    • Buoyancy forcing: A key driver of northern North Atlantic sea surface temperature variability across multiple timescales 

      Risebrobakken, Bjørg; Jensen, Mari Fjalstad; Langehaug, Helene R.; Eldevik, Tor; Sandø, Anne Britt; Li, Camille; Born, Andreas; McClymont, Erin Louise; Salzmann, Ulrich; De Schepper, Stijn (Journal article; Peer reviewed, 2023)
      Analyses of observational data (from year 1870 AD) show that sea surface temperature (SST) anomalies along the pathway of Atlantic Water transport in the North Atlantic, the Norwegian Sea and the Iceland Sea are spatially ...

    • Early Pliocene onset of modern Nordic Seas circulation related to ocean gateway changes 

      De Schepper, Stijn; Schreck, Michael; Beck, Kristina Marie; Matthiessen, Jens; Fahl, Kirsten; Mangerud, Gunn (Peer reviewed; Journal article, 2015-10-28)
      The globally warm climate of the early Pliocene gradually cooled from 4 million years ago, synchronous with decreasing atmospheric CO2 concentrations. In contrast, palaeoceanographic records indicate that the Nordic Seas ...

    • Late Neogene dinoflagellate cyst and acritarch biostratigraphy for Ocean Drilling Program Hole 642B, Norwegian Sea 

      De Schepper, Stijn; Beck, Kristina Marie; Mangerud, Gunn (Peer reviewed; Journal article, 2017-01)
      The Arctic is a critical region in the current and past global climate system. One major challenge for investigating the geological history of the Arctic is the establishment of a rigorous chronology. To get better insights ...

    • Lessons from a high-CO2 world: an ocean view from  ∼ 3 million years ago 

      McClymont, Erin L.; Ford, Heather; Ho, Sze Ling; Tindall, Julia C.; Haywood, Alan M.; Alonso-Garcia, Montserrat; Bailey, Ian; Berke, Melissa A.; Littler, Kate; Patterson, Molly O.; Petrick, Benjamin; Peterse, Francien; Ravelo, Ana Christina; Risebrobakken, Bjørg; De Schepper, Stijn; Swann, George E. A.; Kaustubh, Thirumalai; Tierney, Jessica E; Van der Weijst, Carolien; white, sarah; Abe-Ouchi, Ayako; Baatsen, Michiel L. J.; Brady, Esther C.; Chan, Wing-Le; Chandan, Deepak; Ran, Feng; Guo, Chenchen Guo; von der Heydt, Anna S.; Stephen, Hunter; Xiangyi, Li; Lohmann, Gerrit; Nisancioglu, Kerim Hestnes; Otto-Bliesner, Bette L.; Peltier, Richard W.; Stepanek, Christian; Zhang, Zhongshi (Journal article; Peer reviewed, 2020)
      A range of future climate scenarios are projected for high atmospheric CO2 concentrations, given uncertainties over future human actions as well as potential environmental and climatic feedbacks. The geological record ...

    • Limited exchange between the deep Pacific and Atlantic oceans during the warm mid-Pliocene and Marine Isotope Stage M2 “glaciation” 

      Braaten, Anna Hauge; Jakob, Kim A.; Ho, Sze Ling; Friedrich, Oliver; Galaasen, Eirik Vinje; De Schepper, Stijn; Wilson, Paul; Meckler, Anna Nele (Journal article; Peer reviewed, 2023)
      The Piacenzian stage (3.6–2.6 Ma) of the Pliocene is the most recent period where Earth experienced sustained intervals of global warmth analogous to predicted near-future climates. Despite considerable efforts to characterize ...

    • Northern hemisphere glaciation during the globally warm early late Pliocene 

      De Schepper, Stijn; Groeneveld, Jeroen; Naafs, B. David A.; Van Renterghem, Cédéric; Hennissen, Jan; Head, Martin J.; Louwye, Stephen; Fabian, Karl (Peer reviewed; Journal article, 2013-12-12)
      The early Late Pliocene (3.6 to ,3.0 million years ago) is the last extended interval in Earth’s history when atmospheric CO2 concentrations were comparable to today’s and global climate was warmer. Yet a severe global ...

    • The potential of sedimentary ancient DNA for reconstructingpast sea ice evolution 

      De Schepper, Stijn; Ray, Jessica Louise; Skaar, Katrine Sandnes; Sadatzki, Henrik; Ijaz, Umer Zeeshan; Stein, Ruediger; Larsen, Aud (Peer reviewed; Journal article, 2019-06-24)
      Sea ice is a crucial component of the Arctic climate system, yet the tools to document the evolution of sea ice conditions onhistorical and geological time scales are few and have limitations. Such records are essential ...
