The pressure record shows that the rig suffered knockdown on occasions throughout the deployment; the most severe displacement of this meter was of the order of 130m and occured on 25 May 82. However, CMDAC notes that the minimum pressure recorded, 1039.9 db, translates to a depth of about 1030 m, which is close to the depth given for the meter (1035 m). The mean pressure, 1048.42 db, is equivalent to a depth of approximately 1038 m. Thus CMDAC thinks that the pressures recorded by this meter may be reasonably accurate. The first 8 days of the temperature series originally contained numerous spikes that probably were instrument errors. These have been smoothed by linear interpolation in the present version of the record. This record was made with an Aanderaa current meter. The nominal speed threshhold of this meter is 1.5 cm/sec, and a common practice is to set below-threshhold speeds either to the threshhold value or to half the threshhold. In this case, however, below-threshhold speeds were set to zero by the originating PI, as were concurrent directions. In processing historical data CMDAC normally resets below-threshhold Aanderaa speeds to half the threshhold, but has not done so in this case because the direction information has been lost.
