TL;DR: This is the first set of consistently dated marine sediment cores enabling paleoclimate scientists to evaluate leads/lags between circulation and climate changes over vast regions of the Atlantic Ocean.
Journal ArticleDOI
Reversed flow of Atlantic deep water during the Last Glacial Maximum
César Negre,Rainer Zahn,Rainer Zahn,Alexander L. Thomas,Pere Masqué,Gideon M. Henderson,Gema Martínez-Méndez,Gema Martínez-Méndez,Ian Hall,José Luis Mas +9 more
TL;DR: It is shown that the basin-scale abyssal circulation of the Atlantic Ocean was probably reversed during the Last Glacial Maximum and was dominated by northward water flow from the Southern Ocean, and thus the direction of the deep ocean circulation.
Journal ArticleDOI
Contrasting multiproxy reconstructions of surface ocean hydrography in the Agulhas Corridor and implications for the Agulhas Leakage during the last 345,000 years
Gema Martínez-Méndez,Gema Martínez-Méndez,Rainer Zahn,Rainer Zahn,Ian Hall,Frank Peeters,Leopoldo D. Pena,Isabel Cacho,César Negre,César Negre +9 more
TL;DR: In this article, paired planktonic δ18O and Mg/Ca-derived sea surface temperature (SST) records from the Agulhas Corridor off South Africa display a progressive increase of SST during glacial periods of the last three climatic cycles.
Journal ArticleDOI

Spero,Claire Waelbroeck +25 more
TL;DR: In this article, more than 1700 δ13C observations of the benthic foraminifera genus Cibicides from late Holocene sediments (δ13CCibnat) are compiled and compared with newly updated estimates of the natural (preindustrial) water column δ 13C of dissolved inorganic carbon (´13CDICnat) as part of the international Ocean Circulation and Carbon Cycling (OC3) project.
Journal ArticleDOI
Changes in the advection of Antarctic Intermediate Water to the northern Chilean coast during the last 970 kyr
Gema Martínez-Méndez,Dierk Hebbeln,Mahyar Mohtadi,Frank Lamy,R. De Pol-Holz,D. Reyes-Macaya,Tim Freudenthal +6 more
TL;DR: In this article, the authors present records of benthic stable isotopes from sediments retrieved with the seafloor drill rig MARUM-MeBo at 956m water depth off northern Chile (GeoB15016, 27°29.48′S, 71°07.58′W) that extend back to 970 kyr.
