The modern and glacial overturning circulation in the Atlantic ocean in PMIP coupled model simulations (2006, background): “Better constraints are obtained from Pa/Th data, which indicate a slowdown of the AMOC during the LGM as compared to the present climate by ca. 30% and probably less (McManus et al., 2004).”
History matching for exploring and reducing climate model parameter space using observations and a large perturbed physics ensemble (2013, methodology): “Paleoclimate records suggest that the AMOC has previously undergone major rapid fluctuations (McManus et al. 2004).”
Tree rings and ice cores reveal C-14 calibration uncertainties during the Younger Dryas (2008, positive): “Radiocarbon during the Younger Dryas Ocean circulation changes are hypothesized to control many climate sequences, especially the strong and rapid cooling in Greenland at the onset of YD, and there is evidence for changes in North Atlantic overturnin”
Sea-level probability for the last deglaciation: A statistical analysis of far-field records (2011, background): “The AMOC underwent a major abrupt intensification at that time (McManus et al., 2004; Stanford et al., 2006).”
The polar ocean and glacial cycles in atmospheric CO2 concentration (2010, background): “…warming during Greenland’s Bølling–Allerød (B/A) warm period and a resumption of Antarctic warming during Greenland’s Younger Dryas (YD) cold period. j ,The 231 Pa/ 230 ThactivityratioofaNorthAtlanticsedimentcore 20 suggestsa sharp reduction in North Atlantic export of subsurface water beginning17.”
The last deglaciation: timing the bipolar seesaw (2011, background): “When considering bipolar coupling during the deglaciation, division of climate in the North Atlantic into three stages (GS-2, B-A, and YD) may be too simplistic; we ﬁnd evidence that the sub-millennial climate transitions within the B-A (suggested to be linked to freshwater forcing events (Thornalle”
Deconstructing the Last Glacial termination: the role of millennial and orbital-scale forcings (2011, methodology): “North Atlantic OCE326-GGC5 (231)Pa/(230)Th (McManus et al., 2004) ( ) 200”
Lowering of glacial atmospheric CO2 in response to changes in oceanic circulation and marine biogeochemistry (2007, background): “This type of glacial ocean circulation changes is supported by proxy data for Atlantic meridional overturning [ McManus et al., 2004; Lynch-Stieglitz et al., 2007], and a dominance of low 13 C and 14 C Antarctic water in the glacial Atlantic ocean below 2–2.5 km depth [Duplessy et al., 1988; Curry ”
Will Greenland melting halt the thermohaline circulation? (2006, background): “While the convection in the Labrador Sea immediately affects the AMOC [Latif et al., 2006], the dense overflows are a product of the hydraulic system controlled by the GSR and their strength does not directly depend on deep convection in the Greenland Sea [ Mauritzen, 1996 ].”
Dansgaard‐Oeschger oscillations predicted in a comprehensive model of glacial climate: A “kicked” salt oscillator in the Atlantic (2014, neutral): “A reduction in strength of this magnitude accords with that based upon the use of the Pa/Th tracer of the kinematic strength of the deep western boundary undercurrent of the North Atlantic Basin [McManus et al., 2004].”
