Investigation of the controls on the cadmium isotope composition of modern marine sediments

Thesis

Cadmium (Cd) isotopes have provided insights into the biogeochemical cycling of Cd in the modern oceans, and may be used to provide information about past ocean chemistry. Cadmium is removed from seawater into marine sediments, but the isotopic composition of this output flux, and the processes that control the isotope composition of marine sediments, are not well understood. This lack of understanding is partly due to the currently unknown influence of Cd-sulphide formation on the isotopic ...
