Tracing past and present Arctic geochemical cycling and its link to climate change using neodymium isotopes
… changes in both climate and ocean circulation. Neodymium isotope ratios (εNd) have been used extensively as a tracer of continental crustal evolution and in sediment and seawater provenance studies. In this thesis εNd is measured on a suite of marine and terrestrial sediment and waters, broadly …

A study of the photon decay modes of the giant dipole resonance in even-A neodymium isotopes
This experiment measured the elastic and inelastic photon scattering cross sections into the ground and first excited state across the isotopic chain 142,146,148,150Nd between the energies of 12 and 18 MeV, spanning the peak of the Isovector Giant Dipole Resonance. Inelastic scattering into the …

Orbital-scale fluctuations in continental weathering flux and continental ice-volume during greenhouse and icehouse climate intervals : evidence from oxygen and neodymium isotopes
Rapid changes in global and local climate and weather, noticeable over our lifetimes, have spurred heated public and political debate over the cause of these climatic changes, whether or not we can reverse, stop or slow down this process, and how to create adequate models that can predict Earth's …

Documenting the Origin of Compositional Diversity of Subduction Zone Magmatism, Alicudi, Aeolian Arc (Southern Tyrrhenian Sea, Italy) Using in situ Plagioclase Data
… rock major and trace elements and strontium/neodymium isotopes, and plagioclase textural types, major and trace elements, and strontium isotopes; numerical modeling was also conducted. Integration of these data suggests that recharge, assimilation, storage at different levels below the …

Reconstructing atmospheric changes in Monsoon regions using eolian dust
… demonstrate the feasibility of using radiogenic neodymium isotopes (143Nd/144Nd) at IODP Site U1430 in the Sea of Japan to fingerprint the provenance of eolian material at the core site from Asian dust sources. I then generate a 143Nd/144Nd record from isolated eolian material over the last 200 …

Marine cycling of neodymium in the South Atlantic and the Southern Oceans
Neodymium (Nd) isotopes have been used as a proxy to trace both modern and palaeo-ocean circulation of the deep ocean which is an important factor controlling the climate. Although there has been widespread utilisation of Nd isotopes as a proxy, the marine cycling of Nd is not fully understood. …
