Scales of spatial heterogeneity for perennial and seasonal snow layers
Annals of Glaciology
Local observations of snow layers are used as the basis for spatial extrapolation of snow properties and for establishing a time record of snow deposition, yet significant lateral variations in layer thickness, density and microstructure are well documented. Here we examine the nature of layer heterogeneity over distances of 10– 100 000 m using data from primarily flat locations in Alaska, Antarctica and Greenland. We find that at a scale of 10 m or less, perennial snow layers on glaciers anddoi:10.3189/172756404781815112 fatcat:w6zefh56ffc7nolgr2c33czukq
