    • 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 ...

    • Seasonal Changes in Dissolved Organic Matter Composition in a Patagonian Fjord Affected by Glacier Melt Inputs 

      Marshall, Matthew G.; Kellerman, Anne M.; Wadham, Jemma Louise; Hawkings, Jon R.; Daneri, Giovanni; Torres, Rodrigo; Pryer, Helena V.; Beaton, Alexander; Ng, Hong Chin; Urra, Alejandra; Robinson, Laura F.; Spencer, Robert G.M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-09)
      Biogeochemical processes in fjords are likely affected by changes in surrounding glacier cover but very little is known about how meltwater directly influences dissolved organic matter (DOM) in fjords. Moreover, the data available are restricted to a handful of northern hemisphere sites. Here we analyze seasonal and spatial variation in dissolved organic carbon (DOC) concentration and DOM composition ...
