Experiment name: Denmark Str Ovfl (ACM8) Principal Investigator: R.Dickson PI's affiliation: MAFF Mooring Name: 8910 Mooring position: 63.557 deg N, 36.505 deg W Instrument depth: 1747 meters Seafloor depth: 1767 meters Times: starts 03 Jul 1989, ends 01 Nov 1990 Time increment: 60 minutes Instrument type: Aanderaa RCM5 parameter min mean max sd days speed (cm/sec) 1.50 28.94 58.80 11.05 120.8 dir (deg true) 37.87 242.92 349.64 27.55 120.8 u (cm/sec) -57.48 -24.07 23.22 11.86 120.8 v (cm/sec) -51.68 -11.25 35.86 10.65 120.8 temp (deg C) 0.86 1.85 3.11 0.47 120.8 MAFF notes that the quality of this record is poor after the first 54 days, but that its speeds and directions are in good agreement with those from the meter above this one on the mooring. The speed series of this record contains a large number of spikes that appear to be instrument errors. CMDAC has prepared an alternate file in which the data have been smoothed in two steps: First, many individual speed spikes were removed by linear interpolation. Second, all of the time series (u, v, and tempterature) were smoothed further by passing them through a low pass cosine-lanczos filter. This filter removes completely all frequencies higher than 4 cycles per day; frequencies lower than 6.6 cycles per day are passed unattenuated. Both the original version of this file and the value-added version are available on this disk.
