Melt water lake on 79°N Glacier in Greenland

by Ole Zeising, Alfred-Wegener-Institut, Bremerhaven, Germany

Melt water lakes are an impressive and beautiful consequence of warm summer temperatures on Greenlands glaciers. This photo of such a lake with clear blue water was taken from a helicopter on the 79°N Glacier in northeast Greenland during an expedition in July 2018. Supraglacial melt water runs along the surface slope into depressions where the water is accumulating until it refreezes or drains.
