control was made on the data except for manufacturer's calibration of the CTD sensors
generally conducted once a year. In particular, calibrations for chlorophyll and DO
sensors were not made regularly. Please use these values only for advisory.
We and the cruise directors do not warrant or take any responsibility for the accuracy
and reliability of the data, and any detriment with respect to the database information.
