Scattered Icebergs on a proglacial Lake
The image shows icebergs that recently have been released by calving from the floating glacier terminus of Tasman Glacier in the Southern Alps/New Zealand. In this unusual perspective from high above the grey lake water with a high suspended sediment load (silt) contrasts with the colour of icebergs. The latter are mostly still covered by supraglacial debris or show englacial debris bands. They reflect that the lower glacier tongue of Tasman Glacier, currently retreating by calving into its rapidly expanding proglacial lake, is completely debris-covered.
