Additional information stored with the data:
Station BC3, Bristol Channel.
Clock gained 18 seconds over 36 days, 0.25 hours; the cycle interval and
time values have been corrected.
Instrument characteristics and calibration factors
Teleost Pressure Recorder, sensor S/G, serial number 281
Original sampling interval 15 minutes
Integration period 900s
No temperature correction made
Temperature coefficient -0.495Hz/degC
Pressure sensitivity at 9.867degC 0.0780Hz/mb
To convert pressure to elevation the following
values should be used:
Density 1027kg/m3
Gravitational acceleration constant 9.812m/s2
On recovery mud was found on one side of the frame as if the rig had been
held in mud. Density calculated from measured temperatures and a regional
salinity of 35 parts per thousand.
