The I8S hydrographic survey consisting of LADCP/CTD/rosette sections, bio-optical casts, underway shipboard ADCP, Argo Float deployments in the southern Indian Ocean was carried out in February and March 2016. The R/V Revelle departed Fremantle, Australia on 8 February 2016. A total of 83 stations were occupied. Water samples (up to 36 depths) and CTD data were collected on each LADCP/CTD/rosette cast in most cases to within 10-20 meters of the bottom. Salinity, dissolved oxygen and nutrient samples were analyzed for up to 36 water samples from each cast of the principal LADCP/CTD/rosette program. Water samples were also measured for Total DIC, Total Alkalinity, CFCs and CDOM, and samples were collected for DOC, POC, Helium/Tritium, and 13C. Underway surface pCO2, temperature, conductivity, dissolved oxygen, Fluorometer, meteorological and multibeam acoustical bathymetric measurements were made. The cruise ended in Fremantle, Australia on 16 March 2016.
