      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 ...

Sakari; Šeirienė, Vaida; Winter, Hanna; Tzedakis, P. Chronis; Birks, Harry John Betteley (Peer reviewed; Journal article, 2019)
      The Eemian interglacial represents a natural experiment on how past vegetation with negligible human impact responded to amplified temperature changes compared to the Holocene. Here, we assemble 47 carefully selected Eemian ...

    • 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, 2018)
      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 ...

    • A high-resolution study of Holocene paleoclimatic and paleoceanographic changes in the Nordic Seas 

      Risebrobakken, Bjørg; Jansen, Eystein; Andersson, Carin; Mjelde, Eirik; Hevrøy, Kjersti (Peer reviewed; Journal article, 2003-03-26)
      High-resolution records from IMAGES core MD95-2011 in the eastern Norwegian Sea provide evidence for relatively large- and small-scale high-latitude climate variability throughout the Holocene. During the early and ...

    • Holocene trends in the foraminifer record from the Norwegian Sea and the North Atlantic Ocean 

      Andersson, Carin; Pausata, Francesco S. R.; Jansen, Eystein; Risebrobakken, Bjørg; Telford, Richard J. (Peer reviewed; Journal article, 2010-03-30)
      The early to mid-Holocene thermal optimum is a well-known feature in a wide variety of paleoclimate archives from the Northern Hemisphere. Reconstructed summer temperature anomalies from across northern Europe show a clear ...

    • Inception of the Northern European Ice Sheet due to contrasting ocean and insolation forcing 

      Risebrobakken, Bjørg; Dokken, Trond Martin; Otterå, Odd Helge; Jansen, Eystein; Gao, Yongqi; Drange, Helge (Peer reviewed; Journal article, 2007-01)
      About 115,000 years ago the last interglacial reached its terminus and nucleation of new ice sheet growth was initiated. Evidence from the northernmost Nordic Seas indicate that the inception of the last glacial was related ...
