Figure 4: Algal biomass and albedo.
From: The biogeography of red snow microbiomes and their role in melting arctic glaciers

Plot shows a significant negative correlation (Pearson correlation factor: r=−0.65, P=0.008) between algal biomass and surface albedo measured in red snow sites in Svalbard and Northern Sweden. This underpins the role of red pigmented snow algae in decreasing surface albedo and in turn melting.
