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

===============================================================================
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
