Here we provide dissolved inorganic nutrient data generated via the analysis of samples collected by autonomous instruments, in particular Remote Access Samplers (RAS) and associated sensor data (CTD-O2, PAR, Fluorescence, pH, pCO2). Data was collected within the frame of the AWI Frontiers in Arctic Marine Monitoring (FRAM) Programme and HAUSGARTEN LTO. A report is also provided, which includes basic data about the data, which are associated with two Polarstern expeditions; PS99 (grant AWI_PS99_0) and PS107 (AWI_PS107_05).
