Supraglacial debris thickness variability: impact on ablation and relation to terrain properties

Lindsey I. Nicholson, Michael McCarthy, Hamish D. Pritchard, and Ian Willis

Data sets

Supraglacial debris thickness data from Ngozumpa Glacier, Nepal L. Nicholson and M. McCarthy

Short summary
Ground-penetrating radar of supraglacial debris thickness is used to study local thickness variability. Freshly emergent debris cover appears to have higher skewness and kurtosis than more mature debris covers. Accounting for debris thickness variability in ablation models can result in markedly different ice ablation than is calculated using the mean debris thickness. Slope stability modelling reveals likely locations for locally thin debris with high ablation.
