Grain Size Constraints on Glacial Circulation in the Southwest Atlantic [PDF]

Paleoceanography and Paleoclimatology, 2018
AbstractKnowledge of past deep‐ocean current speeds has the potential to inform our understanding of changes in the climate system on glacial‐interglacial timescales, because they may be used to help constrain changes in deep‐ocean circulation rates and pathways.
