The Southern Ocean plays an important role in the glacial climate with the exchange of CO2 between the ocean and the atmosphere. This research project will provide the first radiolarian records from the South Pacific sector of the Southern Ocean over the last glacial cycle and will help to refine our understanding of the changes in temperature and sea ice concentrations in this region. We will take advantage of improvements in mass spectrometry and methods to develop oxygen isotope analyses on marine biogenic silica (radiolarian skeletons). This has the potential to revolutionise the study of paleoclimate in the Southern Ocean and Antarctic margin where there is often no carbonate to analyse to develop age models for sedimentary cores.
