Dataset abstract Nutrient concentrations (µmol/L): NOx, nitrate, nitrite, ammonium (NH 4 ), phosphate (PO 4 ) and silicic acid (Si), were measured in samples of seawater. Samples were collected from CTD and trace metal rosette deployments, as well as from the underway water supply on board, then analysed by flow injection following certified standards. This data was collected to support physical, chemical and biological oceanography studies conducted during the Antarctic Circumnavigation Expedition (ACE).
