Icescape-scale metabolomics reveals cyanobacterial and topographic control of the core metabolism of the cryoconite ecosystem of an Arctic ice cap
Gokul, Jarishma K.; Mur, Luis A. J.; Hodson, Andrew; Irvine-Fynn, Tristram D. L.; Debbonaire, Aliyah R.; Takeuchi, Nozomu; Edwards, Arwyn (Peer reviewed; Journal article, 2023)Glaciers host ecosystems comprised of biodiverse and active microbiota. Among glacial ecosystems, less is known about the ecology of ice caps since most studies focus on valley glaciers or ice sheet margins. Previously we ... -
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 ...
