    • Seasonal riverine inputs may affect diet and mercury bioaccumulation in Arctic coastal zooplankton 

      Carrasco, Nathalie; Mcgovern, Maeve; Evenset, Anita; Søreide, Janne E.; Arts, Michael T.; Jonsson, Sofi; Poste, Amanda Elizabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-06)
      Climate change driven increases in permafrost thaw and terrestrial runoff are expected to facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas in the Arctic, potentially increasing Hg exposure of marine food webs. The main aim of this study was to determine the impacts of seasonal riverine inputs on land-ocean Hg transport, zooplankton diet and Hg bioaccumulation ...

    • Seasonality in mercury bioaccumulation in particulate organic matter and zooplankton in a river-influenced Arctic fjord (Adventfjord, Svalbard). 

      Carrasco, Nathalie (Master thesis; Mastergradsoppgave, 2019-05-15)
      Methylmercury (MeHg) is of concern because it has the capacity to readily bioaccumulate and biomagnify along trophic levels until humans, exhibiting toxic effects such as neurotoxicity. Increased permafrost melt (that stores large amounts of carbon and mercury (Hg)) and river inputs, are expected to increase the exposure to Hg through uptake and transfer of contaminants through the food web. The ...
