Its embedded firmware controls all of the instrument's functions. It is designed for profiling to depths of up to 100m at 5 Hz. It uses a six electrode flow-through conductivity cell with zero external field coupled with a rapid response thermistor (<5Hz) to attain high measurement accuracies. The instrument does not require a pump and is hydrodynamically designed to free fall rate of 1 m/s. Processing was done using the CastAway CTD data processing system which included the following steps: - Pressure correction to remove ambient atmospheric pressure. - Removal of records obtained while the system was stationary. - De-spiking of conductivity data to remove erratic measurements near the water surface that can be caused by air bubbles trapped in the conductivity flow cell. - Bin-averaging with 0.3db bins with linear interpolation used to fill empty bins or the nearest available value for surface or bottom bins. - Combination of downcast and upcast data using a weighted average based on fall velocity. - Derivation of specific conductance, salinity, sound speed, density and depth for each pressure bin. The data were converted to IOS Header format and some quality control checks were made. Resolution and Accuracy as stated by the manufacturer is: Channel Resolution Accuracy Pressure 0.01 db 0.25 db Depth 0.01 m 0.25 m Temperature 0.01 degrees C 0.05 degrees C Conductivity 1 mS/cm 5 mS/cm Conductance:Specific 1 mS/cm 5 mS/cm Salinity 0.01 (PSS-78) 0.1 (PSS-78) Speed:Sound 0.01 m/s 0.15 m/s Density 0.004 kg/m3 0.02 kg/m3 GPS 10m Density is derived based on temperature resolution and accuracy using the International Equation of State for sea water (EOS-80). Depth and Specific Conductance are derived using the International Equation of State for sea water (EOS-80). Salinity was calculated using the 1978 Practical Salinity Scale. Sound Speed was calculated using the method of Chen-Millero, 1977.
