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 Fluorescence data were removed from casts #64-74 due to very spiky data throughout the profile or because there was no signal at all. The PAR channel was removed from casts #30-34 because there was no signal. The SBE dissolved oxygen data in the CTD files are considered, roughly: • ±0.5 ml/l from 0– 25db • ±0.2 ml/l from 25– 200db • ±0.06 ml/l below 200db ------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
