2-nd annual Meeting, June , Istanbul, Turkey Difficulties encountered: Many duplicates of oceanographic stations for one cruise, selected the CDI checker program. Reason: The Russian data are the time series in frame one cruise or many times the oceanographic stations for one fixed point. Propose: It need to modify the CDI checker program. The rule: If the coordinates (latitude and longitude) of oceanographic stations are identical and times are differing more 30 minutes, than these stations no duplicates.
