Description

Debris thickness measurements collected from seven debris-covered glaciers in Switzerland and Italy in 2019 and 2020. Only data from Miage Glacier was measured in September 2020 all others were measured in August and September in 2019. The RGI Glacier ID is the first cell in each sheet. Location data is reported in decimal degrees. All debris thickness data is in centimeters and elevation data is in meters.

Debris was measured by digging through the debris and then directly measuring the debris thickness with a measuring stick. The mean thickness is the most likely average thickness based on 3 measurements within a ~4x4m area. The 'min' measurement is the minimum debris thickness. The 'max' measurement is the absolute maximum estimate of the mean debris thickness, meaning that this estimate is that absolute maximum of the mean debris thickness. This value is determined based on the thickness of the largest non-outlier debris thickness in the area. Three measurements were taken for the mean value and 1 each for the max/min bounds. To save time, sites with mean thicknesses larger than 20 cm the extreme bounds are based on the minimum and maximum measurements within the single hole dug.  Elevation data are based on a hand held GPS and this value was only recorded for some debris thickness measurements.
