Geochemical data were gained for short sediment cores from Maxwell Bay and Potter Cove (King George Island, Antarctica) in 2012 and 2013. We investigated the influence of different iron transport pathways and their effect on the early diagenetic cycling of this nutrient. The dataset includes pore water data (alkalinity, sulfate, Fe2+, NH4+) for 14 sites and solid phase data (including stable iron isotope data for sequentially extracted Fe pools) as well as pore water stable iron isotope data for two contrasting sites: one located at the glacier terminus and the other one at the discharge of a surficial oxic meltwater stream draining the ice-free Potter Peninsula.
