The CTD probe was stationary when the water-sampling bottle was triggered. Note that the Driftcheck for P-Offset was performed at 15m. 6018 : Due to the anomalous nature of the cell constant calculated from the calibration bottle for this profile, a cell constant for use had been interpolated from the adjacent values (6002, 6004). However, the Dalhousie data were found to inconsistent with this cell constant and consistent with the originally calculated cell constant. The latter has been reinstated.
