متن کاملNear-surface permeability in a supraglacial drainage basin on the Llewellyn Glacier, Juneau Icefield, British Columbia
Supraglacial channel networks link time varying melt production and meltwater routing on temperate glaciers. Such channel networks often include components of both surface transport in streams and subsurface porous flow through near-surface ice, firn or snowpack. Although subsurface transport if present will likely control network transport efficacy, it is the most poorly characterized componen...
متن کاملGlacier changes in southeast Alaska and northwest British Columbia and contribution to sea level rise
[1] The digital elevation model (DEM) from the 2000 Shuttle Radar Topography Mission (SRTM) was differenced from a composite DEM based on air photos dating from 1948 to 1987 to determine glacier volume changes in southeast Alaska and adjoining Canada. SRTM accuracy was assessed at ±5 m through comparison with airborne laser altimetry and control locations measured with GPS. Glacier surface elev...
متن کاملStratigraphic evidence for multiple Holocene advances of Lillooet Glacier, southern Coast Mountains, British Columbia
Holocene lateral moraines in the Coast Mountains of British Columbia are commonly composed of multiple drift units related to several glacier advances. In this paper, we document lateral moraine stratigraphy at Lillooet Glacier in the southern Coast Mountains. Five tills, separated by laterally extensive paleosols and layers of large woody debris, were found in three cross-sectional exposures t...
متن کاملDiatreme Breccias in British Columbia*
INTRODUCTION Over the last decade considerable interest has been expressed in diarreme breccias ofpc~ssible kimberlitic affinity in British Columbia (Fipke, 1983; Fipk.: and Capell, 1983; Grieve, 1981 and 1982; Roberts, et a/., 1980; Woodcock, 1978; etc.). This interest has been heightened by the reported recent discovery of diamonds in pipes north of Golden (Durnmet, rr a / . . 1985; Northcote...
