Oceanographic research tools and themes

At Bristol our studies focus on reconstructing the conditions and changes of Earth’s oceans and climate both in the past and at the present day by using a range of geochemical tools.

Our main research themes include:

  • Silicon and it’s isotopes
    ***.nutrient utilisation proxy etc***

  • U-series isotopes
    ***Radiometric dating, continental inputs?, fluxes of different chemical components to the seafloor, changes in ocean circulation***

  • Deep water corals
    Fossilised specimens provide a record of the chemistry of the seawater in which they grew, allowing inferences about past ocean circulation to be made. In addition, the application of U-series dating techniques enables the history of coral population dynamics can be determined.

  • Trace metal cycling
