Fig. 3: Cell concentration and size distributions within the weathering crust and supraglacial streams at each investigated glacier.

All distributions are box and whisker plots displaying median, 25 to 75 percentiles, distribution range and outlying sample measurements (as grey dots) for each glacier in latitudinal order (from north to south). Each site is coded by RGI region (ACN: Arctic Canada North; Sca.: Scandinavia; GP: Greenland Periphery and GIS: Greenland Ice Sheet; and glacier identifier (listed in Fig. 2). Sample numbers (n) correspond to the abundance box plots with which they vertically align.
