Additional information stored with the data:
Station 53, Northern North Sea
Clock gained 69 seconds over 58 days, 2.75 hours; the cycle interval and
time values have been corrected.
Instrument characteristics and calibration factors
Aanderaa Current meter/Pressure recorder, logger 1747, sensor DIG 5/2
Original sampling interval 15 minutes
Integration period 900s
Temperature data record from current meter 1747
Temperature coefficient -0.61Hz/degC
Pressure sensitivity at 4.0degC 6.547mb/Hz
To convert pressure to elevation the following
values should be used:
Density (from CTD casts) 1027.324kg/m3
Gravitational acceleration constant 9.818m/s2
A current meter was also deployed on this mooring.
