The global ocean overturning circulation is a major means of distributing heat around the
Earth, and an important trigger or amplifier of climate change. This study presents a 1.5-Myr …

The causes of the Mid-Pleistocene Transition, the shift from∼ 41-ky to 100-ky interglacial–
glacial cycles and more intense ice ages, remain intensely debated, as this fundamental …

Our understanding of past ocean-climate dynamics is informed by multiple paleocirculation
proxies including δ 13 C, 231 Pa/230 Th, and radiogenic neodymium isotopes (ε Nd). Of …

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 …

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 …

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

Limited constraints on the variability of the deep‐water production in the Labrador Sea
complicate reconstructions of the strength of the Atlantic Meridional Overturning Circulation …

Neodymium (Nd) isotope ratios are potentially valuable for paleo‐ocean circulation
reconstructions because they trace water‐mass transport and mixing in the present‐day …

Paleoceanographic studies are crucial for understanding the role of the ocean and its
circulation in the Earth's climate system. The patterns of the circulation can vary widely …

抄録 Neodymium (Nd) isotopic compositions of ferromanganese (Fe–Mn) crusts, bulk
sediment leachates, foraminiferal Fe–Mn hydroxides, biogenic apatite, and deep-sea corals …
