    Description: Changes in heat transport associated with fluctuations in the strength of the Atlantic meridional overturning circulation (AMOC) are widely considered to affect the position of the Intertropical Convergence Zone (ITCZ), but the temporal immediacy of this teleconnection has to date not been resolved. Based on a high-resolution marine sediment sequence over the last deglaciation, we provide evidence for a synchronous and near-linear link between changes in the Atlantic interhemispheric sea surface temperature difference and continental precipitation over northeast Brazil. The tight coupling between AMOC strength, sea surface temperature difference, and precipitation changes over northeast Brazil unambiguously points to a rapid and proportional adjustment of the ITCZ location to past changes in the Atlantic meridional heat transport.

    Benthic oxygen isotope ratios from a transect of five gravity cores off NW Africa (2018)
    PANGAEA
    In:  Supplement to: Völpel, Rike; Mulitza, Stefan; Paul, A; Lynch-Stieglitz, Jean; Schulz, Michael (2019): Water Mass Versus Sea Level Effects on Benthic Foraminiferal Oxygen Isotope Ratios in the Atlantic Ocean During the LGM. Paleoceanography and Paleoclimatology, 34(1), 98-121, https://doi.org/10.1029/2018PA003359

    Description: Depth transects of benthic foraminiferal oxygen isotopes from the Atlantic Ocean show that glacial‐interglacial changes are larger at deep (〉 ~2000 m) than at intermediate water levels. Our model results suggest that the smaller changes in the upper 1000 m of the water column are a result of the glacial sea‐level lowering of about 120 m, leading to warmer temperatures of around 1 °C and hence a smaller glacial‐interglacial stable oxygen isotope difference. In contrast, a shoaling of the water‐mass boundary to ~2000 m water depth between the northern source and southern source water is accompanied by the expansion of a cold (close to the freezing point) southern source water in the abyssal ocean, increasing the oxygen isotope values of benthic foraminifera from the LGM in the deep Atlantic. These two effects explain the different amplitudes of glacial‐interglacial stable oxygen isotope differences in the upper and deeper water column of the Atlantic Ocean.
