Additional information stored with the data:
Station E, North Channel.
Clock gained 3 seconds over 62 days, 8.25 hours; the cycle interval and
time values have been corrected.
Instrument characteristics and calibration factors
Teleost Pressure Recorder, sensor DIG, serial number 280
Original sampling interval 15 minutes
Integration period 900s
Temperature coefficient -0.927Hz/degC
Pressure sensitivity at 9.647degC 0.183Hz/mb
To convert pressure to elevation the following
values should be used:
Density (from CTD casts) 1026.05kg/m3
Gravitational acceleration constant 9.815m/s2
A current meter was deployed on this rig, 6m above the tide gauge.
