| Antarctic Intermediate Water (AAIW) is an important conduit for nutrients to reach the nutrient-poor low-latitude ocean areas. In the Atlantic, it forms part of the return path of the Atlantic Meridional Overturning Circulation (AMOC). Despite the importance of AAIW, little is known about variations in its composition and signature during the prominent AMOC and climate changes of the last deglaciation. Here we reconstruct benthic foraminiferal Mg/Ca-based intermediate water temperatures (IWTMg/ca) and intermediate water neodymium (Nd) isotope compositions at submillennial resolution from unique sediment cores located at the northern tip of modern AAIW extent in the tropical W-Atlantic (850- and 1018-m water depth). Our data indicate a pronounced warming of... |
