Expansion of Antarctic Bottom Water driven by Antarctic warming in the last deglaciation

Antarctic Bottom Water progressively filled more of the deep Southern Ocean through the last deglaciation, potentially contributing to the increase in atmospheric CO₂, according to neodymium isotope records from the Weddell–Enderby Basin.

Low variability of the Atlantic Meridional Overturning Circulation throughout the Holocene

Combining sedimentary Pa/Th with ESM simulations allowed quantitative estimates of past AMOC largescale strengths. The AMOC reinvigorated after the last glacial, weakened during meltwater events and reached its stable state after ~6.5 ka BP.

Multi-proxy constraints on Atlantic circulation dynamics since the last ice age

The Atlantic meridional overturning circulation was shallow and weak during the Last Glacial Maximum, and water masses took time to adjust to circulation shifts during the Last Deglaciation, according to a reassessment of proxy records and model simulations.

Prevalent North Atlantic Deep Water during the Last Glacial Maximum and Heinrich Stadial 1

North Atlantic Deep Water formation was only moderately weaker than it is now during the last glacial period, even when freshwater inputs were high, according to an analysis of independent proxy records.
