Uncertainties persist in the understanding of the Atlantic meridional overturning circulation
and its response to external perturbations such as freshwater or radiative forcing. Abrupt …

Proxy reconstructions from deep ocean sediments have helped to shape our understanding
of the role of the global overturning circulation in past climate change. Neodymium (Nd) …

Understanding the role of sediment-water interactions in the oceanic cycling of neodymium
(Nd) isotopes is essential for its reliable use as a modern and palaeoceanographic tracer of …

Abstract Approximately 1,250,000 to 700,000 years ago, the pacing of glacial-interglacial
cycles changed from 41,000 years to∼ 100,000 years, a shift known as the 'Mid-Pleistocene …

The global overturning ocean circulation plays a key role in global climate by distributing
heat around the Earth and by triggering or amplifying major climate changes. Neodymium …

Determining past changes in ocean circulation on the Antarctic margin is important for
understanding the interactions between climate, circulation, and ice sheet retreat. However …

Radiogenic lead (Pb) and neodymium (Nd) isotope compositions extracted from authigenic
phases in marine sediments are sensitive tracers to reconstruct past ocean circulation and …

Increased deep ocean carbon storage is often invoked as the major sink for lower
atmospheric CO2 concentrations during past ice ages. In order to improve the …

The neodymium (Nd) isotopic composition of seawater is a widely used ocean circulation
tracer. However, uncertainty in quantifying the global ocean Nd budget, particularly …

Determining the factors controlling the neodymium (Nd) isotopic compositions (expressed as
ε Nd) and rare earth element (REE) concentrations of rivers is imperative to improve our …
