CTDEDIT was used to remove records from the surface and bottom of the cast and many records corrupted by shed wakes; salinity was cleaned lightly. ------------------------------------------------------------------------- Transmissivity and fluorescence data are nominal and unedited except that some records were removed in editing temperature and salinity. Transmissometer #1005DR was calibrated in March 2008, and drifted significantly but steadily until July 2009; then a sudden shift occurred, so that maximum values between September 2009 and July 2010 were very low, ~25%/m. In August 2010 a study was made of transmissivity that led to a decision to apply corrections to all cruises between March 2008 and June 2010. The data are still considered nominal. For details see file Transmissometer 1005DR Corrections.doc in OSD_Data_Library:\Cruise_Data\DOCUMENTS The SBE dissolved oxygen data in the CTD files are considered, roughly: • ±1 ml/l from 0–10 db • ±0.5 ml/l from 10–30 db • ±0.2 ml/l below 30db For details on processing see file 2010-28-proc.doc. ------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
