Lamy and co-authors used sediment records from the pelagic central and remote South Pacific Ocean, to reconstruct the strength of the Antarctic Circumpolar Current and shifts of the Southern Ocean frontal system over the past roughly 5.3 Myr…
This study is challenging the belief that the onset of the Antarctic Circumpolar Current was solely triggered by the opening and deepening of Southern Ocean Gateways.
Farmer and colleagues review the geochemical proxies based upon sedimentary isotope ratios of three abundant biologically mediated elements.
Horner and co-authors assess whether nine bioactive trace metals and their isotopes can be used as paleo-productivity proxies.
Abrupt climate changes in the past have been attributed to variations in Atlantic Meridional Overturning Circulation (AMOC) strength. Knowing the exact timing and magnitude of the AMOC shift is important […]
Which paleo information are traced by the imprint neodymium isotopic signatures (εNd) in the different archives: paleo circulation or paleo erosion? The scientific debate on this issue is opened for […]
Analyses of seawater chromium (Cr) concentrations and isotopes in diverse marine environments (Arctic, Pacific, and Atlantic Oceans) reveal a strong correlation between Cr isotope composition (δ53Cr) and Cr concentration. High […]
Xie and co-authors (2015, see reference below) report vertical profiles of dissolved cadmium (Cd) in the western South Atlantic Ocean (GEOTRACES section GA02), which show nutrient-like distributions similar to those […]
