Abstract

Atlantic Meridional Overturning Circulation (AMOC) plays an important role in the global climate through its regulation of northward heat transport in the surface ocean and its infl uence upon carbon storage in the deep ocean. Despite the efforts of both biological proxy reconstructions and modelling studies, exactly how this Atlantic overturning has evolved with past changes in the climate remains uncertain. In an effort to improve the understanding of how AMOC has varied during the Quaternary, this thesis presents measurements of neodymium (Nd) isotopes - a quasi-conservative water mass tracer - made on uncleaned foraminifera and fi sh debris from cores throughout the Atlantic Ocean covering time periods from 2.1 million years ago to the present day.
