    • Arctic marine microbial ecology during the Svalbard Polar Night 

      Amargant Arumí, Martí (Master thesis; Mastergradsoppgave, 2018-05-15)
      This study investigated the presence and activity of the components of the microbial food web (sepcifically viruses, heterotrophic bacteria and nanoflagellates, and autotrophic Cyanobacteria and pico-nanoflagellates) in the waters around the Svalbard archipelago (Norway) during the polar night period. The study focused on two major questions – are there differences in the community composition in ...

    • Earlier sea-ice melt extends the oligotrophic summer period in the Barents Sea with low algal biomass and associated low vertical flux

      The decrease in Arctic sea-ice extent and thickness as a result of global warming will impact the timing, duration, magnitude and composition of phytoplankton production with cascading effects on Arctic marine food-webs and biogeochemical cycles. Here, we elucidate the environmental drivers shaping the composition, abundance, biomass, trophic state and vertical flux of protists (unicellular eukaryotes), ...
