21. T and C response times are known In moored pumped instruments such as the 37 SMP MicroCAT the pump flushes 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 SMP 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 shallow depth air bubbles from breaking waves or spontaneous formation in supersaturated conditions can cause the conductivity cell to read low of correct 66 Manual revision 015 Glossa SBE 37 SMP RS 485 Glossary Note All Sea Bird software listed was designed to work with a computer running Windows 2000 XP Extensive testing has not shown any compatibility problems when using the software with a computer running Windows Vista or Windows 7 32
22. Unreasonable T C or P Data The symptom of this problem is a data file that contains unreasonable values for example values that are outside the expected range of the data Cause Solution 1 A data file with unreasonable i e out of the expected range values for temperature conductivity or pressure may be caused by incorrect calibration coefficients in the MicroCAT Send iiGetCC to verify the calibration coefficients in the MicroCAT match the instrument Calibration Certificates Note that calibration coefficients do not affect the raw data stored in MicroCAT memory e If you have not yet overwritten the memory with new data you can correct the coefficients and then upload the data again e Ifyou have overwritten the memory with new data you can manually correct the coefficients in the xmlcon configuration file and then reprocess the data in SBE Data Processing s Data Conversion module 65 Manual revision 015 Section 6 Troubleshooting SBE 37 SMP RS 485 Cause Solution 2 Minimal changes in conductivity are an indication that the pump flow is not correct Poor flushing can have several causes e Air in the plumbing may be preventing the pump from priming This can result from A clogged air bleed hole clean the air bleed hole see Plumbing Maintenance in Section 5 Routine Maintenance and Calibration Incorrect orientation for a shallow deployment in a location with breaking waves see Optimizing Data Quality
