    • Cancellation of the precessional cycle in δ18O records during the Early Pleistocene 

      Morée, Anne; Sun, Tianyi; Bretones, Anaïs; Straume, Eivind Olavson; Nisancioglu, Kerim Hestnes; Gebbie, Geoffrey (Journal article; Peer reviewed, 2021)
      The dominant pacing of glacial‐interglacial cycles in deep‐ocean δ18O records changed substantially during the Mid‐Pleistocene Transition. The precessional cycle (∼23 ky) is absent during the Early Pleistocene, which we ...

    • Evaluating the biological pump efficiency of the Last Glacial Maximum ocean using δ13C 

      Morée, Anne; Schwinger, Jörg; Ninnemann, Ulysses S; Jeltsch-Thommes, Aurich; Bethke, Ingo; Heinze, Christoph (Journal article; Peer reviewed, 2021)
      Although both physical and biological marine changes are required to explain the 100 ppm lower atmospheric pCO2 of the Last Glacial Maximum (LGM, ∼21 ka) as compared to preindustrial (PI) times, their exact contributions ...

    • A Last Glacial Maximum forcing dataset for ocean modelling 

      Morée, Anne; Schwinger, Jörg (Journal article; Peer reviewed, 2020)
      Model simulations of the Last Glacial Maximum (LGM; ∼ 21 000 years before present) can aid the interpretation of proxy records, can help to gain an improved mechanistic understanding of the LGM climate system, and are ...

    • Ocean biogeochemistry in the Norwegian Earth System Model version 2 (NorESM2) 

      Tjiputra, Jerry; Schwinger, Jörg; Bentsen, Mats; Morée, Anne; Gao, Shuang; Bethke, Ingo; Heinze, Christoph; Goris, Nadine; Gupta, Alok Kumar; He, Yan-Chun; Oliviè, Dirk Jan Leo; Seland, Øyvind; Schulz, Michael (Journal article; Peer reviewed, 2020)
      The ocean carbon cycle is a key player in the climate system through its role in regulating the atmospheric carbon dioxide concentration and other processes that alter the Earth's radiative balance. In the second version ...

    • The role of the Southern Ocean in past global biogeochemical cycling 

      Morée, Anne (Doctoral thesis, 2020-04-27)
      This thesis describes several recent advances on the role of the Southern Ocean in past global biogeochemical cycling. We focus on the ocean of the Last Glacial Maximum (LGM) and the Pleistocene epoch and apply proxies of ...

    • Southern Ocean controls of the vertical marine δ13C gradient – a modelling study 

      Morée, Anne; Schwinger, Jörg; Heinze, Christoph (Peer reviewed; Journal article, 2018-12-04)
      δ 13 C, the standardised 13C/12C ratio expressed in per mille, is a widely used ocean tracer to study changes in ocean circulation, water mass ventilation, atmospheric pCO2, and the biological carbon pump on timescales ...
