Sensors are factory calibrated once per year. Accuracy of the temperature probes is better than 0.005 degrees C based on manufacturer specifications. Accuracy of the salinity values is better than 0.02 based on expected maximum drift of conductivity cell between annual factory calibrations. Ancillary data are reported as voltages (full range 0-5 volts) and/or as converted to engineering units described at the top of the data file and have not been subjected to any quality control measures.\",\n",
