Spatially consistent microbial biomass and future cellular carbon release from melting Northern Hemisphere glacier surfaces
Stevens, Ian T.; Irvine-Fynn, Tristram D. L.; Edwards, Arwyn; Mitchell, Andrew C.; Cook, Joseph M.; Porter, Philip R.; Holt, Tom O.; Huss, Matthias; Fettweis, Xavier; Moorman, Brian J.; Sattler, Birgit; Hodson, Andy J. (2022-11-10)Melting 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 ... -
Time‐lapse photogrammetry reveals hydrological controls of fine‐scale High‐Arctic glacier surface roughness evolution
Irvine‐Fynn, Tristram D. L.; Holt, Tom O.; James, Timothy D.; Smith, Mark W.; Rutter, Nick; Porter, Philip R.; Hodson, Andrew J. (2022-02-23)In a warming Arctic, as glacier snowlines rise, short‐ to medium‐term increases in seasonal bare‐ice extent are forecast for the next few decades. These changes will enhance the importance of turbulent energy fluxes for ...
