      The main objectives of this work were the acquisition of new data on floating marine macro litter (FMML) and natural floating objects in the Arctic seas, an initial assessment of the level of pollution by FMML and an ...

    • Microplastics distribution in the Eurasian Arctic is affected by Atlantic waters and Siberian rivers 

      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 ...

    • Surface microplastics in the Kara Sea: from the Kara Gate to the 83°N
