Atlantic Meridional Overturning Circulation and δ13C Variability During the Last Interglacial
Kessler, Augustin; Bouttes, Nathaelle; Roche, Didier M.; Ninnemann, Ulysses S; Galaasen, Eirik Vinje; Tjiputra, Jerry (Journal article; Peer reviewed, 2020)The Atlantic Meridional Overturning Circulation (AMOC) is thought to be relatively vigorous and stable during Interglacial periods on multimillennial (equilibrium) timescales. However, recent proxy (δ13C benthic) reconstructions ... -
Dynamics of spontaneous (multi) centennial‐scale variations of the Atlantic meridional overturning circulation strength during the last interglacial
Kessler, Augustin; Bouttes, Nathaelle; Roche, Didier M.; Ninnemann, Ulysses S; Tjiputra, Jerry (Peer reviewed; Journal article, 2020)Recent reconstructions of bottom water δ13C during the last interglacial (LIG) suggest short‐lived variability in the Atlantic meridional overturning circulation (AMOC). Spontaneous (multi) centennial‐scale variability of ... -
Evaluating the biological pump efficiency of the Last Glacial Maximum ocean using d13C
Morée, Anne; Schwinger, Jörg; Ninnemann, Ulysses S; Jeltsch-Thommes, Aurich; Bethke, Ingo; Heinze, Christoph (Peer reviewed; Journal article, 2021)Although both physical and biological marine changes are required to explain the 100 ppm lower atmospheric pCO2 of the Last Glacial Maximum (LGM, ∼21 ka) as compared to preindustrial (PI) times, their exact contributions ...
