• Consistent fluctuations in intermediate water temperature off the coast of Greenland and Norway during Dansgaard-Oeschger events 

      Sessford, Evangeline; Jensen, Mari Fjalstad; Tisserand, Amandine Aline; Muschitiello, Francesco; Dokken, Trond Martin; Nisancioglu, Kerim Hestnes; Jansen, Eystein (Peer reviewed; Journal article, 2019)
      Rapid warmings epitomize the Dansgaard-Oeschger events that are recorded in Greenland ice cores and imprinted in ocean sediment cores. While the abrupt climate changes appear connected to perturbations in sea ice and ocean ...
    • Consistently dated Atlantic sediment cores over the last 40 thousand years

      Rapid changes in ocean circulation and climate have been observed in marine-sediment and ice cores over the last glacial period and deglaciation, highlighting the non-linear character of the climate system and underlining ...
    • High resolution benthic Mg/Ca temperature record of the intermediate water in the Denmark Strait across D-O stadial-interstadial cycles 

      Sessford, Evangeline; Tisserand, Amandine Aline; Risebrobakken, Bjørg; Andersson, Carin; Dokken, Trond Martin; Jansen, Eystein (Peer reviewed; Journal article, 2019)
      Dansgaard‐Oeschger (D‐O) climate instabilities that took place during Marine Isotope Stage 3 are connected to changes in ocean circulation patterns and sea ice cover. Here we explore in detail the configuration of the water ...
    • Independent tephrochronological evidence for rapid and synchronous oceanic and atmospheric temperature rises over the Greenland stadial-interstadial transitions between ca. 32 and 40 ka b2k 

      Berben, Sarah Miche Patricia; Dokken, Trond Martin; Abbott, Peter M.; Cook, Eliza; Sadatzki, Henrik; Simon, Margit Hildegard; Jansen, Eystein (Journal article; Peer reviewed, 2020)
      Understanding the dynamics that drove past abrupt climate changes, such as the Dansgaard-Oeschger (DO) events, depends on combined proxy evidence from disparate archives. To identify leads, lags and synchronicity between ...
    • Insolation and Glacial Meltwater Influence on Sea‐Ice and Circulation Variability in the Northeastern Labrador Sea During the Last Glacial Period 

      Griem, Lisa; Voelker, Antje H.L.; Berben, Sarah Miche Patricia; Dokken, Trond Martin; Jansen, Eystein (Peer reviewed; Journal article, 2019)
      The variable amounts of ice rafted debris (IRD) and foraminifers in North Atlantic sediments are related to the abrupt, millennial‐scale alteration from Greenland stadials to interstadials during the last glacial period ...
    • A multi-decadal record of oceanographic changes of the past ~165 years (1850-2015 AD) from Northwest of Iceland 

      Simon, Margit Hildegard; Muschitiello, Francesco; Tisserand, Amandine Aline; Olsen, Are; Moros, Matthias; Perner, Kerstin; Bårdsnes, Siv Tone; Dokken, Trond Martin; Jansen, Eystein (Peer reviewed; Journal article, 2020)
      Extending oceanographic data beyond the instrumental period is highly needed to better characterize and understand multi-decadal to centennial natural ocean variability. Here, a stable isotope record at unprecedented ...
    • Tephra horizons identified in the western North Atlantic and Nordic Seas during the Last Glacial Period: Extending the marine tephra framework 

      Rutledal, Sunniva; Berben, Sarah Miche Patricia; Dokken, Trond Martin; Bilt, Willem van der; Cederstrøm, Jan Magne; Jansen, Eystein (Peer reviewed; Journal article, 2020)
      Geochemically distinct volcanic ash (tephra) deposits are increasingly acknowledged as a key geochronological tool to synchronize independent paleoclimate archives. Recent advances in the detection of invisible (crypto) ...
