CTDEDIT was used to remove records from the top and bottom of the cast. Data Processing Notes: ---------------------- The pressure sensor was reading very low so has been recalibrated by adding 2.5db. There were only 3 salinity calibration bottles, but they suggest that the CTD salinity is within ±0.01.
