Atlantic circulation changes across a stadial-interstadial transition
Waelbroeck, Claire; Tjiputra, Jerry; Guo, Chuncheng; Nisancioglu, Kerim Hestnes; Jansen, Eystein; Vazquez Riveiros, Natalia; Toucanne, Samuel; Eynaud, Frederique; Rossignol, Linda; Dewilde, Fabien; Marchès, Elodie; Lebreiro, Susana; Nave, Silvia (Journal article; Peer reviewed, 2023)We combine consistently dated benthic carbon isotopic records distributed over the entire Atlantic Ocean with numerical simulations performed by a glacial configuration of the Norwegian Earth System Model with active ocean ... -
Behaviourally modern humans in coastal southern Africa experienced an increasingly continental climate during the transition from Marine Isotope Stage 5 to 4
Göktürk, Ozan Mert; Simon, Margit Hildegard; Sobolowski, Stefan Pieter; Zhang, Zhongshi; van der Bilt, Willem Godert Maria; Mørkved, Pål Tore; D’Andrea, William J.; Niekerk, Karen Loise van; Henshilwood, Christopher Stuart; Armitage, Simon James; Jansen, Eystein (Journal article; Peer reviewed, 2023-07-25)Unravelling evolution-by-environment interactions on the gut microbiome is particularly relevant considering the unprecedented level of human-driven disruption of the ecological and evolutionary trajectories of species. ... -
A continuous tephrostratigraphic record from the Labrador Sea spanning the last 65 ka
Rutledal, Sunniva; Haflidason, Haflidi; Berben, Sarah Miche Patricia; Griem, Lisa; Jansen, Eystein (Journal article; Peer reviewed, 2020)Volcanic ash preserved in marine sediment sequences is key for independent synchronization of palaeoclimate records within and across different climate archives. Here we present a continuous tephrostratigraphic record from ... -
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 M.P.; 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 (Journal article; Peer reviewed, 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 (Journal article; Peer reviewed, 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 ... -
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, ... -
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 (Journal article; Peer reviewed, 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) ...
