Spatially consistent microbial biomass and future cellular carbon release from melting Northern Hemisphere glacier surfaces
peer reviewed AbstractMelting glacier ice surfaces host active microbial communities that enhance glacial melt, contribute to biogeochemical cycling, and nourish downstream ecosystems; but these communities remain poorly characterised. Over the coming decades, the forecast ‘peak melt’ of Earth’s gla...
