    • Biogeochemical processes in the active layer and permafrost of a High Arctic fjord valley 

      Jones, Eleanor; Hodson, Andrew; Thornton, Steven F.; Redeker, Kelly Robert; Rogers, Jade; Wynn, Peter M.; Dixon, Timothy J.; Bottrell, Simon H.; O’Neill, H. Brendan (Journal article; Peer reviewed, 2020)
      Warming of ground is causing microbial decomposition of previously frozen sedimentary organic carbon in Arctic permafrost. However, the heterogeneity of the permafrost landscape and its hydrological processes result in ...

    • Biogeochemistry of low- and high-centered ice-wedge polygons in wetlands in Svalbard 

      Jones, Eleanor L.; Hodson, Andrew; Redeker, Kelly Robert; Christiansen, Hanne H.; Thornton, Steve F.; Rogers, Jade (Peer reviewed; Journal article, 2023)
      Arctic wetlands are a globally significant store of soil organic carbon. They are often characterized by ice-wedge polygons, which are diagnostic of lowland permafrost, and which greatly influence wetland hydrology and ...

    • Marked Seasonal Changes in the Microbial Production, Community Composition, and Biogeochemistry of Glacial Snowpack Ecosystems in the Maritime Antarctic 

      Hodson, A.J.; Šabacká, Marie; Dayal, A.; Edwards, Arwyn; Cook, J.; Convey, Peter; Redeker, Kelly Robert; Pearce, D.A. (Peer reviewed; Journal article, 2021)
      We describe seasonal changes in the biogeochemistry, microbial community and ecosystem production of two glacial snowpacks in the maritime Antarctic during a cold summer. Frequent snowfall and low, intermittent melt on the ...

    • Sub-permafrost methane seepage from open-system pingos in Svalbard 

      Hodson, Andrew; Nowak, Aga; Hornum, Mikkel Toft; Senger, Kim; Redeker, Kelly Robert; Christiansen, Hanne H; Jessen, Søren; Betlem, Peter; Thornton, Steve F.; Turchyn, Alexandra V.; Olaussen, Snorre; Marca, Alina (Journal article; Peer reviewed, 2020)
      Methane release from beneath lowland permafrost represents an important uncertainty in the Arctic greenhouse gas budget. Our current knowledge is arguably best developed in settings where permafrost is being inundated by ...
