Ice trapped in the side arms of the C-cell. Probe retrieved prior to the recorded cast in order to eliminate the problem. 6010 : Since the conductivity ratio on this profile is quite unstable (+/- 0.012 in salinity), a cell constant of 1.00000 was assigned arbitrarily for the initial stages of processing. More careful consideration of the editted profile data, in conjunction with the salinity sample, has allowed the estimation of a cell constant (1.035867). Also, during this station the temperature sensor showed a jump in calibration, and the calibration offset estimated during the cal-check is not appropriate during the profile. The mixed-layer temperature measured by thermistor prior to the profile was used to calibrate the profile, and a new T_OFFSET (+0.0069 C) has been used.
