Abstract:
Benthic foraminiferal studies suggest that deep Atlantic circulation during the Last Glacial Maximum was different from today. High-nutrient deep Southern Ocean Water penetrating far into the North Atlantic. Cibicidoides wuellerstorfi Cd/Ca results presented in this paper indicate that the glacial North Atlantic was enriched in dissolved Cd. NADW. High glacial Zn/Ca values in the same samples, are best explained by a substantially increased mixing with Zn-rich SOW. The cause was most likely a partial replacement of NADW by less dense Glacial North Atlantic Intermediate Water. (modified journ. abst.)
