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, 2019-11-01)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 ... -
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 ... -
Hydrography in the Nordic Seas During Dansgaard-Oeschger Events 8-5
Sessford, Evangeline (Doctoral thesis, 2019-06-14)The modern rapidity of Arctic sea ice loss and rise in Arctic air and ocean temperatures is pushing research to understand mechanisms for abrupt climate fluctuations. Resolving the mechanisms of past abrupt changes is a ... -
A spatio-temporal reconstruction of sea-surface temperatures in the North Atlantic during Dansgaard-Oeschger events 5–8
Jensen, Mari Fjalstad; Nummelin, Aleksi; Nielsen, Søren B.; Sadatzki, Henrik; Sessford, Evangeline; Risebrobakken, Bjørg; Andersson, Carin; Voelker, Antje; Roberts, William H. G.; Born, Andreas (Journal article, 2017-08-24)Here we establish a spatio-temporal evolution of the sea-surface temperatures in the North Atlantic over Dansgaard Oeschger (DO) events 5–8 (c. 30–40 ka) using the proxy surrogate reconstruction method. Proxy data suggest ...
