waters, interesting because the growth of Southern Ocean phytoplankton influences atmospheric carbon dioxide levels and thus global climate. We will produce the first dataset on the isotopic composition of [...] (Antarctica), east to the Kerguelen Plateau, and then up to Cape Town (South Africa). We will also measure dissolved iron, nutrient, and chlorophyll concentrations and the size of the diatom, Fragilariopsis [...] kerguelensis. These data will improve our understanding of the nutrient use proxies by revealing the spatial scale over which variations in the isotopic composition of nutrients occur and how isotopic
