Mooring data discussion

Problems

Numerous problems were encountered with these datasets:

   * mooring 1 was never found
   * clock drift was observed in the VACM data upon recovery.
     This is thought to be caused by temperature-dependence of
     the clock circuitry.  An attempt was made to correct for
     this effect by applying a linear adjustment to the recorded
     times.
   * the quantitative pressure results are dubious - in some
     cases the uncorrected data show the sensors to be well above
     the sea surface!  Attempts were made to calculate a
     corrected quantitative pressure (column 9 in the VACM data
     files) by using VACM measurements made at the sea surface at
     the start and end of each deployment.   The qualitative
     changes are expected to be accurate.
