  • 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 (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 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 ...
  • Dansgaard-Oeschger and Heinrich event temperature anomalies in the North Atlantic set by sea ice, frontal position and thermocline structure 
    Pedro, J.B.; Andersson, Carin; Vettoretti, G.; Voelker, A.H.L.; Waelbroeck, C.; Dokken, Trond Martin; Jensen, Mari Fjalstad; Rasmussen, S.O.; Sessford, Evangeline; Jochum, M.; Nisancioglu, Kerim Hestnes (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We use eighteen timescale-synchronised near-surface temperature reconstructions spanning 10–50 thousand years before present to clarify the regional expression of Dansgaard-Oeschger (D-O) and Heinrich (H) events in the ...
  • Large changes in sea ice triggered by small changes in Atlantic water temperature 
    Jensen, Mari Fjalstad; Nisancioglu, Kerim Hestnes; Spall, Michael A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The sensitivity of sea ice to the temperature of inflowing Atlantic water across the Greenland–Scotland Ridge is investigated using an eddy-resolving configuration of the Massachusetts Institute of Technology General ...
  • Transient Increase in Arctic Deep-Water Formation and Ocean Circulation under Sea Ice Retreat 
    Bretones, Anais Magali; Nisancioglu, Kerim Hestnes; Jensen, Mari Fjalstad; Brakstad, Ailin; Yang, Shuting (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Abstract While a rapid sea ice retreat in the Arctic has become ubiquitous, the potential weakening of the Atlantic meridional overturning circulation (AMOC) in response to global warming is still under debate. As deep ...
