Dataset: GN01 Silicon Stable Isotopes The isotopic composition of dissolved silicon (δ30Si) has proven to be a powerful tool to better understand the marine Si cycle. The δ30Si of seawater carries information about DSi utilization in surface waters, the subsequent dissolution of sinking biogenic material as well as water mass mixing. This data set supplies information on the spatial distribution of isotopes of Si within water masses in the Arctic Ocean from the Bering Strait to the north pole. Profiles of silicon isotopes within silicic acid, δ30Si(OH)4, were obtained at a total of 15 stations on the GEOTRACES GN01 cruise For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.
