Cruise FK200126 was the first ROV exploration of the Bremer canyon systems, Mount Gabi seamount, and nearby continental margins located in the all-important yet poorly studied Southern Ocean offshore SW Australia, and revisited the Perth Canyon in the SE Indian Ocean which represents only the second ROV exploration of that area. The cruise focused on the collection of deep-water corals for post-cruise geochemical studies to reconstruct long-term environmental changes in this region, together with comprehensive characterisation of their present-day environments including physical and chemical oceanography, canyon geomorphology and geology, bathymetric mapping, faunal descriptions, and the first high resolution video imaging of these previously unexplored deep-water habitats. The NetCDF file contains CTD data and seawater carbonate parameters measured from seawater samples collected on board the SOI Falkor between 2020-01-26T09:18:56 and 2020-02-20T21:32:29, by 12-L Niskin bottles. Temperature and Salinity were measured using a SBE-911plus CTD, Dissolved Oxygen using a SBE-43 DO sensor and Fluorescence by a Wet Labs ECO-FLNTU; Total Alkalinity was measured using a Mettler-Toledo T50 with Rondolino autosampler; DIC was measured using an Apollo SciTech Dissolved Inorganic Carbon analyser; pH, aragonite and calcite saturation states were calculated using version 1.1 of CO2SYS for MATLAB’.
