Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes\nand out-of-range values.\nThe initial configuration of the CTD for casts #1-22 is shown in table 1 below. For casts #23-62 , the CDOM sensor on channel A4 was replaced by the Chelsea Aquatracka fluorometer (as indicated in table 1 below) due to suspiciously high readings obtained using the Wetlabs FLBBRTD fluorometer near the water surface. The Chelsea unit yielded a similar response, providing confidence that the\nunexpectedly high chlorophyll readings near the surface were not caused by sensor issues.\nThe final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0013744 PSU, well within our target of \u2018better than 0.002 PSU\u2019. The standard product of 1-decibar binned averages were produced using data from the secondary sensors.\nThe dissolved oxygen data (primary) calibration fit had a SD of 0.7868 \u03bcM. The agreement between the CTD and bottle data was good.\nAdditional sensors include: SUNA Nitrate, Altimeter (Tritech PA500), Transmissometer (Wetlabs CStar), CDOM (replaced by Chealsea Aquatracka after cast #22), Chlorophyll-a, Scattering (Wetlabs ECO FLCDRTD) were installed on the auxiliary A/D channels of the CTD.\nThe collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).\nAdditional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.", "num_resources": 11, "num_tags": 0, "organization": {"id": "c0017ec2-e0d5-4e64-9238-27110ef01b78", "name": "csiro-marlin-data-catalogue", "title": "CSIRO Marlin Data
