I8S

The I8S hydrographic survey consisting of LADCP/CTD/rosette sections, bio-optical casts, trace metals rosette sections, underway shipboard ADCP, Argo Float deployments in the southern Indian Ocean was carried out in February and March 2007. The R/V Revelle departed Dunedin, New Zealand on 4 February 2007. A total of 88 stations were occupied. 88 LADCP/CTD/Rosette casts, 39 Trace Metals Rosette casts, 25 bio-optical casts were made, and 14 ARGO Floats were deployed from 15 February to 14 March. 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 17 March 2007.
