Experiment name: SCM7 Principal Investigator: E.Fahrbach PI's affiliation: Alfred Wegener Inst. Mooring Name: AWI207-2 Mooring position: 63.752 deg S, 50.905 deg W Instrument depth: 300 meters Seafloor depth: 2460 meters Times: starts 23 Nov 1990, ends 19 Dec 1991 Time increment: 120 minutes Instrument type: Aanderaa RCM parameter min mean max sd days speed (cm/sec) 0.00 6.03 24.93 4.59 193.2 dir (deg true) 0.00 179.56 359.71 124.51 193.2 u (cm/sec) -15.31 -0.27 13.88 3.77 193.2 v (cm/sec) -24.03 2.28 24.21 6.16 193.2 temp (deg C) -0.78 0.16 0.52 0.19 342.6 pressure (db) 285.40 299.81 403.50 11.38 391.4 salinity (psu) 27.67 28.01 28.87 0.18 274.0 Speed and direction end early in this record, on 4 Jun 91. Salinity ends early, on 24 Aug 91. Temperature ends on 31 Oct 92. The longest series, pressure, continues until 19 Dec 91. The pressure record shows a sudden increase of about 110 db on 29 Jun 91. The pressure then decreases and settles at a value approximately 25 db greater than the previous average. A similar depth excursion is evident in the pressure record from the instrument below this one on the mooring, at 1010 meters. The cause is unknown; the mooring may have been dragged and then released in slightly deeper water.
