61. g s Derive module from the converted cnv file Background information Salinity spikes in profiling i e moving fast sampling instruments typically result from misalignment of the temperature and conductivity measurements in conditions with sharp gradients This misalignment is often caused by differences in response times for the temperature and conductivity sensors and can be corrected for in post processing if the T and C response times are known In moored free flushing instruments such as the 37 SI MicroCAT wave action mooring motion and currents flush the conductivity cell at a faster rate than the environment changes so the T and C measurements stay closely synchronized with the environment i e even slow or varying response times are not significant factors in the salinity calculation More typical causes of salinity spikes in a moored 37 SI include Cause Solution 1 Severe external bio fouling can restrict flow through the conductivity cell to such an extent that the conductivity measurement is significantly delayed from the temperature measurement Cause Solution 2 For a MicroCAT moored at shallow depth differential solar heating can cause the actual temperature inside the conductivity cell to differ from the temperature measured by the thermistor Salinity spikes associated mainly with daytime measurements during sunny conditions may be caused by this phenomenon Cause Solution 3 For a MicroCAT moored at shal
