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 ... -

Zhang, Zhongshi; Li, Xiangyu; Guo, Chuncheng; Otterå, Odd Helge; Nisancioglu, Kerim Hestnes; Tan, Ning; Contoux, Camille; Ramstein, Gilles; Feng, Ran; Otto-Bliesner, Bette L.; Brady, Esther C.; Chandan, Deepak; Richard Peltier, Peltier; Baatsen, Michiel L. J.; Von Der Heydt, Anna S.; Weiffenbach, Julia E.; Stepanek, Christian; Lohmann, Gerrit; Zhang, Qiong; Li, Qiang; Chandler, Mark A.; Sohl, Linda E.; Haywood, Alan M.; Hunter, Stephen J.; Tindall, Julia C.; Williams, Charles; Lunt, Daniel J.; Chan, Wing-Le; Abe-Ouchi, Ayako (Journal article; Peer reviewed, 2021)In the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2), coupled climate models have been used to simulate an interglacial climate during the mid-Piacenzian warm period (mPWP; 3.264 to 3.025 Ma). Here, we compare ... -
An oceanic perspective on Greenland’s recent freshwater discharge since 1850
Perner, Kerstin; Moros, Matthias; Otterå, Odd Helge; Blanz, Thomas; Schneider, Ralph R.; Jansen, Eystein (Journal article; Peer reviewed, 2019)Instrumental data evidence an accelerating freshwater release from Arctic sea ice export and the Greenland Ice Sheet over the past three decades causing cooling and freshening in the subpolar North Atlantic region. However, ... -
Using simulations of the last millennium to understand climate variability seen in palaeo-observations: Similar variation of Iceland-Scotland overflow strength and Atlantic Multidecadal Oscillation
Lohmann, Katja; Mignot, Juliette; Langehaug, Helene Reinertsen; Jungclaus, Johann H.; Matei, Daniela; Otterå, Odd Helge; Gao, Yongqi; Mjell, Tor Lien; Ninnemann, Ulysses Silas; Kleiven, Helga Flesche (Peer reviewed; Journal article, 2015-02-10)A recent palaeo-reconstruction of the strength of the Iceland–Scotland overflow during the last 600 years suggests that its low-frequency variability exhibits strong similarity with palaeo-reconstructions of the Atlantic ...
