Experiment name: SCM2 Principal Investigator: E.Fahrbach Affiliation: Alfred Wegener Inst. Mooring name: AWI228-4 Mooring position: 56.917 deg S, 0.046 deg E Instrument depth: 307 meters Seafloor depth: 3800 meters Times: 1600 04 Mar 1999 to 1000 30 Dec 1999 Time increment: 120 minutes Instrument type: Falmouth 3D-ACM parameter min mean max stddev days speed (cm/sec) 0.02 7.73 30.80 4.78 300.83 dir (deg true) 0.05 138.10 359.80 112.53 300.83 u (cm/sec) -19.95 2.75 24.20 5.58 300.83 v (cm/sec) -17.45 3.09 21.88 5.87 300.83 w (cm/sec) -6.89 -0.55 4.58 1.15 300.83 temp (deg C) -0.50 0.50 1.38 0.25 300.83 pressure (db) 304.90 306.64 351.00 2.90 300.83 salinity (psu) 34.56 34.66 34.73 0.03 300.83 On two occasions (13 Jun 99 and 10 Nov 99) the mooring experienced a disturbance that resulted in a pressure spike at all depths and a brief speed increase at every depth except that of the deepest instrument. On 13 Jun 99 the upper portion of the mooring plunged about 50 meters. The depth increase on 10 Nov 99 was about half that.
