... waters so far ranges from −69.6‰ (East Antarctic snow) to 29.2‰ (Sistan Desert, Iran) and, thus, covers a total range of approximately 100‰ ( Surma et al. 2015 ; Touzeau et al. 2016 ). In order to account for inter-laboratory scaling differences, a two-point calibration based on certified reference...

... rapidly melt. In contrast, annual melting of surface ice and snow deposits during late-season discharge events contribute to transport of water, but flux rarely surpasses the infiltration capacity of the active layer. These small discharge events do not erode channels of significant width. Even when...

...Abstract Abstract Snow albedo is an important climate parameter as it governs the amount of solar energy absorbed by the snow and can be considered a major contributor to the surface radiation budget. The present study deals with the estimation of temporal variation of snow albedo at the upper...

... the approximation T C ≈ T L is fairly precise for most caves. Effects of snow Moving northwards, the effect of a continental climate on the precipitation season holds, but an important new phenomenon is seen and is discussed here for the case of Perm (Russia). The average temperature in Perm is +1.7°C...

... for the reduction of lacustrine-alga population since the end of the Little Ice Age. We assume that the decrease in the Oron bioproductivity was mainly due to a deficit of nutrients caused by the inflow of ultrafresh waters from the thawing glaciers, snow patches, and seasonal snow cover of the Kodar Ridge during...

... m in altitude. The avalanche slopes have a flat surface at the top, with no trees, allowing the wind to transfer the snow and quickly overload the tops of the slopes, thus fostering an avalanche regime patterned on the storms. In the Québec City and Lévis regions, avalanches, much more frequent...
