Experiment name: Denmark Str Ovfl (ACM8) Principal Investigator: R.Dickson PI's affiliation: MAFF Lowestoft Mooring Name: 9006 Mooring position: 63.622 deg N, 32.927 deg W Instrument depth: 2638 meters Seafloor depth: 2738 meters Times: starts 12 Jul 1990, ends 12 Jul 1991 Time increment: 60 minutes Instrument type: Aanderaa RCM5 parameter min mean max sd days speed (cm/sec) 0.58 11.03 52.98 6.47 365.0 dir (deg true) 0.15 182.22 359.98 109.28 365.0 U (cm/sec) -52.96 -0.28 28.18 10.21 365.0 V (cm/sec) -28.87 1.51 34.60 7.54 365.0 temp (deg C) 1.13 2.28 3.04 0.32 365.0 MAFF's comment: "There is a noticeable shortage of current directions recorded between 114 and 186 degrees. Is this real? Note that the histogram of directions is similar to that from the meter above." The speed series contains large numbers of spikes that appear to be instrument errors. CMDAC has prepared an alternate file in which the data were smoothed in two steps: First, many individual spikes were removed by linear interpolation. Second, u and v (and implicitly speed and direction) were smoothed further by passing both series through a hanning filter, which has weights 1/4, 1/2, and 1/4. Both the original file and the alternate version are available on this disk.
