NO. 37798 =============================================================================== Sea Floor Pressure Gauge Inventory Number : 7010 Start Time : 19 Jul 1970 1822 GMT Latitude : 56deg 00.4min N End Time : 12 Aug 1970 1409 GMT Longitude : 008deg 35.1min W Nominal Cycle Interval : 900.0 secs Sensor Depth : 138.00m Sea Floor Depth : 138.00m Positional Uncertainty : 0.1 to 0.5 n.miles Depth Datum : Instantaneous 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 : POS14JUL70 =============================================================================== Additional information stored with the data: I.O.S. Data Processing of Off-Shore Pressure Recorder Data 2 1. Because the pressure is integrated over 890 seconds and then logged, the time value assigned to a data cycle has been chosen as the mid-point between the start and end of each integration period. 2. Instrumental drift and depth have been removed, thus a drift free series is produced with an artificial mean value. -------------------- Clock lost 1 minute 53 seconds over 29 days 9 hours 1 minute 53 seconds; the cycle interval and time values have been corrected. Instrument Characteristics Station 14 OSTG Mk I no. 1 Nominal sampling interval 900secs Integration period 890secs Actual sampling interval 15.00070mins ------------------------------------------------------------------------------- The following additional documents apply to this series: 27728; Off-Shore Tide Gauge Type I ===============================================================================
