Surface PAR was removed from many casts due to malfunction. PAR was removed from 2 casts due to the cap being left on. For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". SBE Dissolved oxygen was recalibrated based on a comparison of the deepest cast derived using the pre-cruise calibration and the post-cruise calibration. Similarly, the temperature and conductivity were compared using pre-cruise and post-cruise calibrations. There was no significant drift in the temperature channels or the primary conductivity. There was significant drift in the secondary conductivity which is believed to have occurred after this cruise. Secondary temperature and salinity channels were selected for cast #445 only; no recalibration was found necessary since the temperature and conductivity channel pairs were very close throughout the cruise. Channel pH:SBE was removed because values at repeat casts varied greatly. NOTE: While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. It is recommended that users check extracted chlorophyll values where available.
