Project information
Project aim
We investigate how the ocean basins surrounding Antarctica became wider and deeper over time as the Gondwanaland super-continent drifted apart. Our seafloor age-depth maps use plate tectonic reconstructions with sedimentary/fossil records to help us better understand changes to the Southern Ocean environment, an important part of our global climate system.
