    • 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 ...

    • Meridional Ocean Carbon Transport 

      Aldama-Campino, Aitor; Fransner, Filippa; Ödalen, Malin; Groeskamp, Sjoerd; Yool, Andrew; Döös, Kristofer; Nycander, Jonas (Journal article; Peer reviewed, 2020)
      The ocean's ability to take up and store CO2 is a key factor for understanding past and future climate variability. However, qualitative and quantitative understanding of surface-to-interior pathways, and how the ocean ...

    • Preformed Properties for Marine Organic Matter and Carbonate Mineral Cycling Quantification 

      Carter, Brendan R.; Feely, Richard A.; Lauvset, Siv Kari; Olsen, Are; DeVries, Tim; Sonnerup, Rolf E. (Journal article; Peer reviewed, 2021)
      We estimate preformed ocean phosphate, nitrate, oxygen, silicate, and alkalinity by combining a reconstruction of ventilation pathways in the ocean interior with estimates of submixed layer properties. These new preformed ...

    • Quantifying Errors in Observationally Based Estimates of Ocean Carbon Sink Variability 

      Gloege, Lucas; McKinley, Galen A.; Landschützer, Peter; Fay, Amanda R.; Frölicher, Thomas L.; Fyfe, John; Ilyana, Tatiana; Jones, Stephen Daniel; Lovenduski, Nicole; Rodgers, Keith B.; Schlunegger, Sarah; Takano, Yohei (Journal article; Peer reviewed, 2021)
      Reducing uncertainty in the global carbon budget requires better quantification of ocean CO2 uptake and its temporal variability. Several methodologies for reconstructing air-sea CO2 exchange from pCO2 observations indicate ...

    • Reconciling Observation and Model Trends in North Atlantic Surface CO2 

      Lebehot, Alice; Halloran, Paul R.; Watson, Andrew J.; McNeall, Doug; Ford, David A; Landschützer, Peter; Lauvset, Siv Kari; Schuster, Ute (Peer reviewed; Journal article, 2019)
      The North Atlantic Ocean is a region of intense uptake of atmospheric CO2. To assess how this CO2 sink has evolved over recent decades, various approaches have been used to estimate basin‐wide uptake from the irregularly ...
