There was no calibration sampling. The range set for the pressure sensor in acquisition was 10153db where it was in fact 1450db. This led to very high pressure values starting at about 87db. Values were corrected by assuming that the surface pressure was 0db. CALIBRATE was run to recalibrate the pressure channel choosing: Scale Factor 1450/10153 = 0.1428 Offset: Surface pressure -86.6db * scale factor = -12.370 After recalibration depths were recalculated and maximum values were lower than log entries for water depth by an appropriate amount (average 6m - range 1m to 10m). Warning: While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples.
