values have been corrected.
Instrument characteristics and calibration factors
Teleost Pressure Recorder, sensor S/G, serial number 284
Original sampling interval 15 minutes
Integration period 900s
Temperature coefficient -1.78Hz/degC
Pressure sensitivity at 9.867degC 0.0775Hz/mb
To convert pressure to elevation the following
values should be used:
