Global ocean paleoredox

Finally, because the Mo ocean budget should be strongly sensitive to bottom water redox conditions, particularly perturbations associated with expanded deep sea anoxia, determination of Mo concentrations or their variations in ancient seawater, via sedimentary proxies, has been proposed as an indicator of global ocean paleoredox change (e.g., Emerson and Huested 1991). 

Although current efforts are focused on global ocean paleoredox, the Mo stable isotope system should also prove useful in other oceanographic and environmental applications and in geobiological research. Such possibilities, while as yet unexplored, are previewed hriefiy below. 

Molybdenum Isotope Ratios and Global Ocean Paleoredox... 

A particularly appealing aspect of paleoredox proxies based on isotope ratios of metals is the possibility of interpreting records of global redox conditions in the oceans or atmosphere, as opposed to the local snapshots in time and space...
