Experiment name: ACM8 (German component) Principal Investigator: J.Meincke/E.Mittelstaedt PI's affiliation: B.S.H.Hamburg Mooring Name: A4 Mooring position: 59.152 deg N, 34.000 deg W Instrument depth: 269 meters Seafloor depth: 2850 meters Times: starts 31 May 1994, ends 10 Jun 1995 Time increment: 60 minutes Instrument type: Aanderaa RCM7 parameter min mean max sd days speed (cm/sec) 0.01 18.59 50.21 11.04 374.9 dir (deg true) 0.15 158.24 359.72 118.82 374.9 u (cm/sec) -35.90 3.17 46.57 14.68 374.9 v (cm/sec) -45.54 4.82 49.46 14.78 374.9 temp (deg C) 3.41 4.77 7.58 0.61 374.9 pressure (db) 104.80 123.56 336.56 26.24 374.9 There are some unusual and abrupt direction shifts in this record, from about 330 degrees to about 90 degrees. This behavior occupies only a small fraction of the total length of the file, but does occur on several occasions throughout the record. The direction series from some other instruments on the mooring behave similarly at approximately the same times, which suggests that the sudden veering is genuine.
