Experiment name: ACM8 (Denmark Str Ovfl) Principal Investigator: R.Dickson PI's affiliation: CEFAS Mooring Name: 9603 Mooring position: 63.487 deg N, 36.278 deg W Instrument depth: 1849 meters Seafloor depth: 1949 meters Times: starts 30 Jul 1997, ends 18 Aug 1997 Time increment: 60 minutes Instrument type: Aanderaa RCM8 parameter min mean max sd days speed (cm/sec) 2.81 26.75 56.10 11.71 18.9 dir (deg true) 121.31 245.84 328.99 41.91 18.9 u (cm/sec) -54.68 -21.22 27.02 15.70 18.9 v (cm/sec) -30.20 -6.04 24.26 10.92 18.9 temp (deg C) 1.43 2.09 2.98 0.39 18.9 pressure (db) 1869.40 1872.88 1881.90 3.32 18.9 Accessions 2507 and 2508 (this one) are from the same current meter record. Apparently the meter stopped for 42 minutes on 30 July 1997 (at the end of Accession 2507) and then restarted. One record was lost, and the time base changed. Because of the change of time base (the measurements in Accession 2507 lie 30 minutes after the hour, and those in Accession 2508 lie 17 minutes after the hour) the record has been processed as two files. A comment by CEFAS: The pressure sensor records 1876 db at the start of the series [i.e., at the start of Accession 2507], approximating to a depth of 1849 m. This is in excellent agreement with the expected meter height of 100 m in a water depth of 1949 m. The pressure estimates decrease near the end of the series from 1869 db on 14/7/97 to a minimum of 1851 db. This corresponds to a decrease in bit value of only 3 and may be an indication of a power problem (the clock appears to have stopped shortly after this). At the start of the complementary series [Accession 2508, the present file] a few hours later, the pressure recording is 1876 db.
