Additional information stored with the data:
Station G, Celtic Sea.
Clock lost 14 seconds over 49 days, 20.25 hours; the cycle interval and
time values have been corrected.
Instrument characteristics and calibration factors
Aanderaa Current meter/Pressure recorder, logger 302, sensor DIG 4161
Original sampling interval 15 minutes
