    • 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, Andrew (Peer reviewed; Journal article, 2022)
      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 ...

    • Temporal Variability of Surface Reflectance Supersedes Spatial Resolution in Defining Greenland’s Bare-Ice Albedo 

      Irvine-Fynn, Tristram D. L.; Bunting, Peter S.; Cook, Joseph M.; Hubbard, Alun; Barrand, Nicholas E.; Hanna, Edward; Hardy, Andy J.; Hodson, Andrew J.; Holt, Tom O.; Huss, Matthias; McQuaid, James B.; Nilsson, Johan; Naegeli, Kathrin; Roberts, Osian; Ryan, Jonathan C.; Tedstone, Andrew J.; Tranter, Martyn; Williamson, Christopher J. (Peer reviewed; Journal article, 2022)
      Ice surface albedo is a primary modulator of melt and runoff, yet our understanding of how reflectance varies over time across the Greenland Ice Sheet remains poor. This is due to a disconnect between point or transect ...

    • 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 (Peer reviewed; Journal article, 2022)
      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 ...
