INFORMATION FOR BODC SERIES REF. NO. 33761 =============================================================================== Sea Floor Pressure Gauge Inventory Number : 6948 Start Time : 06 Sep 1973 2052 GMT Latitude : 52deg 28.0min N End Time : 19 Oct 1973 1622 GMT Longitude : 002deg 13.0min E Nominal Cycle Interval : 900.0 secs Sensor Depth : 39.00m Sea Floor Depth : 39.00m Positional Uncertainty : 0.1 to 0.5 n.miles Depth Datum : Instantaneous Project : JONSDAP 1973 Data Category : Offshore sea floor pressure series Instrument Type : Tide gauge (unspecified) Instrument Mounting : Sea floor - fixed Originator Laboratory : Proudman Oceanographic Laboratory, Bidston, UK Originator's Identifier : 736/973/249 =============================================================================== Additional information stored with the data: Station WI, Southern North Sea Clock lost 2 seconds over 60 days, 15.5 hours; the cycle interval and time values have been corrected. Instrument characteristics and calibration factors OSTG Mk II, logger 03, sensor VIB 1/2 Original sampling interval 15 minutes Integration period 900s Temperature coefficient 5.1cm/degC Pressure sensitivity at 14.7degC 0.0389Hz/cm To convert pressure to elevation the following values should be used: Density (from CTD casts) 1024.967kg/m3 Gravitational acceleration constant 9.813m/s2 The following gap occurs in the data record due to a logger malfunction which caused the tape drive to stop and restart: 1623h 14 Sept 1973 - 0923h 27 Sept 1973 ------------------------------------------------------------------------------- The following additional documents apply to this series: 27731; I.O.S.
