      Yakushev, Evgeniy; Gebruk, Anna; Osadchiev, Alexander; Pakhomova, Svetlana; Lusher, Amy; Berezina, Anfisa; van Bavel, Bert; Vorozheikina, Elena; Chernykh, Denis; Kolbasova, Glafira; Razgon, Ilia; Semiletov, Igor (Peer reviewed; Journal article, 2021)
      Plastic pollution is globally recognised as a threat to marine ecosystems, habitats, and wildlife, and it has now reached remote locations such as the Arctic Ocean. Nevertheless, the distribution of microplastics in the ...

    • Nitrous Oxide Dynamics in the Siberian Arctic Ocean and Vulnerability to Climate Change 

      Wild, Birgit; Ray, Nicholas E.; Lett, Céline; Davies, Amelia Jane; Kirillova, Elena; Holmstrand, Henry; Klevantceva, Elizaveta; Osadchiev, Alexander; Gangnus, Ivan; Yakushev, Evgeniy; Kosmach, Denis; Dudarev, Oleg; Gustafsson, Örjan; Semiletov, Igor; Brüchert, Volker (Peer reviewed; Journal article, 2023)
      Nitrous oxide (N2O) is a strong greenhouse gas and stratospheric ozone-depleting substance. Around 20% of global emissions stem from the ocean, but current estimates and future projections are uncertain due to poor spatial ...

    • The Role of Coastal Yedoma Deposits and Continental Shelf Sediments in the Arctic Ocean Silicon Cycle 

      Ray, Nicholas E.; Martens, Jannik; Ajmar, Marco; Tesi, Tommaso; Yakushev, Evgeniy; Gangnus, Ivan; Strauss, Jens; Schirrmeister, Lutz; Semiletov, Igor; Wild, Birgit (Peer reviewed; Journal article, 2024)
      The availability of silicon (Si) in the ocean plays an important role in regulating biogeochemical and ecological processes. The Si budget of the Arctic Ocean appears balanced, with inputs equivalent to outputs, though it ...
