Blooms of pigmented microalgae accelerate glacier and ice sheet melting by reducing the surface albedo. Here, Halbach et al. use single-cell measurements of elemental composition and nutrient assimilation rates of glacier ice algae, showing that the algae are well adapted to the ice’s oligotrophic conditions and exhibit no significant changes in productivity in response to nutrient additions.
