"Liane G. Benning has won the grant with the project "DEEP PURPLE". Together with colleagues, she is investigating the relationship between geology, geochemistry, biology and climate on the basis of the increasing algal bloom on Arctic snow and ice surfaces. On Greenland, the teams from Aarhus, Bristol and Potsdam are investigating how glacial algae grow and interact with their icy habitat. The pink to purple microorganisms darken the surface of the ice sheets and thus accelerate the melting of the glaciers."

This is increasingly a problem in the Arctic, Alpine and Himalayan glaciers. Blooms of red snow and brown ice are turning up in Antarctica also." - The British newspaper @guardian featuring the @GFZ team including @LianeGBenning in an interesting piece on how algae increase the darkening and melting of the Greenland Ice Sheet: https://theguardian.com/environment/2019/sep/18/tiny-algae-ground-zero-greenland-melting-glaciers.
