Description
The231Pa/230Th method is a promising tool to reconstruct Ocean circulation over the past Glacial-Interglacial cycle. However, marine particle flux may constrain the applicability of this ratio as a direct quantitative proxy for the strength of Atlantic Meridional Overturning Circulation (AMOC) by influencing the fractionation between the in situ produced231Pa and230Th in ocean water. Here we present231Pa/230Th down-core profiles from high particle flux areas off Namibia and Senegal covering the...[Show more]
