Experiment name: Iceland-Faroe Overflow (ACM8) Principal Investigator: P.Saunders PI's affiliation: Inst. Oceanog. Sci. (UK) Mooring Name: 502 (B) Mooring position: 63.143 deg N, 17.297 deg W Instrument depth: 1018 meters Seafloor depth: 1028 meters Times: starts 14 Jul 1990, ends 14 Aug 1991 Time increment: 60 minutes Instrument type: Aanderaa RCM5 parameter min mean max sd days speed (cm/sec) 2.79 8.22 32.49 3.73 395.8 dir (deg true) 0.10 206.36 359.73 95.39 395.8 U (cm/sec) -29.56 -1.84 19.31 6.49 395.8 V (cm/sec) -25.31 -0.78 19.38 5.95 395.8 temp (deg C) 3.80 4.95 5.89 0.27 395.8 pressure (db) 981.87 1015.39 1134.31 7.47 395.8 The speed series in this record contains some apparent interpolations during 12 to 14 May 91. The temperature series contains an anomalous 3-hour spike starting at 1530 31 Aug 90 (line 1147). This spike was not present in a low-resolution recording made by the same current meter, and is almost certainly an instrument error. This record's pressure series is problematical. It displays a tendency to stick at two values, 1029.9 db and 1013.3 db, alternating between them much of the time. This evidently is an artifact, since the resolution of the sensor is much less than the difference between the two values. Note also that the maximum recorded pressure, 1134 db, is greater than the water depth, 1028 m. CMDAC has prepared an alternate version of the file in which the temperature spike mentioned above has been smoothed by linear interpolation, and the questionable pressure series has been removed. Both versions of the file are available on this disk.
