===============================================================================
Additional information stored with the data:
Station D, Celtic Sea.
No timing scans on recovery. On previous deployments of this tide gauge in
1976 and 1977 suggested a clock gain of 0.01 seconds per hour. This gain
has been assumed for this deployment also.
Instrument characteristics and calibration factors
OSTG Mk II, logger 02, sensor DIG DS 6/2
Original sampling interval 15 minutes
Integration period 900s
Temperature coefficient 0.0mb/degC
Pressure sensitivity at 8.89degC 0.1545Hz/mb
To convert pressure to elevation the following
values should be used:
