Speyside CREWSannual maintenance

The Speyside CREWS was given an annual maintenance check over the period 10-13 Nov 2014. The buoy was brought to shore and all instruments were functioning and we had no problem connecting via RF but there was no cellular connection.  All data for the last year was downloaded from both loggers and is now in the hands of TT IMA.  The programs were re-loaded and the electronics were reset.  Cellular communications was restored immediately afterward.  The RMY temp/RH is in need of service/calibration  but all other MET sensors seem to be measuring accurately.  The Temp/RH was removed for service and sonde recalibrated  prior to re-deployment on the 11 Nov 2014.

On the previous basic servicing (September 2014), the sonde was not functional due to erupted batteries in the battery well.  These were replaced.  The Temp/Cond was also found to be faulty, which was eventually returned to and replaced by YSI.

The breakage of the wiper parking garage has been noted as a regular problem with the CREWS inhibiting the proper settling of the wipers, and may be something the design team should look at.
