This dataset contains the UNCALIBRATED Conductivity-Temperature-Depth (CTD) data collected on Southern Surveyor voyage SS 11/2004. The voyage took place in the Coral Sea and the Pacific Ocean between 27-Oct-2004 to 23-Nov-2004. NO HYDROCHEMISTS WERE ON THIS VOYAGE SO this UNCALIBRATED ctd dataset has been processed as far as possible. IT will NOT be included in the processed data delivered via Data Trawler. Notes re the CTD averaged data files for ss2004/06 & 11 ======================================================= The dataset includes both 'normal' (Avg.nc) and 'ToYo' (Avt.n) averaged files. General comments: * Both datasets have been subjected to basic QC (removal of spikes), * The temperature data is accurately calibrated. * Salinity uses the manufacturer's conductivity calibration, as no calibration samples were collected during the voyage. This data should not therefore be used for serious oceanographic calculations. * An arbitrary calibration was applied to the transmission data, giving it a range of 0 - 100 (%) in air The 'Normal' averaged files: * Have a 2 dB averaging interval. * Only include the downcast data * Pressure reversals have been removed. The ToYo files have the following attributes: * Averaging interval = 0.5dB (or 10 secs, if the package stays within a particular depth bin for an interval > 10 secs) * Pressure reversals are not removed. * The profiles may include out-of-water or 'pumps off' data * The files include Lat, Long and depth, but the only non-NaN values are for the start, bottom & end of the cast. This is of no real consequence, as this data is only required for 'towed' ToYos. We did standard CTD casts, which have been averaged as ToYos.
