No change in the neodymium isotope composition of deep water exported from the North Atlantic on glacial-interglacial time scales
Quantifying past circulation is a vital part of testing our understanding of the modern and future climate system. The isotopic composition of neodymium (Nd) in marine precipitates has considerable promise as a recorder of past circulation patterns, but its robust application requires knowledge of t...
