• A predictive model for the spectral "bioalbedo" of snow 

      Cook, J.M.; Hodson, Andrew J.; Taggart, A.J.; Mernild, Sebastian H.; Tranter, M. (Journal article; Peer reviewed, 2017)
      We present the first physical model for the spectral “bioalbedo” of snow, which predicts the spectral reflectance of snowpacks contaminated with variable concentrations of red snow algae with varying diameters and pigment ...
    • Seasonal Dynamics of Methane and Carbon Dioxide Evasion From an Open System Pingo: Lagoon Pingo, Svalbard 

      Hodson, Andrew J.; Nowak, Aga; Redeker, KR; Holmlund, Erik S.; Christiansen, Hanne H; Turchyn, Alexandra V. (Journal article; Peer reviewed, 2019)
      The processes associated with the release of CH4 and CO2 from sub-permafrost groundwaters are considered through a year-long monitoring investigation at a terrestrial seepage site in West Spitsbergen. The site is an open ...
    • Spatial and temporal dynamics of dissolved organic carbon, chlorophyll, nutrients, and trace metals in maritime Antarctic snow and snowmelt 

      Nowak, Aga; Hodson, Andrew J.; Turchyn, Alexandra V. (Journal article; Peer reviewed, 2018)
      Despite scientific interest in the investigation of biogeochemical changes in meltwaters of the Antarctic Peninsula, we still lack an understanding of the seasonal dynamics and release of dissolved and particulate carbon, ...
    • Spatial Variability of Antarctic Surface Snow Bacterial Communities 

      Malard, Lucie A.; Sabacka, Marie; Magiopoulos, Iordanis; Mowlem, Matt C.; Hodson, Andrew J.; Tranter, Martyn; Siegert, Martin J.; Pearce, David A. (Journal article; Peer reviewed, 2019)
      It was once a long-held view that the Antarctic was a pristine environment with low biomass, low biodiversity and low rates of microbial activity. However, as the intensity of scientific investigation has increased, so ...
