TY - Generic T1 - A portable profiling snow gauge - results of field tests on glaciers T2 - 44th Annual Western Snow Conference Y1 - 1976 A1 - Young, G.J. KW - Glacier coring, Glacier research studies, Radioactive snow gauges, Snow gauges AB - During the past two years a 'Digiray' portable profiling snow gauge used in conjunction with a Mt. Rose sampler has been tested for accuracy, reliablity and convenience on glaciers in Western Canada. There have been several small mechanical failures, but the electronics have on the whole proven reliable. The instrument has to be back-packed and this can be done conveniently if three men are available. The most important single limitation to the effectiveness of the system lies not in the accuracy, reliability or convenience of the probe itself but in the difficulty of cutting through very compact snow and ice lenses at depths exceeding 6 m with a Mt. Rose sampler. Despite several reservations about the system it is still regarded as a practical alternative to digging deep snow pits.

KW - Snow cover - distribution of glaciers, Snow -measurement AB - A stratified sampling design for snow accumulation studies is described. The design is currently being used on five glaciers in Western Canada. The method can also be applied to non-glacierized basins.Difficulties of mapping snow cover distributon and of calculating areal totals of snowpack volume are discussed. Previous studies have shown that snow depths at point locations are associated with slope angle and local relief of the surface; it is argued that if depth samples are taken in areas of mean surface slope and mean local relief, then mean snow depth will be realistically defined. To this end, meaures of surface slope and local relief are generated at all grid line intersections of a square mesh (of interval 100m) covering the glacier. The glacier surface is then classified into areas which are typical in terms of these measures. Depth sampling is carried out within such 'typical' areas.A detailed discussion is given of how the method can be implemented for a study area.
