    • Fingerprint of Climate Change on Southern Ocean Carbon Storage 

      Wright, R.M.; Le Quéré, Quere; Mayot, N.; Olsen, Are; Bakker, D.C.E. (Journal article; Peer reviewed, 2023)
      The Southern Ocean plays a critical role in the uptake, transport, and storage of carbon by the global oceans. It is the ocean's largest sink of CO2, yet it is also among the regions with the lowest storage of anthropogenic ...
    • Global Ocean Sediment Composition and Burial Flux in the Deep Sea 

      Hayes, Christopher T.; Costa, Kassandra M.; Anderson, Robert F.; Calvo, Eva; Chase, Zanna; Demina, Ludmila L.; Dutay, Jean-Claude; German, Cristopher R.; Heimbürger-Boavida, Lars-Eric; Jaccard, Samuel L.; Jacobel, Allison; Kohfeld, Karen E.; Kravchishina, Marina D.; Lippold, Jörg; Mekik, Figen; Missiaen, Lise; Pavia, Frank; Paytan, Adina; Pedrosa-Pamies, Rut; Petrova, Mariia V.; Rahman, Shaily; Robinson, Laura F.; Roy-Barman, Matthieu; Sanchez-Vidal, Anna; Shiller, Alan M.; Tagliabue, Alessandro; Tessin, Allyson; van Hulten, Marco Marinus Peter; Zhang, Jing (Journal article; Peer reviewed, 2021)
      Quantitative knowledge about the burial of sedimentary components at the seafloor has wide-ranging implications in ocean science, from global climate to continental weathering. The use of 230Th-normalized fluxes reduces ...
    • How Is the Ocean Anthropogenic Carbon Reservoir Filled? 

      Davila, Xabier; Gebbie, Geoffrey; Brakstad, Ailin; Lauvset, Siv Kari; McDonagh, Elaine Louise; Schwinger, Jörg; Olsen, Are (Journal article; Peer reviewed, 2022)
      About a quarter of the total anthropogenic CO2 emissions during the industrial era has been absorbed by the ocean. The rate limiting step for this uptake is the transport of the anthropogenic carbon (Cant) from the ocean ...
    • Magnitude and Origin of the Anthropogenic CO2 Increase and the 13C Suess Effect in the Nordic Seas since 1981 

      Olsen, Are; Abdirahman, Omar M.; Bellerby, Richard G. J.; Johannessen, Truls; Ninnemann, Ulysses Silas; Brown, Kelly R.; Olsson, K. Anders; Olafsson, Jon; Nondal, Gisle; Kivimäe, Caroline; Kringstad, Solveig; Neill, Craig; Olafsdottir, Solveig (Peer reviewed; Journal article, 2006-09-29)
      This study evaluates the anthropogenic changes of CO2 (∆Cant) and δ13C (∆δ13Cant) in the Nordic seas, the northern limb of the Atlantic Meridional Overturning Circulation, that took place between 1981 and 2002/03. The ...
