===============================================================================
Additional information stored with the data:
Station B, Celtic Sea.
On recovery instrument had stopped due to a flat battery, so no timings at
the end of the record were available, hence no time corrections made.
Instrument characteristics and calibration factors
Aanderaa Current meter/Pressure recorder, logger 1747, sensor DIG 280
Original sampling interval 15 minutes
Integration period 900s
No temperature correction made
Pressure sensitivity at 7.66degC 0.1525Hz/mb
To convert pressure to elevation the following
values should be used:
Density (from CTD casts) 1027.0Kg/m3
Gravitational acceleration constant 9.812m/s2
