      Lannuzel, Delphine; Tedesco, Letizia; Leeuwe, Maria van; Campbell, Karley; Flores, Hauke; Delille, Bruno; Miller, Lisa; Stefels, Jacqueline; Assmy, Philipp; Bowman, Jeff; Brown, Kristina; Castellani, Giulia; Chierici, Melissa; Crabeck, Odile; Damm, Ellen; Else, Brent; Fransson, Agneta; Fripiat, Francois; Geilfus, Nicolas-Xavier; Jacques, Caroline; Jones, Elizabeth; Kaartokallio, Hermanni; kotovitch, marie; Meiners, Klaus M.; Moreau, Sebastien; Nomura, Daiki; Peeken, Ilka; Rintala, Janne-Markus; Steiner, Nadja; Tison, Jean-Louis; Vancoppenolle, Martin; Linden, Fanny Van der; Vichi, Marcello; Wongpan, Pat (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-27)
      The Arctic sea-ice-scape is rapidly transforming. Increasing light penetration will initiate earlier seasonal primary production. This earlier growing season may be accompanied by an increase in ice algae and phytoplankton biomass, augmenting the emission of dimethylsulfide and capture of carbon dioxide. Secondary production may also increase on the shelves, although the loss of sea ice exacerbates ...

    • Sources and sinks of methane in sea ice: Insights from stable isotopes 

      Jacques, Caroline; Sapart, Celia J.; Fripiat, François; Carnat, Gauthier; Zhou, Jiayun; Delille, Bruno; Röckmann, Thomas; van der Veen, Carina; Niemann, Helge; Haskell, Tim; Tison, Jean-Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-27)
      We report on methane (CH<sub>4)</sub> stable isotope (d<sup>13</sup>C and d<sup>2</sup> H) measurements from landfast sea ice collected near Barrow (Utqiagvik, Alaska) and Cape Evans (Antarctica) over the winter-to-spring transition. These measurements provide novel insights into pathways of CH<sub>4</sub> production and consumption in sea ice. We found substantial differences between the two ...
