At selected stations the bio-optical package was lowered to the depth of 240 m (or 20 m above the sea bottom if the depth was lower than 260 m) at 20 m/minute. The radiometric measurements were taken only during the day.\nParameters measured: \nSeaBird CTD (4 Hz frequency):\n- Temperature\n- Salinity\n- Pressure\n- PAR\n- Fluorescence \n- Oxygen\nSatlantic HyperOCR:\n- Upwelling radiance (Lu) - spectral\n- Downwelling irradiance (Ed) \u2013 spectral\n- Pressure\nHobiLabs Hydroscat:\n- Backscattering coefficient at 6 wavelengths (442, 488, 550, 589, 676, 850 nm)\n- Fluorescence (550, 676 nm)\n- Pressure\nWetLabs ac-9 (2 Hz frequency)\n- Light absorption coefficient at 9 wavelengths (412, 440, 488, 510, 532, 555, 650, 676, 715 nm)\n- Light attenuation

raw and calibrated data files were created on board, processed and quality controlled files (.dat and/or .csv) will be available by the end of 2016.\nOwner of instrument: CSIRO\nUnits:\nCTD data:
