Experiment name: ACM12 (Deep Basin) Principal Investigator: W.Zenk PI's affiliation: IFM-Kiel Mooring Name: VE/338 Mooring position: 31.137 deg S, 39.433 deg W Instrument depth: 1100 meters Seafloor depth: 4675 meters Times: starts 12 Jan 1991, ends 05 Dec 1992 Time increment: 120 minutes Instrument type: Aanderaa RCM8 parameter min mean max sd days speed (cm/sec) 0.99 4.58 22.60 4.11 694.0 dir (deg true) 0.00 216.62 359.78 95.56 694.0 u (cm/sec) -19.94 -1.54 16.26 4.24 694.0 v (cm/sec) -20.11 -0.04 20.35 4.19 694.0 temp (deg C) 3.33 3.98 4.72 0.20 694.0 pressure (db) 1059.50 1098.10 1174.80 10.82 694.0 Approximately 31% of the speeds registered by this current meter were at or below the instrument's threshold, and have been set to the threshold value (1 cm/sec). On 18 Apr 91 pressure decreased suddenly by about 45 db, then returned to its previous level about 3 weeks later. This decrease is not correlated with any variations in the pressure record from the current meter above this one, and appears to be an instrument error of some kind.
