratified by biophysical landscape. In this region, deposition of
ions in winter occurs largely through the r...
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...
Release of Major Ions and Hydrogen Peroxide from Homogeneous,Melting Snow
Major Ions Hydrogen Peroxide Melting Snow
2009/10/26
We undertook two laboratory experiments to study the change of concentrations
and the preferential elution of major ions and hydrogen peroxide during melting
of a homogeneous snow pack. The elution ...
Snowpack Chemistry During Snow Accumulation and Melt in Mature Subalpine Forest and Regenerating Clear-Cut in the Southern Interior of B.C.
Snowpack Chemistry Snow Accumulation Mature Subalpine Forest
2009/10/23
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...
