Biogenic silicate concentration in sea water samples, collected from the CTD in the Southern Ocean during the austral summer of 2016/2017, on board the Antarctic Circumnavigation Expedition.

<strong>Dataset abstract</strong> Biogenic Silicate (Bsi) concentration (µmol/L) in seawater data. Water samples were collected from CTD rosette deployments, filtered on board and then analysed by flow injection following appropriate digestion. This data supports chemical and biological oceanography studies conducted during the Antarctic Circumnavigation Expedition. <strong>Dataset contents</strong> ace_biogenic_silicate_concentration_in_seawater_ctd.csv, data file, comma-separated values ace_biogenic_silicate_concentration_in_seawater_ctd_visual_summary.png, metadata, portable network graphics data_file_header.txt, metadata, text format README.md, metadata, text format All missing values where no data point exists from lack of sample, have been set to NaN. <strong>Dataset license</strong> This biogenic silica concentration dataset is made available under the Creative Commons Attribution 4.0 International License (CC BY 4.0) whose full text can be found at https://creativecommons.org/licenses/by/4.0/
