<li>Most information regarding individual profiles is provided with the individual data files (location, correction to GMT, light units, sensor type and characteristics, date of latest calibration).</li>
<li>Upcast and downcast profiles sorted separately by depth, then time. Downcast listed first. Raw values listed - no averaging.</li>
<li>All profiles were taken with the same two (Biospherical Instruments, Inc. San Diego, CA) instruments: underwater unit (PUV-500) and matched deck unit (PUV-510). Last Calibration of Sensors: 15 DEC 95.</li>
<li>The December 1995 recalibration results have been applied to all readings. The change in calibrations from the previous April 1993 factory measurements were less than 2%.</li>
<li>All profiles were taken from same location on the R/V Endeavor: starboard side using the J-frame. Whenever sea condition allowed, the ship was turned such that the sun was shining on the starboard side and as close to amidship as possible.</li>
