******** NOTES *******************************************************

Deployment a - 12 March 1999 - 07 July 1999


The bio-optical package was moored at 40 m depth on the
mooring cable.  The basic sample interval was 3.75 minutes.

1. The nominal position of the mooring is the designed deployment site
   and actual deployments varied by about 0.5 nm around this position.
2. Sensor depths are nominal designed depths.  In water sensors vary
   around this designed depth by about 1 m, variation larger at grester
   distance below buoy.
3. Averaged PAR is about 200 samples averaged over the sample
   interval, while spot PAR is a single sample at the interval.
4. Temperatures are listed in the IPTS68 standard, rather than IPT90.
5. Salinity conversion from conductivity was done with PSS78
6. Sensor normalization was done with pre-cruise calibrations, and checked
   with post-cruise calibrations
7. Only minor editing has been done to remove spikes from records (see
   modifications above).
8. No corrections have been made to fluorometer and transmissometer data
   to remove biological fouling induced drift.
9. No corrections have been made to salinity for drifts due to biological
   fouling.
