Additional information stored with the data:
Station C4, South west continental shelf
Clock lost 11 seconds over 46 days, 4.5 hours; the cycle interval and
time values have been corrected.
Instrument characteristics and calibration factors
OSTG Mk II, logger 05, sensor VIB 1/5
Original sampling interval 15 minutes
