The gap between the two deployments of Mooring A5 that make up this record is 16 hours long, on 04/05 May 93. The pressure record from the instrument deployed after the gap indicates that this instrument was about 150 meters shallower than the current meter used before the gap. However, pressure records from other depths on this mooring show no such discrepancy. We conclude that the pressure sensor used at 1900 meters after the gap was incorrectly calibrated or otherwise malfunctioned. In any case, we have deleted pressure from that portion of the joined record. Thus the pressure record ends early at line 6128 (1000 04 May 93).
