    • Benthic dissolved silicon and iron cycling at glaciated Patagonian fjord heads 

      Ng, Hong Chin; Hawkings, Jon R.; Bertrand, Sebastien; Summers, Brent A.; Sieber, Matthias; Conway, Tim M.; Freitas, Felipe S.; Ward, James P.J.; Pryer, Helena V.; Wadham, Jemma Louise; Arndt, Sandra; Hendry, Katharine R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-18)
      Glacier meltwater supplies silicon (Si) and iron (Fe) sourced from weathered bedrock to downstream ecosystems. However,the extent to which these nutrients reach the ocean is regulated by the nature of the benthic cycling of dissolved Siand Fewithin fjord systems,given the rapid deposition of reactive particulate fractions at fjord heads. Here, we examine the benthic cycling of the two nutrients at ...

    • Biogeochemical consequences of a changing Arctic shelf seafloor ecosystem 

      März, Christian; Freitas, Felipe; Faust, Johan Christoph; Godbold, Jasmin A.; Tessin, Alyson; Abbott, Geoffrey D.; Airs, Ruth; Arndt, Sandra; Barnes, David K.A.; Grange, Laura; Gray, Neil; Head, Ian M.; Hendry, Katharine R; Hilton, Robert; Reed, Adam J.; Ruhl, Saskia; Solan, Martin; Stevenson, Mark A; Tait, Karen; Ward, James M.; Widdicombe, Stephen; Souster, Terri A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-09)
      Unprecedented and dramatic transformations are occurring in the Arctic in response to climate change, but academic, public, and political discourse has disproportionately focussed on the most visible and direct aspects of change, including sea ice melt, permafrost thaw, the fate of charismatic megafauna, and the expansion of fisheries. Such narratives disregard the importance of less visible and ...
