SUMMARY:The biogeochemistry of redox-sensitive elements and the δ238U isotope system in the permanently euxinic Framvaren Fjord
DESCRIPTION:
A seminar by Otago Geology PhD student William Preston. 
The oxygen concentration of the Earth's ocean-atmosphere regimes has fluctuated numerous times throughout geological time, displaying an intrinsic link to the evolution of life on Earth.  
Through the utilisation of redox-sensitive elements and their isotope systems, as proxies for investigating oxygen depleted conditions from sedimentary archives, palaeo-environmental reconstructions can be conducted during times of server climatic disturbance. However, for the accurate and reliable deployment of such palaeo-environmental proxies, it is necessary to examine how redox-sensitive elements and their isotope systems behave in modern environments of varying oxygen depletion. 
Therefore, the distribution and behaviour of redox-sensitive elements and the uranium isotope system was examined in Framvaren Fjord, a highly oxygen depleted marine basin with conditions similar to Earth in the past.
