An ice-core record of net snow accumulation and seasonal snow chemistry at Mount Waddington, southwest British Columbia, Canada
A 141m-deep ice-core was retrieved from Combatant Col (51.39° N, 125.22° W, 3000m), Mount Waddington, Coast Mountains, British Columbia, Canada. Records of black carbon, dust, lead, and water stable-isotopes show that unambiguous seasonality is preserved throughout the core, despite summer surface snowmelt and temperate ice. High accumulation rates at the site (in excess of 5 m a) limit modific...
متن کاملIce-core net snow accumulation and seasonal snow chemistry at a temperate-glacier site: Mount Waddington, southwest British Columbia, Canada
A 141m ice core was recovered from Combatant Col (51.3858N, 125.2588W; 3000ma.s.l.), Mount Waddington, Coast Mountains, British Columbia, Canada. Records of black carbon, dust, lead and water stable isotopes demonstrate that unambiguous seasonality is preserved throughout the core, despite summer surface snowmelt and temperate ice. High accumulation rates at the site (>4m ice eq. a) limit modif...
متن کاملSeasonal variations of snow depth on Mars.
Using topography collected over one martian year from the Mars Orbiter Laser Altimeter on the Mars Global Surveyor (MGS) spacecraft, we have measured temporal changes in the elevation of the martian surface that correlate with the seasonal cycle of carbon dioxide exchange between the surface and atmosphere. The greatest elevation change (1.5 to 2 meters) occurs at high latitudes ( above 80 degr...
متن کاملYukon River streamflow response to seasonal snow cover changes
We used remotely sensed weekly snow water equivalent (SWE) and snow cover extent (SCE) data to investigate streamflow response to seasonal snowcover change over the Yukon watershed. We quantified the seasonal cycles and variations of snowcover (both SWE and SCE) and river streamflow, and identified a clear correspondence of river discharge to seasonal snowcover change. We also examined and comp...
متن کاملSpatial and temporal variability in seasonal snow density
Snow density is a fundamental physical property of snowpacks used in many aspects of snow research. As an integral component in the remote sensing of snow water equivalent and parameterisation of snow models, snow density may be used to describe many important features of snowpack behaviour. The present study draws on a significant dataset of snow density and climate observations from the Unite...
